CF 902 hotfixes, is the GUI needed?

Hi All
Recently i have applied hotfixes
http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb12-26.html
http://helpx.adobe.com/coldfusion/kb/coldfusion-security-hotfix-apsb12-21.html
to numerous servers.
One of the steps to install the hotfixes is to manually select the hotfix via the GUI and hitting submit.
My query is this - Does the GUI simply put the hotfix in the location update location? Or does it do more behind the scenes?
The reason why i'm asking is because should i have to update multiple servers in the future, it would be much quicker and easier just to place the hotfix directly in that hotfix update location and avoid the GUI altogether
Cheers in advance

Yes, you can directly copy the hotfix jar file to the updates directory to apply the hotfix.

Need Help to update the labels in the GUI syncronously - Swing application

Hello everyone,
I need some help regarding a swing application. I am not able to syncronously update the counters and labels that display on my Swing GUI as the application runs in the background. But when the running of application is completed, then the labels on the GUI are getting updated, But I want update the labels and counters on the GUI syncronously as the code executes... below I am giving the format of the code I have written..............
public class SwingApp extends JFrame{
        // here i have declared the label and component varibles like...

First off, note that this question should have been posted in the Swing section.
GUI events run in a separate thread (the AWT / Event Dispatch Thread) than your program.
You should be invoking AWT/Swing events via SwingUtilities.invokeLater().
If for whatever reason you want to have the program thread wait for the event to process
you can use invokeAndWait().

What would impact if SAP GUI needs to be upgraded to the lates version 710

Hi guys
could you tell me ..
if we will do upgrade "SAP GUI needs to be upgraded to the lates version 710"
what would be the impact to 'end user GUI' and how we are addressing it?

Hi,
what do you mean by end user GUI... is that portal impact are you talking about?
also check the below threads
sap Gui 7.1

I need help with the GUI nad Graphic 2D....

Hi
i'm kind new to java and i have couple of questions... all my questions about the GUI...
when i want to create a GUI programe , and when i want to draw a graphic with GUI, i do that way(code)
"public class x1 extends JPanle{
public void PaintComponent(Graphic g){
My questions:
1) why do i have to extend from JPanle ??
2) Why do i use paintcomponent??? why i couldn't use directly 'Graphic g' ??
This code i get it from the book, this is how it is done...
Also, if i want to draw some shapes(rec, circle ..etc) and i want to put Button and organize them, how could i do that???
i tried to organize the button after i draw the rectangle but i can't... all becaus of the stupid way'the code that i wrote it', i hope there is an alternative way.
My last question... how can i change the font ???
i want to use 'sans comic'...
Thanks alot....

i'm kind new to java and i have couple of questions...fair enough.
all my questions about the GUI...and that's your problem right there.
Your questions tell me that you're missing quite a few fundamentals of programming in Java. There's nothing wrong with that, everyone starts this way. But if you try to do any GUI programming at your current level you will run head-first into many, many problems that could be easily avoided if you concentrate on learning the basics first.
when i want to create a GUI programe , and when i want to draw a graphic with GUI, i do that way(code)
"public class x1 extends JPanle{That code doesn't compile. It's JPanel, not JPanle. Please post only compiling code (or near it, if you've got a question about a compiler error).
public void PaintComponent(Graphic g){"paintCompontent", not "PaintComponent".
Oh, and in the future please use the CODE-Button when posting code (1. copy+paste code 2. select code 3. press "CODE" just above the text area).
My questions:
1) why do i have to extend from JPanle ??You don't have to. You can, if you want your class to be a specific type of JPanel.
2) Why do i use paintcomponent??? why i couldn't use directly 'Graphic g' ??How would you "directly use Graphic g"?
That's the way the framework is written. Components draw themselves using that method. If you want to change how they draw themselves you can override that method.
Did you read the chapter that tells you this or did you simply copy out the code example? The examples are there to illustrate the points and help you understand. They are not a *substitute* to actually reading the text.
Also, if i want to draw some shapes(rec, circle ..etc) and i want to put Button and organize them, how could i do that???Finish reading the book, write some basic programs and then work on from there.
You're trying to learn a feature and produce a useful product at the same time. I can tell you from experience that this is a very bad idea.
i tried to organize the button after i draw the rectangle but i can't... How did you try?
all becaus of the stupid way'the code that i wrote it', i hope there is an alternative way.You didn't show us your attempt so we can't tell you any alternative.
My last question... how can i change the font ???
i want to use 'sans comic'... Hm ... "Comic Sans" is the name. And that's not a font. [It's a desease|http://bancomicsans.com/].

Unable to enter a Division for which I have proper credentials, via the GUI

I have a Division which I am unable to enter, either as a student or as the full site Administrator, from the GUI.
When I log into the main Site page, I see the link for the Division (as I should - I have DOWNLOAD permissions for the Division). However when I click the link (the thumbnail image) I am always, 100% of the time, rejected and sent to the login page. Ignoring that, I still have all of my proper credentials and may continue to freely access other parts of the site.
In the past, I had this exact behavior on (1) a Division "RobotCourses:PSYC" (Psychology), and (2) my main site breadcrumb, which appears at the top of the site page to the right of the "iTunes U" breadcrumb and says "Maiko Covington @ University of Illinois..." For reasons completely unknown to me, this behavior resolved itself yesterday, clicking both of those objects works as expected, although NO one at our site with any edit access did anything on the server.
However, the same behavior has now reappeared, this time on a Division "RobotCourses:CLCV" (Classical Civilizations). Again, I have not done any editing of that Division, nor had anyone logged into it (these Divisions are in a test area where I am developing automation tools).
I am, quite frankly, stumped. But I've done some investigation.
SETUP:
The Division has identity "RobotCourses:CLCV".
This Division contains a single Course with identity "RobotCourses:CLCV:CLCV115:CLCV115All-13564".
Both the Division and the Course are restricted to properly registered academic students. I have developed automation code in a login portal which grants credentials for RobotCourses:CLCV to students registered for courses in the CLCV department (Classical Civilizations) and credentials for RobotCourses:CLCV:CLCV115:CLCV115All-13564 to students registered for CLCV 115 (Classical Civilizations 115 - Mythology of Greece and Rome) specifically.
The Permissions set on RobotCourses:CLCV in particular are:
<Permission>
<Credential>Authenticated@urn:mace:itunesu.com:sites:illinois.edu</Credential>
<Access>No Access</Access>
</Permission>
<Permission>
<Credential>gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV</C redential>
<Access>Download</Access>
</Permission>
The point is to deny access to Authenticated@ (merely authenticated students) and then specifically grant it for people given a "gakusei" credential for RobotCourses:CLCV in particular.
(Note here that "gakusei" is a Japanese word meaning "student," I am using it in my credentials to ensure that my credentials and permissions are not affected by other credentials named "student" set at upper levels and used by some live users of the site, as we do not have a segregated development environment. It is our lowest level of access beyond mere Authenticated@..., designed to give students access to download and "surf to" Divisions and Courses.)
*LOGIN: ISSUING CREDENTIALS:*
The login portal code works successfully, and so when a student "Jane Doe" logs in, she is in fact given appropriate credentials (as she is actually registered for CLCV 115 here at UIUC). From the code generating her login URL, I see:
Issued credentials:
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV:CLCV115:CLCV1 15All-13564
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT:STAT100:STAT1 00X1-13570
(You can see she is also registered for STAT 100).
With the default login URL thus generated, she is taken to the top level of the Site in iTunes, and in fact sees thumbnail links for both STAT (Statistics) and CLCV (Classical Civilizations). Clicking on STAT takes her to the STAT Division where she can then enter the Course STAT 100 with no problems.
*PROBLEM: CAN'T GET TO CLCV FROM THE MAIN PAGE IN THE GUI*
HOWEVER! Clicking on CLCV brings up the login page. If she ignores the login page, she can still access the rest of the site, including STAT, just fine. Logging in again (reissuing her credentials) does not help the situation.
Note that this is not a problem only for Jane Doe, the same thing happens for anyone in CLCV and in fact happens for me as Administrator of the whole site with full access, even.
*ACCESS DIRECTLY TO THE DIVISION BY URL WORKS*
With a slight modification to the login to allow access directly to the RobotCourses:CLCV Division (by adding the handle of the Division to the end of the location), credentials are issued exactly as before:
Issued credentials:
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV:CLCV115:CLCV1 15All-13564
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT
gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT:STAT100:STAT1 00X1-13570
and she is taken to the Division page, SUCCESSFULLY. So, it seems she actually HAS access, as expected.
*ACCESS CONFIRMED WITH DEBUGGING:*
Writing some code to generate not the actual login URL but rather a link that takes me to an "iTunes U Access Debugging" page for the Division (figured this out by reading some other posts! :)) I am taken to a page with the following:
(at generated URL https://deimos.apple.com/WebObjects/Core.woa/Browse/illinois.edu.1945806043/xxx5 64?credentials=....)

Signature 42ccef92a3298684a7a09eed45adb6b788a700c01645b8b423d33ace120650b0
Analysis
The destination string is valid and the corresponding destination item was found.
The identity string is valid and provides the following information:
Display Name Jane X Doe
Email Address [email protected]
Username jxdoe
User Identifier xxxxxxxxx
The credential string is valid and contains the following 4 recognized credentials:
1. gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV
2. gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:CLCV:CLCV115:CLCV1 15All-13564
3. gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT
4. gakusei@urn:mace:itunesu.com:sites:illinois.edu:RobotCourses:STAT:STAT100:STAT1 00X1-13570
The time string is valid and corresponds to 2009-03-12 17:12:27Z.
The signature string is valid.
Access
Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U.
In addition, the following 2 credentials were automatically added by iTunes U:
1. All@urn:mace:itunesu.com:sites:illinois.edu
2. Authenticated@urn:mace:itunesu.com:sites:illinois.edu
With these credentials, you have browsing and downloading access to the requested destination.
(In case you think to check the sums, be aware I've actually changed the student's name for this example.)
So, as expected, I have access, in fact the student DOES have access, visiting the Division page directly (specifiying its handle as part of the desired location).
*IT'S ONLY CLICKING THE THUMBNAIL ON THE MAIN PAGE THAT BREAKS*
Because the problem is only apparent when clicking the icon for the Division on the main Site page, I have no way (that I know of) to get any information about precisely WHAT is going on, what possibly differs in the GUI-click situation from the "generate me a URL that takes me right there" situation.
At that point I'm fully in the GUI, I'm not sending anything via web services, so I have no idea how I can proceed to debug this from here.
I'm also quite confused at the sudden appearance of this behavior, and the disappearance of this behavior from RobotCourses:PYSC, another Division that was broken in this same way all last week but which magically resumed allowing me access yesterday.
Any suggestions, hints, or advice would be very welcome. Has anyone else even seen behavior similar to this?
Thanks for any information you might have.

Maiko,
I'm confess I'm still trying to get a handle on your problem. You do a fantastic job of describing it ... but I'm just trying to picture it accurately in my head.
I think, were I in your shoes, I'd begin by looking at what the debug page has to say for the specific destination in which you're interested in fixing. In other words, I'm not clear on where, exactly, this destination points ...
Destination illinois.edu.1945806043
Is that your site, or the division within your site that you want to fix? "Normally", you do not need to specify a site handle to get to your site within your transfer CGI ... if you say "uillinois.edu", it's enough to transfer your users to iTunes U ... but every site still has a handle, and you could, if you wanted to, actually specify it in your transfer CGI. For example, this:
Destination uic.edu.1139051993
is for my entire site ... it's my site handle. Whereas this:
Destination uic.edu.1991288441
is for a division within my site ... but it's impossible to tell the difference between "site" and "division" from just the handle (I mean, if I didn't say "this is a site" and "this is a division", there'd be no way for you to know). So when I look at your creds and permissions on your debug page, I can't quite tell if they give you download access for your site, or for the specific division you want to fix. If you could open the debug page with your division as destination (or confirm that that's what we're looking at), it'd rule out some things.

How to create a user account by mirroring another account in PowerShell (Trying to learn to use Powshell for some daily AD tasks intead of the GUI)

Hi,
I am trying to create user accounts via PowerShell instead of the Gui in server 2008 R2 (PowerShell 2.0).
I know how to create a user account with the following Power Shell command below is one from a dummy domain I created to practice.
PS C:\Users\Administrator> New-ADUser -SamAccountName "TestOut" -UserPrincipalNa
me "[email protected]" -GivenName "Test" -Surname "out" -DisplayName "Testou
t" -Name "Testout" -Enabled $true -Path "CN=users,DC=bwcat,DC=net,DC=int" -Accou
ntPassword (Read-Host -AsSecureString "Enter Account Password")
However when doing day to day tasks where I work normally we have a new hire, they contact IT and ask that a user account is created. I will ask who they would like to mirror.
I then would go into the gui pull up the user that they want to mirror right click him and choose copy. This would create a new user account that I would then fill out.
I am wondering if its possible to do this same thing via PowerShell, or if its not an option because it takes more work type up everything than it does to go into the gui and do it.
Anyway thanks for the help.

Hi Wilder, hi Mark,
first of all: The tutorial sources Mark posted - especially the book "Powershell 3 in A month of lunches" - are good to get a baseline start. A really great reference, especially when you try to learn it while still dealing with your daily business.
On another note, Wilder: While I fully agree that learning things sequentially is usually the best, I too jumped right in instead of learning how to walk first (though it's been some time now. Fewer years than you'd think, but still ...). So I thought I'd
give you a little aid with that function husk, so you could just stuff interesting bits into an available structure, making use of the fun tools in a useful context (It's fun fiddling around with the commands, but if you have to type in all of them manually
each time, using the GUI is often just faster. Doing fun things and being efficient with it feels even better though ...). So ... while I
do agree with yourself, learn it the Correct & Proper Way, I also do
intend to finish this little explanation about the husk, all the way to the end.
Everything below this paragraph is part of this.

This is again the same function husk I posted earlier. Only this time, I filled a little logic (the pieces that were already posted in this thread). This time, I'll not only go over each part again ... I'll do it by reposting the segments and trying to show
some examples on how to modify the parts. Thus some of it will be repetitive, but this way all the info is in one spot.
Segment: Comment Based Help

.SYNOPSIS
A brief description of the Copy-ADUser function.
.DESCRIPTION
A detailed description of the Copy-ADUser function.
.PARAMETER GivenName
A description of the GivenName parameter.

.NOTES
Additional information about the function.
#>
That's the premier documentation part of a function, that teaches a user what the function does and how to use it. It's what's shown when using the Get-Help cmdlet.
Comment texts are not restricted to single lines however. For example you could replace ...
.EXAMPLE
PS C:\> Copy-ADUser -GivenName "Max" -Surname "Mustermann" -Template "Jonny.Normal"
... with ...
.EXAMPLE
PS C:\> Copy-ADUser -GivenName "Max" -Surname "Mustermann" -Template "Jonny.Normal"
Creates a new user named Max Mustermann and copies the group memberships of the already existing user Jonny Normal to this new User
... and get an explanation on what the example does when using Get-Help with the
-Detailed parameter (Explaining examples is always a good idea).
Segment: Parameter
[CmdletBinding()]
Param (
[Parameter(Mandatory = $true)]
[string]
$Surname,
[Parameter(Mandatory = $true)]
[string]
$GivenName,
[Parameter(Mandatory = $true)]
[string]
$Template
This is the segment that tells Powershell what input your function accepts. Each parameter of Copy-ADUser you set will be available in the next segment as a variable of the same name. You can add additional parameters if you need more information for your
logic. For example, let's add a parameter that allows you to specify what Organization the new user should belong to:
[CmdletBinding()]
Param (
[Parameter(Mandatory = $true)]
[string]
$Surname,
[Parameter(Mandatory = $true)]
[string]
$GivenName,
[string]
$Organization,
[Parameter(Mandatory = $true)]
[string]
$Template
That's how that would look like. You may notice that I didn't add the line with
"[Parameter(Mandatory = $true)] this time. This means you
may add the Organization parameter when calling Copy-ADUser, but you need not.
Segment: Logic
# Create new User
$NewUser = New-ADUser -Surname $Surname -GivenName $GivenName -DisplayName "$Surname, $GivenName" -SamAccountName "$GivenName.$Surename" -Name "$Surename, $GivenName" -PassThru
# Copy from old User
$NewUser | Add-ADPrincipalGroupMembership -MemberOf (Get-ADPrincipalGroupMembership $Template | Where { $_.Name -ne 'Domain Users' })
# Do Whatever else you feel like doing
This is the part of the function that does the actual work. Compared to the first husk I posted, this time there are two commands in it (and some comments). First, I create a new user, using the information passed into
the parameters -Surname and -GivenName. Then I Copy the group memberships of the user identified by the information given by the
-Template parameter.
So, let's modify it!
# Tell the user you are starting
Write-Host "Starting to create the user account for $GivenName $Surname"
# Create new User
$NewUser = New-ADUser -Surname $Surname -GivenName $GivenName -DisplayName "$Surname, $GivenName" -SamAccountName "$GivenName.$Surename" -Name "$Surename, $GivenName" -PassThru
# Tell the user you are copying Group Memberships
Write-Host "Copying the group-memberhips of $Template to $GivenName $Surname"
# Copy from old User
$NewUser | Add-ADPrincipalGroupMembership -MemberOf (Get-ADPrincipalGroupMembership $Template | Where { $_.Name -ne 'Domain Users' })
# Do Whatever else you feel like doing
Now after adding a few lines, the logic will tell us what it's doing (and do so before it
is taking action)!
Hm ... didn't we create a change in the Parameter Segment to add an -Organization parameter? Let's use it!
# If the -Organization parameter was set, the $Organization variable will be longer than 0. Thus do ...
if ($Organization.Length -gt 0)
# Tell the user you are starting
Write-Host "Starting to create the user account for $GivenName $Surname in the Organization $Organization"
# Create new User
$NewUser = New-ADUser -Surname $Surname -GivenName $GivenName -DisplayName "$Surname, $GivenName" -SamAccountName "$GivenName.$Surename" -Name "$Surename, $GivenName" -Organization $Organization -PassThru
# If the -Organization parameter was NOT set, the $Organization variable will have a length of 0. Thus the if-condition does not apply, thus we do the else block
else
# Tell the user you are starting
Write-Host "Starting to create the user account for $GivenName $Surname"
# Create new User
$NewUser = New-ADUser -Surname $Surname -GivenName $GivenName -DisplayName "$Surname, $GivenName" -SamAccountName "$GivenName.$Surename" -Name "$Surename, $GivenName" -PassThru
# Tell the user you are copying Group Memberships
Write-Host "Copying the group-memberhips of $Template to $GivenName $Surname"
# Copy from old User
$NewUser | Add-ADPrincipalGroupMembership -MemberOf (Get-ADPrincipalGroupMembership $Template | Where { $_.Name -ne 'Domain Users' })
# Do Whatever else you feel like doing
There! Now we first check whether the -Organization parameter was set (it's not mandatory after all, so you can skip it). If it
was set, do whatever is in the curly braces after if (...). However, if it wasn't set, do whatever is in the curly braces after
else.
And that concludes my "minor" (and hopefully helpful) tutorial on how to use the function husk I posted :)
With this, whenever you find another cool command that helps you in the user creation process, you can simply add it, similar to what I did in these examples.
And if it all didn't make much sense, go through the tutorials in proper order and come back - it'll make much more sense then.
Cheers and good luck with PowerShell,
Fred
There's no place like 127.0.0.1

Why does moving the mouse over an IMAQ image display slow the GUI down so much?

I have a large application with several vi's running simultaneously under labview 8.6.1. When I mouse over an image display control in one of the vi's, everything slows down a shocking amount in all the other vi's. The windows task manager does not show a large increase in CPU use. My pc is has a quad cpu with 4GB of RAM, and the CPU and memory loads do not appear to be terribly taxing to the system. However, many of my vi's apparently come almost to a standstill if I just move the mouse in a circle around my image control.
This looks like it is largely a GUI display issue. If I make a new vi and put a while loop in it that only displays the iteration loop number to an indicator, I can see the iterating occurring, then stopping totally when I mouse inside the image display control. When I stop moving the mouse inside the control, or when I move it outside the control, the interation loop number jumps up, as if it had been incrementing behind the scenes the whole time. So only display of the interating was halted.
This problem occurs even if the vi with the image control is not executing. If the vi with the image control is open but not running, and I mouse over the image on it, the other guis all come to a screeching halt.
Does mousing in the image display control really utterly crush all other guis in all other labview windows? Is this an issue inherent to the image display control? If so, is there anything I can do about this?
Also, this issue is not entirely limited to display. I started looking at it in greater detail because this issue also exposed what I think is a race condition in my code. I have a vi that acquires an image from a ccd and puts it into an IMAQ image.ctl. This image then gets passed up to a vi up the call chain, and is put on a queue and sent over to be de-queued by a vi that has the image display control. Here's the kicker: when I mouse over the image display control, the image successfully gets acquired inside the subvi, and if I probe the wire leading to the output IMAQ image display.ctl, I see the image. If I simultaneously probe the wire coming out of the subvi one level up the call chain, the image gets lost about half the time. This only happens if I am mousing in the image display control IN A TOTALLY DIFFERENT AND SEPARATE VI. If I bump up the priority of the ccd image acquisition vi to 'highest priority', the problem only happens about 1% of the time, and I really have to mouse around to make it happen. Still, it's disturbing that mousing in the GUI in one window results in a failure of a separate subvi to simply pass an image up the call chain. I understand that IMAQ images are referenced rather than passed by value, but I don't see why there should be a failure to pass the image up the call chain. I've looked for a race condition, but can't find one.

I have finally been able to replicate the behavior that you are seeing on another computer once the image was large enough. Here are a few notes about this behavior:
First. The UI only slows down when the images are large, 16 bit images. The reason why this is unique to 16 bit images is that they can only be displayed on the front panel as 8 bit images. The workaround that Weiyuan suggested to change the 16 bit display mapping hints towards the root of the problem...that any time a mouse runs over the indicator, Windows asks the entire image to re-draw (having a separate indicator overlapping the image will create the same behavior). With a 16 bit image, not only does the image have to re-draw on the screen but the 16 bit pixels need to be mapped to 8 bits. When setting the 16 bit display mapping to Full Dynamic, this requires mor computation/pixel than 90% dynamic or one of the other mapping schemes.
This is expected behavior if your program is running and you're trying to display a large 16 bit image. To fix this behavior there are a couple options:
Change the 16 bit display mapping to something other than full dynamic. You can choose which 8 bits to display or if you want to map the bits.
Resize the image just for viewing purposes on your front panel (since you aren't going to view every single pixel of you image on the screen). You can use the IMAQ Resample.vi to do this. This will allow you to take your 1500x1500 pixel image and only display a 500x500 pixel version.
If you are interested in viewing small details of the large image, consider just displaying a smaller region of interest at a time.
Let me know if any of these solutions work for you. Good luck on your application.

Specify the GUI declaratively in ActionScript like in JavaFX Script instead of MXML

After reading a bit about JavaFX Script (which is actually remarkebly close to ActionScript 3) as a developer I thought the way one can specify the GUI declaratively in JavaFX Script via JSON-like notation for the components is pretty cool. It would be nice to have something like that in Flex/ActionScript too. The advantages I see over MXML are:
1) a more compact notation than XML which is nice from a developers view point who actually writes this kind of code. Of course the idea would be that designers still design the GUI with graphical tools that generate this code but if you have to dive in and edit the code it's nice not to have to deal with verbose XML and I think even designers can easily understand JSON-like code; don't just assume that designers love XML because HTML was based on SGML! I'm not so sure if today many designers really still know raw HTML that well (like in 1997, the early days...). Server side developers probably know it better because they have to adapt it to jsp or asp or whatever framework.
2) The fact that it's all ActionScript gives a seamless integration between just composing the components to form the GUI and adding scripts to add additionial behavior instead of mixing XML with actionscript code => no more need for those nasty CDATA blocks! It would also be easy for development tools like Flexbuilder to give a seamsless experience with code completion and zooming in on the code because it's all Actionscript! There's also no need for a separate expression language to tie the MXML to the underlying Actionscript. It would it also make easier to create custom components (not just simple composition components which is really easy in MXML) because you don't have to implement separate XML tags.
here's a short JavaFX Script example:
Frame {
content: GroupPanel {
var myRow = Row { alignment: BASELINE }
var label_col = Column { alignment: TRAILING }
var field_col = Column { alignment: LEADING }
rows: [myRow]
columns: [label_col, field_col]
content:
[SimpleLabel {
row: myRow
column: label_col
text: "Type your text here:"
TextField {
row: myRow
column: field_col
columns: 50
visible: true
Note that this shouldn't be confused with programmatically specifying the GUI in Actionscript (which is possible today as an alternative to MXML). What I propose is at a (slightly) higher level: you don't give a detailed sequence of methods/functions to call to construct the GUI (i.e. HOW to do it) but just specify WHAT you want.
Hopefully some Adobe Flex will see this and think about it. Although I think MXML is not too bad and I can live with it if I have to ;)

I like that idea Sean. A standard and well-supported way to separate MXML and code would be good. I'd love to have builder support a MVC style triad for MXML files, with the
model.as being simply an all-public-all-bindable class full of VOs and view-specific information, any view-manipulation and view<->app communications in the
controller.as, and nothing but bindings and layour in the MXML. There's (almost) nothing stopping you doing this by hand at the moment, but it's a pain, and developers wouldn't stick to it for very long, when they need to create and maintain 3 separate files for that simple "error dialog" without a hand from Builder.
Then again, I'd rather Adobe spent the time that would take on opening and better-documenting builder's APIs, so we can write our own plugins easily, but that's my greedy side- A standard builder-supported MVC pattern for custom MXML components would be aweseome for people that aren't me :)

As for JavaFX, I don't care for it.

Jason you bring up a good point on a concept that I think Adobe should
poach from a different framework, Silverlight. In Silverlight the
code-behind pattern is automatic and very nice to work with. Every
interface can be composed of both a layout file and a script file, and
they get composited into the SAME class at compile time. So you can
have both a FileDialog.mxml and FileDialog.as file that know about each
other automatically, without the need to subclass one from the other.

Personally, I like the separation between the MXML and ActionScript.
We're working on a large project, and so we have all the ActionScript
separate from the MXML files. For example we'll have something like
filedialoglayout.mxml, and then
filedialog.as that is a subclass of
filedialoglayout. All event handlers and the like are setup in the
filedialog.as file - the mxml file doesn't know about any function names.
Advantages:
MXML files become layout only - and are more easily shared and worked on
with non-technical people
ActionScript is all in *.as files: no CDATA blocks and no FlexBuilder
quirks where editing ActionScript inside a CDATA block doesn't work
quite like in a real AS file.
For simple experiments, and for learning, it's obviously nice to have
everything in one mxml file, but in a big project like ours, the
separation helps keep things clearer and more maintainable.
Why use the mxml at all? The MXML files are nice to edit with the
visual editor in Flex Builder, and it's much easier to apply styles and
embed assets in MXML than it is in pure ActionScript.
I think two ways to talk about the same thing (XML and ActionScript) is
already almost one too many - adding a third (JSON) would really be too
much.
Just my thoughts.

This reminds me of a certain workflow pattern that has emerged for us
which might help provide some insight on this topic. I'm working on a
project with a couple other developers which connects to a webservice
for supplying clientside data. This data is available in both json
notation and xml notation. The thing is, while the developers have
overwhelmingly agreed that we should be consuming the json version
since it can be parsed faster and provide more meaningful context for
objects (ie strings vs ints vs arrays etc...), all these same
developers rely exclusively on the xml notation when asking questions
about the data or passing structures around to discuss.
I see the same thing when looking at JavaFX and MXML. JavaFX might
allow for more accurate structures and might be able to be compiled
faster, but MXML is better for being self documenting even if it
requires more verbosity.

I'd be curious what other people think. I see MXML as a distinct
advantage over doing the pseudo-script stuff. I really don't like
the JavaFX system actually.

How to modify the search results of the GUI for subscribing to calendars

How to modify the search results of the GUI for subscribing to calendars
Note:
<OL>
<LI>The following information applies only to iPlanet Calendar Server 5.0
Patch 3.
<LI>All of the cases for which the XSLT changes will work have not been
verified.
<LI>The following is only an example of an XSLT customization.
</OL>
The example below shows a sample customization of the
search_for_calendars
dialog. This customization will result in the Display Name being included as
part of the search results in the GUI, which would normally show just the
calendar ID. It will render the returned calendars in the following format:
<P>
Display Name - <I>description</I>
<P>
Normally, the format would be as follows:
<P>
Calendar-ID - <I>description</I>
<P>
</A>
The example consists of the following two files:
<P>
<OL>
<LI>search_for_calendars_common.xsl
(the entire XSLT file)

How to see the GUI of the guest os ?

Hello all,
I have installed the oracle linux 5 as the guest OS using the PVM template.
I can access the the guest console using the vm manager / vncviewer, but its just the console.
1]What should i do, if i want the GUI (x server). (In /etc/inittab, its 5.) ?
TIA,
JJ

The PVM guest templates that are provided by Oracle do not have the full X system installed, so even though inittab is set to 5, the GUI will not start. You would need to install the GNOME Desktop group before the GUI will work.
However, once you do have it installed, or if you do a manual installation of OEL5 from a DVD, the VNC viewer will show you the GUI.

Displaying in the GUI from another called class

Hi,
New to creating GUIs in java and I'm having two problems:
1- How do I display several images in my GUI in different areas of the GUI window?
2- For these images and my text boxes, how do I display things when it's not the class the GUI was created in, but another class that is called by the main? Basically, my main initializes my GUI and then calls another class that does all of the actual work in the program, but I need to display text and images that are being manipulated in those classes.
Sorry for the long-winded questions and thanks for any help that anyone can provide.

You might want to start out by looking at the demo Swing applications to study how they work. These are part of your JDK install under $JAVA_HOME/demo/jfc
Also keep in mind that all calls to directly manipulate the Swing UI after it is mapped on the screen need to take place on the event thread. For more information on this, take a look at:
http://java.sun.com/products/jfc/tsc/articles/threads/threads3.html
http://java.sun.com/docs/books/tutorial/ui/swing/threads.html

How to get Solaris 10 to boot from the CLI instead of the GUI?

I tried searching on the site but was unable to get useful information from setting up Solaris such that it boots to command prompt instead of the GUI. Any help or suggestions would be appreciated.

This will also work if you're running out-of-the box Solaris 10:
svcadm disable graphical-login/cde-login:defaultThe problem with doing it that way is you then can't use your Solaris host to run SunRay thin clients. If you need to use the box as a SunRay server, you'll have to remove the reference to the :0 display somewhere in /etc/dt/config/Xconfig, IIRC.

Setting multiple text dynamically on the GUI

HI,
I have this function which computes the position record of 6 requests. ( ie x,y,dx,dy--these are the position records for a request)
I want to display these position records in a textfield, which i have in my GUI, as soon as i press the "positionrecord" button.
I am able to print the position records for all 6 requests on the console(of eclipse), but on the GUI only the position record of the 6th request is getting displayed in the textfield.
I have been advised by mny to use paint() and repaint() functions for this but no one has been able to give me a concrete solution as yet.
I also need to produce a delay of 1 sec between the position record being displayed in the textfield on the GUI, for which I have used a delay function. THE ONLY PROBLEM IS I AM NOT ABLE TO DISPLAY THE POSITION RECORDS FOR ALL THE 6 REQUESTS ON THE GUI DYNAMICALLY.
Please can anyone help me on this.
I have posted part of my code below. I have put the paint function also but i am not at all sure if it is correct.
Thanks in advance.
warm regards---
public void paint() {
Graphics g= null;
PosRecord prec=requestGenerator.getNextRecord();
Graphics2D g2 = (Graphics2D)g;
double x = 15, y = 50, w = 70, h = 70;
SidePanel.PositionRecc.setText(prec.toString());
MainFrame.mapPanel.repaint();
Ellipse2D e = new Ellipse2D.Double(x, y, w, h);
GradientPaint gp = new GradientPaint(75, 75, Color.white,
95, 95, Color.gray, true);
e.setFrame(x 200, y, w, h);
System.out.println("inside paint function");
if(buffer != null)
bgraphics = buffer.getGraphics();
Graphics2D g2d = (Graphics2D) bgraphics;
if (request.getId()==100) {
System.out.println("Anonmized for message of node id " request.getId() );
System.out.println("Grid Cells: "); //request.getId()
for (int i = 0; i < orequests.size(); i++) {
SidePanel.PositionRecc.setText(request.toString());
paint();
SidePanel.PositionRecc.isOpaque();
System.out.println("NEW");
isVisible();
//MainFrame.mapPanel.repaint();
try
Thread.sleep(100);
catch(InterruptedException e)
//e.printStackTrace();
//super.update(g);
SidePanel.PositionRecc.setText(request.toString());
MainFrame.mapPanel.repaint();
// TraceGenerator.SidePanel.PositionRecc.setText(request.toString());
System.out.print("NEW1 " + orequests.get(i));
}

I had posted it on the wrong forumAnd you still posted in the wrong forum. In the future, Swing related questions should be posted in the Swing form.
The problem is you are blocking the EDT. Read the section from the Swing tutorial on Concurrency for an explanation about what this is and how it works.
I also need to produce a delay of 1 sec between the position record being displayed in the textfieldThe solution is to use a Swing Timer. The code will be executed on the EDT so it will work just as you want. The Swing tutorial also has a section on "How to Use Timers".

Updating the GUI from a background Thread: Platform.Runlater() Vs Tasks

Hi Everyone,
Hereby I would like to ask if anyone can enlighten me on the best practice for concurency with JAVAFX2. More precisely, if one has to update a Gui from a background Thread what should be the appropriate approach.
I further explain my though:
I have window with a text box in it and i receive some message on my network on the background, hence i want to update the scrolling textbox of my window with the incoming message. In that scenario what is the best appraoch.
1- Shall i implement my my message receiver as thread in which i would then use a platform.RunLater() ?
2- Or shall i use a Task ? In that case, which public property of the task shall take the message that i receive ? Are property of the task only those already defined, or any public property defined in subclass can be used to be binded in the graphical thread ?
In general i would like to understand, what is the logic behind each method ?
My understanding here, is that task property are only meant to update the gui with respect to the status of the task. However updating the Gui about information of change that have occured on the data model, requires Platform.RunLater to be used.

Shall i implement my my message receiver as thread in which i would then use a platform.RunLater() ?Yes.
Or shall i use a Task ?No.
what is the logic behind each method?A general rule of thumb:
a) If the operation is initiated by the client (e.g. fetch data from a server), use a Task for a one-off process (or a Service for a repeated process):
- the extra facilities of a Task such as easier implementation of thread safety, work done and message properties, etc. are usually needed in this case.
b) If the operation is initiated by the server (e.g. push data to the client), use Platform.runLater:
- spin up a standard thread to listen for data (your network communication library will probably do this anyway) and to communicate results back to your UI.
- likely you don't need the additional overhead and facilities of a Task in this case.
Tasks and Platform.runLater are not mutually exclusive. For example if you want to update your GUI based on a partial result from an in-process task, then you can create the task and in the Task's call method, use a Platform.runLater to update the GUI as the task is executing. That's kind of a more advanced use-case and is documented in the Task documentation as "A Task Which Returns Partial Results" http://docs.oracle.com/javafx/2/api/javafx/concurrent/Task.html

RFC for log settings in the GUI for stats

We've used a variety of stats packages for the virtual hosts we support. A few customers prefer this service, and some want to have their own stats available (the majority don't care). So this is a question about log management. We try to let the GUI in 10.5 manage as much as possible (for in-house admin needs, as well as the expectation that Apple's GUI needs to be tested to tell the Server Group where the hiccups are and missing features ought to be.
What would you recommend as a default setting for access and error logs? Dump all into the default common logs, and roll them every 7/14/30 days? Let the stats packages process and divide out for sharing with clients when those cron jobs kick in?
or always split out the logs separately into each VH home, and process separately?
What workflow functions best in your opinion?

This brings to mind another question (don't they all?)... and why I'm hoping for more documentation on the manner in which logs are managed and rolled in the SA interface.
If all logs were stored in the one monster log file set (access/error), and subsequently were set to be rolled at 7 days, when is this actually triggered? Is there a hard-coded time, or just whenever each setting was changed as the starting point. (One wonders if the log rolling occurs precisely at the point in which the command was invoked or is it at 2 a.m. for the appropriate day in question?)
And if all logs were not split out, is there a mechanism by which the default access/error logs could be rolled. Our stats package can split out VH entries properly. so that wouldn't be a problem.
I can easily see where a log policy needs to be established early on to preclude such issues, but knowing the behavior of the log rolling and cron jobs invoked by the SA would be really helpful.

CF 902 hotfixes, is the GUI needed?
