Package Beginner Question

Hi guys. i have an app(bankingApp.class) which uses an abstract class(Account.class) and its subclasses(Savings, Checking...etc) to process them. They work fine now in the default pacakge, but i am now trying to put the app in the default package and the others in a banking package. How do i do that?
Read the tut, but dun really understand. are packages also subdirectories?
Really appreciate the help!

This answer simply is wrong. And I disagree with that.
Although there is not much functionality with directories I can for instance do the following
cd ..
This moves up one directory level. This implies that one directory is 'aware' that is a child of another directory.
In java there is no behavioural differences when one package is the 'child' of another.
The most common problem with this misconception in java is in the presumption that a child or parent package should have access rights to another package because of the hierarchial nature. And that is not true.
So the answer is YES, packages also are SUBDIRECTORIES.Once again no they are not.
The jar tool uses the hierarchial nature of directories so it can create the correct naming in the zip/jar file. However, that does not mean they are the same.
Another example. A parent directory 'contains' a child directory. If you delete the parent the child is gone. That is not true in java.
Packages too. So what? Packages are used to organize java classes in packages and subpackages.
NO. That is simply not true. Package names are completely independent of each other. There is no such thing as a subpackage. There are are absolutely no behavioral differences between a subpackage and any other package. All that matters is that the packages are different. Nor is there containment.
Want an example for subpackage that is linked to its
superpackage? Take javax.swing.table, which bases upon
a Class JTable which lies in package javax.swing.Perhaps you are pointing to a conceptual rather than behaviour difference.
Being a little more specific
javax.swing.table.JTableHeader is derived from javax.swing.JComponent. But behaviorally it could be derived from XXX.JComponent and it would make no difference.
However, it might make sense in your head to think of it as being a child. But that doesn't mean there are any behavioral differences.
BTW: To use your words, each directory is separate from every other directory, too!Nope. As I pointed out. There are behavioral implications. If I delete a parent the child goes away. I can only get to the child by accessing the parent (because of containment.) I can move up to the parent from within the child.
Behavior of what? Of the java program,
of the java compiler, of the java VM?Well specifically the JVM and the java compiler.
A .jar is still a (more or less simple) file archive, ...Yes, but that has nothing to do with the behavior of java.

Beginner question: Configure Tomcat for JAAS?

Hi,
This is a beginner question :-(. I'm trying to get JAAS to work on my Tomcat (6.0.12) installation. I used code from a Javaworld article (http://www.javaworld.com/javaworld/jw-09-2002/jw-0913-jaas.html)
Of course I had to configure my Tomcat to work together with JAAS. The document I used is: http://tomcat.apache.org/tomcat-6.0-doc/printer/realm-howto.html
According to the Tomcat doc I have to do the following steps before I can use JAAS to authenticate a user:
1. Develop your code. Place the compiled classes in Tomcat's classpath
2. Setup a login.config file for Java, and tell Tomcat where to find it (set JAVA_OPTS)
3. Configure the JAASRealm in your server.xml
1 Develop code: I use the following classes:
PassiveCallbackHandler.java
RdbmsCredential.java
RdbmsLoginModule.java
RdbmsPrincipal.java
These classes I put in the package rdbmsjaas.
In the %CATALINA_HOME%/webapps/Javaworld_Jaas/WEB-INF/lib directory I created the rdbmsjaas.jar file.
The jsp is called jaas.jsp, and is stored in %CATALINA_HOME%/webapps/Javaworld_Jaas
2. Setup login.config
In %CATALINA_HOME%\conf I saved the file Javaworld_all_that_Jaas.config, containing:
Example {
   RdbmsLoginModule required
   debug="true"
   url="jdbc:mysql://localhost/jaasdb?user=javauser&password=javadude"
   driver="com.mysql.jdbc.Driver";
};I created an XP Environment Variable JAVA_OPTS with the value <-DJAVA_OPTS=-Djava.security.auth.login.config==C:/Program Files/Apache Software Foundation/Tomcat 6.0/conf/JavaWorld_All_That_Jaas.config> (excluding < and >)
I used the fully qualified address, instead of $CATALINA_HOME/conf/JavaWorld_All_That_Jaas.config. I think XP balks when it sees $CATALINA_HOME).
3 Configure JAASRealm in server.xml
In %CATALINA_HOME%\conf\ I changed web.xml. I added the following lines:
      <Realm className="org.apache.catalina.realm.JAASRealm"
             appName="jaas"
             userClassName="rdbmsjaas.RdbmsPrincipal"
             debug="99"
       />If I run the jsp from http://localhost:8080/JavaWorld_Jaas/jaas.jsp, I can enter my username/password, but when I click the Submit button, I get:
Caught Exception: java.lang.SecurityException: Unable to locate a login configurationWhere did my configuration go wrong?
Abel

You will need a JSP/servlet engine such as Tomcat - Apache alone won't do it.
I haven't seen any tutorials on set-up but the Tomcat documentation includes info on how to link to Apache. There are also books you can buy - check out the online book stores such as Amazon.
There's also a lot of info on this forum.

Beginner Question

Hello all, hopefully I have posted this to the correct LiveCycle board!
I'm new to Acrobat and LiveCycle in general. I'm working out of windows LiveCycle Designer 8.x and my question is as follows....
I'm working off of the "Quote" Form Template and what I am looking for is a way to make the rows of the Table expand as needed. I will be converting this Template into a "Purchase Order" form, and there will be many occassions where I will need to increase the table rows - perhaps onto a second or even third page - due to the volume of different items I will be seeking prices on at a given time.
Long story short I would like to take this "QUOTE" form template and make it such that if needed, I can expand the table size one row at a time, pushing the content beneath (Comments, subtotal, etc) onto the next page....
Hoping I have explained my query well enough, Could anyone provide me a solution or point me in the correct direction?
Many thanks!

As a followup, so as not to clog the board with numerous threads I have another beginner question
For the sake of hypotheticals I am creating a dynamic PDF form. This pdf is a Purchase Order Form, with a table in the Body that will expand/contract as the form user needs. (EXA- Default table size is 5 items, however user is creating an order for 12 items, he/she can increase the table rows to desired capactiy.) It will be a very simple layout. All data for the form will come from manual entry, no XML data binding going on.
My new question is as follows:    Is there a way I can have this user's Adobe reader or Adobe acrobat software remember previous data entries, so that if 4 weeks after ordering widget X he/she needs to place another order for widget X, the software will autofill the table as he/she types into the table cell?
This would be similar to how Excel will start to autofill if it recognizes a previously entered value from some other cell in the worksheet (workbook?)
EXA-
[NAME]   [MODEL]   [QTY]   [PRICE]
Widget           A            433        $30.00
Would it be possible for the software to notice that I'm typing the word "widget" somewhere after typing "wid" ???
Many thanks for any and all followups, I'm a teenager trying to help out in my father's small business. They are in the darkages here and I'm doing my best to self teach.
Thanks.

Beginner question: Can I apply one formula to all cells in a column?

Hi,
I'm new to spreadsheets, so apologies for asking what is probably a very simple question.
I want to apply a formula that divides the values in one column (W) by values in another (AX) for a table containing 3000 rows, and outputs the result for each row into the appropriate cell in the new column I've created.
Numbers 09 'help' hasn't helped to this point.
Thanks in advance for any assistance.

Besides Numbers '09 Help there are two other useful resources available in the Help menu: the Numbers '09 User Guide and iWork Formulas and Functions Help.
For "Beginner questions," my first choice would be the User Guide. For the specific question you asked, a quick scan of the chapter on "Using Formulas and Functions" (pp 83-96) will provide some useful information. Start in the neighborhood of page 93.

Beginner question regarding 32-bit mixing and mixdown workflow

Hello
I have a beginner question regarding 32-bit mixing and mixdown.
If I edit some 16Bit, 44.1kHz Stereo WAV Files and put them into multi-track view to do crossfades, how should I do the mixdown?
Audition shows me in multi-track view, that it is doing 32-Bit mixing.
Can I just mixdown to 16Bit, 44.1kHz Stereo without any dithering (as the files are 16Bit, 44.1kHz Stereo to begin with), or will I lose quality that way?
I will be performing a normalization to 96% to the mixdown and then split to tracks in Audition, as in the end I want to to have an audio CD.
I guess I could mixdown to 32Bit, then normalize and in the end save back to 16Bit, 44.1kHz Stereo WAV (with dithering, I suppose?), but I want to avoid any unnecessary converting steps.
Greetings

Any time you do any processing on a 16bit file in 16 bit only it will degrade the audio slightly due to rounding of the calculations. Working in 32 bit floating point (Audition's default) takes account of all bits generated due to processing.
So it is always best to work in 32 bit, even if your originals were 16, all the way through until the last stage of saving the files for CD burning. Any losses due to conversion will be insignificant against those due to working 16 bit.

Beginner question - how to efficiently check if a photo is part of the selection

Dear all,
Sorry for this beginner question, however I don't know how to solve it and I'm sure that there is a quick and easy answer to this:
My target is to get all the "heads of stack" (photos with Position 1 in stacks) of the selection ("photos" below).
for i, photo in ipairs( photos ) do
local photoName = photo:getFormattedMetadata('fileName')
   if photo:getRawMetadata( 'isInStackInFolder' ) then
   --Photo is in a stack
        local photoHeadOfStack = photo:getRawMetadata('topOfStackInFolderContainingPhoto')
        local stackPos = photo:getRawMetadata( 'stackPositionInFolder' ) -- get the position in the stack
        local photoHeadName = photoHeadOfStack:getFormattedMetadata('fileName')
        app:logVerbose("Photo nb ^1, name ^2 is in a stack with the position ^3", i, photoName, stackPos)
        if stackPos == 1 then
        -- photo is master of the stack
             stackTop[#stackTop+1]=photo
             app:logVerbose("Photo ^1 is top of the stack ^2", photoName, #stackTop)
             -- check if couple if correct
        elseif photos.photoHeadOfStack then
             app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack already selected", photoName)
        else
             stackTop[#stackTop+1]=photoHeadOfStack
             app:logVerbose("Photo ^1 is in a stack, but not on top. Top of the stack ^2 - ^3 ", photoName, #stackTop, photoHeadName)
        end
end
end
In the if structure in the middle checking the Position in the stack, if the Position is not 1, I would like to check if the photo heading the stack ('photoHeadOfStack') is part of 'photos'. I tried 'elseif photos.photoHeadOfStack then' and 'elseif photos[photoHeadOfStack] then' but it doesn't work ->this elseif is never true even if 'photoHeadOfStack' is part of 'photos'.
Is there anyway to have this check done without checking "manually" photos ?(via for example a for Loop)
I'm sure that Lua proposes this, but I don't know how...
I thank you for your Support!

    --[[ This code creates "stackTops", an array of LrPhotos that are the
    tops of all the stacks containing photos in the array
    "photos". ]]
stackTopSet = {}
for _, photo in ipairs (photos) do
    local stackTop = photo:getRawMetadata ("topOfStackInFolderContainingPhoto")
    if stackTop ~= nil then stackTopSet [stackTop] = true end
    end
stackTops = {}
for photo, _ in pairs (stackTopSet) do table.insert (stackTops, photo) end

Beginner Question: SA520 Admin access through WAN port

Dear all,
I've a beginner question regarding my brand new SA520: How can I configure the box so that I'm able to access the admin GUI not only through the LAN ports but also from the WAN ports?
I tried already to allow inbound traffic to the firewall's internal IP address (not sure if done right, so) and granted the admin user access profile from WAN and LAN: I can access the box from the LAN but not from the WAN. Any ideas?
Thanks,
Eric
PS: Yupp, I know that it's not a good idea to expose a FW admin GUI to the WAN - but this is only a lab environment

Go to Administration -> Users.
click on the 'Edit User Policies' 'Login' button. It's there you can enable WAN access.

Beginner question - using pre for flexibility in text?

Hi,
Apologies for the beginner question, but I am struggling to work out whether it is more sensible to use <pre> in all my texts, as it seems more flexible.
It seems that when I use <p> - paragraph - I can't use multiple space bars to align certain bits of text, but more disruptively I have gaps between text when I press Enter (I guess this defines the paragraph, but isn't always wanted).
Well, basically, <pre> seems more flexible, but it behaves strangely sometimes. What do other people use?
Many thanks!
Ivan Reshetilov
http://www.ivanreshetilov.co.uk

Hi Ireshe, just a beginner like you. Have never heard of <pre> tags, use <p> tags. If you hit SHIFT enter after a sentence this puts in a <br> tag or line break which basically leaves a blank line between text.
If you add     &nsbp;    or lots of them between words this gives you an extra space between letters. How all your paragraphs sit on the page is defined by CSS. E.g.
p {
     margin:0;
     padding: 5px 0 0 10px;}
This would place all text within <p> tags on your page, with a 5px gap at the top, no space to the right or bottom and 10px space to the left. Hope this helps, good luck!

Beginner question: creating my own virtual instruments from samples

Hi, I have a beginner question. I'd like to make a click-track, but I want to use my own sounds, either recorded or from the internet. Can I do this with Logic Express 7, or do I need Logic Pro 7 and the EXS24?
Thanks,
Ryan

I think you can do it, but it might be a pain.
You could import a sample of a single click and just paste it into every beat on the Arrange Page.
Other than that, you might need the sampler included with Logic Pro

FIOS TV/DVR beginner questions

I'm a long time Dish subscriber that is considering switching after 10 years to FIOS TV, but after looking around at other forums, reading the scant info that I can find on the various Verizon sites, and reading the Motorola 7200 DVR manual - I still have a bunch of questions that I'm hoping some of you could answer so that myself and others can make an informed decision. I've got the FIOS internet and am very happy with the 20/5 service - its solid as a rock and fast as greased lightning.
Signal My Dish HD is quite compressed, and prone to lots of pixelation, yellow screens, and audio drops - and also free of charge you get a loud pop whenever the channel changes from SD to HD signal, along with the unavoidable volume differences between stereo and Dolby 5.1 audio when the signal goes HD to SD. I'm aware that most reviews indicate that the FIOS HD picture quality is hard to beat, but I'm wondering about the various audio and video problems and whether to expect a couple of dozen instances per hour show like I tolerage now on Dish? A great picture most of the time can still be ruined by a bunch of audio drops or 5 seconds of yellow screen every half hour. Does internet computer usage deteriorate the FIOS TV signal if you have a couple of computer users on-line while viewing or recording TV?
Content Dish has a 100 HD channels, FIOS in my area (Portland) has around 100 HD channels, with over 90% overlap. Dish has NBAtv, Fox Sports HD, CBC-college, and ESPNWS while FIOS has Big 10, ESPNU, and more of the movie channels in HD. The big difference seems to be VOD, but I can't find any comprehensive info on it. The Verizon website boasts of 11,000 monthly titles (8500 free), but you have to have some sort of user password to see the VOD choices on-line. I don't get the "monthly" thing either, seems like it would just be a growing VOD library that accumulates more titles, but the monthly thing makes it sound like some stuff disappears from VOD over time. Does the free VOD includes the recent movies, etc. or is all that stuff Pay per View and the free stuff is all kickboxing and fishing shows? Does anyone have a way for a non-FIOS TV subscriber to get a look at the list? The Verizon site just shows you a couple of titles and doesn't say whether they are free or PPV so it is hard to figure out whether VOD is something that I would use or not.
DVR's I currently have a 60 hour HD triple tuner ( 2 SAT, one OTA) Dish DVR (722) that I think is considered one of the better ones available. Besides the large hard drive, the unit also has a USB port that you can hang another 500G external hard drive off of after a $35 activation fee. I understand that FIOS is not allowed to do the same thing with their DVR's because of the copyright issues with the content being carried over wires instead of beamed from a satellite, although some things I read indicated that it still may be something they enable at some point. The other big difference is that the Dish DVR has all the outputs "hot" at the same time - meaning you can drive a bunch of TV's, SD and HD, simultaneously. I drive one SD signal 300 feet and a second HD signal 100 feet. I know the Motorola units that FIOS leases can only output one port at a time.
I read through the manual for the HD DVR (Motorola 7200) but Verizon lists the same manual for the "Home Media" DVR (Motorola 7216) so I can't tell what the real differences are between the DVR offerings.
In order to watch recorded or live shows on more than one TV - do you have to have a box (STB) per TV, whether using the Home Media DVR or the regular HD DVR?
Is the VOD content only available via the Home Media DVR, not the regular DVR? Is the only other main difference between DVRs the remote DVR functionality (internet programming)? I know there are some other multi-media things, pictures and music, but I'm focusing on TV. I don't get how FIOS can call the Home Media DVR "multi-room" if you still need a STB for other TV's, isn't that the same whether using a regular DVR or the Home Media DVR? Does anyone have a link to the actual 7216 manual?
How easy is it to change the output port? Is it a quick software change? My thinking is that if I hooked up a TV to HDMI, another to component, and maybe one to SD - how clunky is it to switch the output so that someone could watch TV1,2 or 3 (one at a time, of course). I'm also assuming that the audio ports will all work simultaneously so that one could send the video to HDMI, for example, and the audio to a receiver. So I think its only the video that is limited to a single output.
Does either DVR have an Over the Air digital antenna input?
Is the remote control RF or IR? Does it have the all important 30 second Forward skip button and 10 second Back skip button?
How long is the guide, a week, 2 weeks, etc?
I couldn't find much in either the manuals or the verizon website about the Interactive Media Guide. Is the VOD included in search functions? Are there TIVO like "season passes" and the ability to find and record new episodes of a show, etc.?
Are there any good reviews of the DVRs, the Interactive Media Guide, or something with more detail than Verizon's sketchy descriptions or the lousy 7200 manual?
I realize a lot of my DVR questions could be answered by proper documentation on the 7216 and the Interactive Media guide, so if someone has a link to detailed info on these items, it would be much appreciated.
Thanks for any help you can provide. I've spent a lot of time and effort getting my Dish system all figured out and the way I like it, but the quality issues and cost have me exploring options.

Does FIOS internet usage affect FIOS TV signal quality? (I have 20/5 service). Negative. The FiOS signal itself is only affected by physical damage and or equipment failure on our network equipment. Now if you you are talking inside of your house signal(there is a difference). VOD on FiOS is a strictly data service and is very bandwidth intensive due to the large size of the file itself. That is why we recommend you only watch one HDVOD at a time as the MOCA network in your house can't really handle two running at the same time with 100% QoS. So if I understand you correctly, VOD could be affected by heavy home network useage (or simultaneous VOD requests) but DVR recordings or live TVnot, or just less likely? That is correct. VOD services can be affected by heavy home data network useage. The live TV and subsequent recordings made of the liveTV to a DVR will not be affected by heavy home network useage.
Are there any futher plans for external hard drives and/or the HD DVR's to talk with each other? My manager has informed we are actively researching a solution to this problem. When or if anything will come of the research has yet to be seen.
How hard is it to switch outputs on the DVR (I'm assuming it is a software menu change)? Could it be programmed into a learning remote (keystroke macro) so that you hit one button for TV1, another for TV2, etc.? Last time i checked this was IMG 1.3. At that time all of the outputs were consistently on. There is no switching the output like there is switching a tuner on a TiVO. When i tested this in my video lab i hooked up a QIP6416 via HDMI and Component. Each output would show the same channel on either input ont the TV. Each output will only display whatever channel you have the STB currently tuned to. If this is not what you mean feel free to correct me. That is what I mean, my current config is one DVR hooked to SD TV1 via cable, HD TV2 via HDMI, and HD TV3 via component - and all three get signal simultaneously. I was told by a FIOS tech that only one output is "hot" at a time on the FIOS DVR. I understand that you can't watch channel X on TV1 and channel Y on TV2 simultaneously, but I'm wondering if you can watch channel X on TV1,2, etc. I went and tested on our QIP6416 model and unfortunatly you cannot only one output is 'hot" at this stage of IMG releases. From the looks of it the outputs are in a heirarchy hdmi ->component->s-video->composite->RF.
Can the IR remotes be programmed to run just DVR1 or just DVR2 if you put two in the same room (i.e. different code set for remote 1 and remote 2)? I note about 4 different remotes shown on the FIOS website, does the HD DVR have RF capability or will only IR remotes work with it? No the FiOS remotes are pre-programmed to work on every single FiOS STB. You could take your FiOS remote to another FiOS user's home and control their STB. Makes for some interesting fun. But it is all IR, right? The DVR's won't accept an RF remote signal? It is all IR.
Can channels be locked out on the guide so you don't see them, both adult and ones that you just aren't interested in? If you can lock them out of the guide, does that mean they won't show up in searches as well? There is currently no way to remove channels from the normal guide. We used to support this feature with our old guide produced by microsoft but the feature was left out of IMG. We have given the option for customers to setup multiple channel lists in guide format under the favorites option. You can set the guide button to pull up the first of those lists instead of the guide itself. You can lock the channels out but the titles will still be readable by anyone looking.
The "Welcome kit" PDF talks about being able to resolve timer conflicts for series, but I assume you can also assign priority to one time events and/or access a general recording schedule where you can manually resolve conflicts as well. Is that correct? Does the recording automatically pad sporting events with extra time on the end or do you have to set that up manually with each sporting event? Yes our recording schedule does will recognize recording conflicts. There will be a marker on the program in the guide informing you of a recording problem. There is also a section in the menu of the dvr that will show you the entire recording schedule with any conflicts. Yes you can set priority to whatever you want. No we do not pad for sporting events. That is something you will have do manually. Unfortunatly i do not see this changing anytime soon as it appears to be a limitation of our current guide data producer.
No OTA tuner in any FIOS DVR, correct? Correct.
The VOD descriptions say movies are "rented for 24 hours", but on the VOD list it shows a lot of older movies for free on top of the TV series,sporting events, etc.. Are these all just previews or is there a good inventory of free movies? In all honesty the free VOD movie selections are pretty limited and most of them are independent flicks or trailers. As soon as our HD on demand library is at an acceptable volume i believe we will be working in improving this aspect of VOD. The subscription based movie packages is where it is at though. The movie packages have pretty sizeable libraries that you get access to for free with the packages. Personally, i am partial to the Showtime on demand library(lots of good series). Please keep in mind though that our VOD library will change very frequently. VOD content is provided to us by the network that wishes to put it up. They can also will us to take it down as well.
I'll probably think of a few more, but that's it for now.

Windows 8.1 official offline upgrade package & GPO question related to Metro & UAC

Hello!
I am testing pre-deployment of Windows 8.1 in our 2008R2 domain. So far only my workstation is upgraded to win8x64 (from win7x64) and I am assessing if all of our LOB aps and servers will work fine with it. A few questions
1. We use workstations coming with OEM win8 license (all currently running win7 downgrade). I noticed that oficially there is no win8.1 offline upgrade package! Does that mean that Microsoft officially wants people to sing into Windows Store with a Microsoft
account to perform online upgrade with administrative privileges? That's pretty awkward ...
I figured that I could use win 8.1 installer ISO/UFD that I created in past (for home computer actually), but am not sure if that works out with our win8 OEM license keys tied to BIOS/UEFI on each desktop computer.
Was actually expecting an 8.1 Service Pack package that I could publish to WSUS, so it could take care of upgrade on win8 computers, but there is no such thing ... and no official package for 8.1 offline deployment either ... weird ...
Currently I am actually about to upgrade my own/test workstation to 8.1 (from 8.0, using Windows Store online), then sysprep it and create a reference WIM image and see if I can deploy 8.1 thick image (with all updates and company apps installed) this way
via WDS. anybody tested if it works this way? any gotchas?
2. win8 GPOs
Can somebody enlighten me where in Group Policies I can find a setting to re-assign ALL file/media extensions (e.g. jpg, tiff, png, bmp, mp4, WMV, etc.) back to Desktop applications instead of the horrible Metro UI equivalents?
We are actually about to bypass Metro UI completely on each computer so it boots straight to desktop and all file upon double-click must open an application within Desktop (no Metro UI for end users).
I know how to do this manually one by one via Group Preferences, but am asking if there is some specific GPO ADMX setting that would replace Metro UI apps with Desktop application in any and all file associations.
Personally I see no point in using the clunky Metro UI without a touchscreen.
3. is UAC enabled required for Windows Store to work?
Seems like it needs at least the Low security setting, so the Windows Store and Metro UI stays operational. no workaround for that for disabled UAC environment?
Just asking, it's not a big deal, people can learn to live with UAC, but am curious if that's by design.
Thanks for answers!

Hi,
1. For upgrading to Win8.1, please refer the following link:
http://windows.microsoft.com/en-in/windows-8/update-from-windows-8-tutorial As I know, Win8 activated using KMS, cannot upgrade to Win8.1
2. No, there is no such GPO settings added into Admin template. You will have to work around this using GPP...
3. There is no way to bypass UAC and allow Windows Store at one time. UAC is headache since Vista times and we have to live with the Protection :) Believe me, it does good to PC safety.

Yeah, UAC is a bit of a headache especially with legacy software. When deploying our Win7 domain clients however I got away by simply disabling it to make it easier for all users coming straight from XP environment.
for future win8.1 deployments however, I will set the UAC level to Low and keep it there, so modern apps and winstore stays operational if anybody wanted it or needed it. not a big deal, plus an added security layer, I agree with that.
As per default win8 file extension associations ... well, that's a bummer, and yeah, the GPP is what I had in mind to work around that manually.
I am running on upgraded win8.1 right now and so far I like it more or less in work environment, after adjustments that is :)
My only problem is related to win 8.1 clean installation and imaging and deployment however, wanted to use Lite Touch via WDS for w8.1, but problem is that I have no image of win8.1 that can activate with OEM licenses tied to BIOS.
Sysprep doesn't work on upgraded 8.1 (from 8.0), so I can't image that with generalization and on other hand the only generalized image I can take is from bare win 8.0 without the 8.1 upgrade. What I mean is that our computer vendor (HP) switched to OEM
win8 licenses tied to UEFI/BIOS (no more case stickers) and that doesn't activate when I try to clean install 8.1 even though it should, but the build ID string in BIOS must be changed ... need to open a case with HP to work it out, I am sure it's still possible
to achieve even without volume licensing.
We use a Basic Infrastructure model so far with retail+OEM keys (no KMS so far but it's in plans if Office deployment plans get approved by CFO). I thought for 8.1 actually it was a good idea to implement Standardized Infrastructure with thick images, as
manual upgrade to win 8.1 from win 8.0 is painful.

Slackware user - Arch install process and package management questions

I currently am using Slackware 12 with updates. It has become increasingly cumbersome to compile new software given the number of dependencies that also have to be compiled, and have their own dependencies compiled, etc and so on.
Other than the fact that the adoption of new packages is somewhat glacial, and that there is no automatic dependency resolution, I really like Slackware. Its fast, relatively easy to configure, and easy to use. I'm conversant in commandline-ese.
I've been led to understand based on the Arch wiki that Arch is very similar to Slackware in its layout, but with bleeding edge packages and dependency resolution, so I would think it would be about perfect.
However, I also understand that the install is more difficult that Slackware. How much more so is my question. Is it impossibly confusing and unhelpful like Debian installation was, or just slightly more difficult than Slackware or FreeBSD (both of which have very smooth installation scripts)
Also, for packages that have to be compiled from source, are dependancies easy to satisfy from the arch repository, or do dependencies for new software have to be compiled with their dependencies.
I'd probably just be trashing everything but /home, and doing a clean reinstall.
Is Arch the right distro for me, or am I better off staying with Slackware? Like I said, I really like Slackware except for the package management issues.

You are right about that.
However, I also understand that the install is more difficult that Slackware. How much more so is my question. Is it impossibly confusing and unhelpful like Debian installation was, or just slightly more difficult than Slackware or FreeBSD (both of which have very smooth installation scripts)
They are quite similar, but Slackware provides more help when doing tasks like - how can I partition my harddisk and so on. But If you're comfortable with Slack's install procedure then installing Arch is much easier, just read the install guide.
I think Arch is good for you, because currently I have both - Slackware and Arch and both suit me fine for my needs.
Also remove all *. entries in your /home

Package manager - question?

Hello folks,
I wish to know why Package manager in openSolaris is so
slow application. I know that it is written in Python, but
I still do not understand why somebody did not offer some
patch for that application. I will help honestly in programming
if you need coders.
Uros

Please send your question to [email protected] That is the best place for discussion OpenSolaris packaging tools such as packagemanager. This forum is better for Solaris installation issues (from Solaris 10 and SXCE, for example).

Import Packages - A Question to All Java-Professionals

Question:
I installed the J2SE 1.3.1_02, J2EE 1.3.1_01 and Forte Java CE 3.0. Why I can't use the Packages included in the j2ee.jar located in the \bin directory?
I can't use the Packages like
import javax.jms.*;
import javax.sql.*;
Why? Please to all Java-Experts. Thank you very much

sorry this is kinda late, no I dont use forte, I use codewarrior , and I have not used the j2ee.jar but I have used the servlet.jar , activation.jar, and mail.jar . And I simply add a refrence to those files and Codewarrior sets the classpath for me.
