PopUpAnchor listening for Scrolling

I have a PopUpAnchor, and when I scroll I need the position to update. So I'm calling the updatePopUpTransform() method.
When you use the scrollbar everything is good. However, when you scroll using the wheel, the updatePopUpTransform seems to be off by about 1 scroll. So if I need my PopUpAnchor to be right at the bottom of something on screen, now there is a gap between them. This doesn't happen when you scroll using the scrollbar though. Anyone have any ideas why these 2 are working differently?
Here's some of my code:
this.grid.addEventListener( ScrollEvent.SCROLL, myCallBack );
this.grid.addEventListener( MouseEvent.MOUSE_WHEEL, myCallBack);
And in my call back:
this.myPopup.updatePopUpTransform();
I've even tried having myCallBack just called from a single Event.SCROLL event, and that doesn't work either. Same results.
Thanks for the help!

Here is the client code... What I need is the server code... I want to save the file to hard disk, when a post is performed.And you want to use a servlet to do that? Then your google keywords are "file upload servlet". I recommend the links which recommend using Apache software in your servlet.

How do I listen for changes in a container's components?

I have a JScrollPane that contains a JTextPane. I want any Container that can possibly contain my JScrollPane to be able to listen for changes in the JTextPane's Document.
For example, at the moment I'm using a JTabbedPane to hold a number of my JScrollPanes and I want to alter the tab title when any associated JScrollPane-JTextPane-Document is updated.
Any suggestions on how best to handle this?

I would use a controller object that manages all your gui components (tabs, scrolls, documents, text panes). Your controller object can register as a listener to the appropriate component, and when it changes, update the title of a tab (or do whatever else) as appropriate.
Never put business logic like this stuff inside the actual gui components. Create, layout, etc. all the gui components (and related components like Document) from another controller like object instead. It makes handling the various listener stuff like this much easier. Read up on MVC (model view controller) stuff for more info.
As for the actual mechanics, you could get the document that is used in the JTextPane and register as a DocumentListener. As a document listener, you get notified of all changes that are made to that document.

How to listen to scrolling

Hi,
is it possible to listen to scrolling event on e.g. ListView? Something like:
myList.setOnScrolling(new EventHandler<Event>() {
            @Override
            public void handle(Event t) {
                System.out.println(t);
});I would like to be notified every time when the visible content of my list might be changed.

Run this code after you have placed your listview on a visible stage:
for (Node node: listview.lookupAll(".scroll-bar")) {
if (node instanceof ScrollBar) {
    final ScrollBar bar = (ScrollBar) node;
    bar.valueProperty().addListener(new ChangeListener<Number>() {
      @Override public void changed(ObservableValue<? extends Number> value, Number oldValue, Number newValue) {
        System.out.println(bar.getOrientation() + " " + newValue);
}You can find a complete example here: https://gist.github.com/1684622

Mouse motion listener for JTable with JScrollpane

Hi All,
I have added mouse motion listener for JTable which is added in JScrollPane. But if i move the mouse, over the vertical/horizontal scroll bars, mouse motion listener doesn't works.
So it it required to add mousemotionlistener for JTable, JScrollPane, JScrollBar and etc.
Thanks in advance.
Regards,
Tamizhan

I am having one popup window which shows address information. This window contains JTable with JScrollPane and JButton components to show the details. While showing this information window, if the mouse cursor is over popupwindow, it should show the window otherwise it should hide the window after 30 seconds.
To achieve this, i have added mouse listener to JPanel, JTable, JButton and JScrollPane. so if the cursor is in any one of the component, it will not hide the window.
but for this i need to add listener to all the components in the JPanel. For JScrollPane i have to add horizontal, vertical and all the top corner buttons of Scroll bar.
Is this the only way to do this?

ScrollBar event for scrolling or paging?

Does anyone know if there is an event that can be listened
for on a ScrollBar that is kicked off when the user content either
scrolls left or right by clicking on the arrows of the track? I
can't find an event like that in the documentation but it seems
like it should be there.
Thanks in advance,
Todd

The only thing I can figure is that the user getting the paginartor has accessibility turned on:
http://help.sap.com/saphelp_nw70ehp1/helpdata/en/19/e64941bfb4de2be10000000a1550b0/frameset.htm
That is the only option I know of that should override the system or application settings for scrolling. In particular accessibility can be turned on at the user profile level:
To do this, in transaction SU01 for your user name choose the tabstrip Parameters, insert the parameter ID ACCESSIBILITY_MODE with the value X, and save the entry.
Or within the portal:
To do this, in your user profile in the portal, under General Information select option Activate Accessibility (Screen Reader Required) and save your entries. This specification is evaluated by Web Dynpro ABAP.

Use 1 listener for multiple database in a server

hi guys,
just want to check whether this is the right way to configure my Listener.ORA . I am using 1 listener.ora to listen for incoming request connection from remote client. There are multiple databases installed in a server.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ora03)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = O11R2)
(ORACLE_HOME = /oracle/app/oracle/product/11.2.0/db_1)
(SID_NAME = O11R2)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = O10G)
(ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
(SID_NAME = O10G)
)sorry i am reading about it so did not install another database to test out. Just thinking in the line that it mention that the list of SID is refering to the multiple database that is installed in a server and i am using 1 listener.
Please further advice.

          (ORACLE_HOME = /oracle/app/oracle/product/10.2.0/db_1)
          (SID_NAME = BBBB)

How to configure multiple listeners to listen for the same instance.

Hello everyone,
I am running oracle database 11g and I want information regarding how to configure multiple listeners to listen for the same database instance. Actually I know how to configure more than one listener but the main thing that I am confused about is when we create listener.ora file, do we have to statically register the database instance with both the listeners or the instance will register itself with both the listeners.
According to my knowledge the instance will register with the listener specified by LOCAL_LISTENER parameter and we cannot have more than one value for this parameter.
Please only give detailed answers with example as I am tired of simple answers with details that I already know.

Hello,
Yes, it can make sense to have several listener for one Oracle instance. For instance you may have one listener for the applications another listener for DBA administration tasks as well as one listener dedicated to dataguard broker. It is not possible to have several listeners listening on the same IP and Port.
By default the database try to automatically register to a listener on port 1521. To instruct the instance to register to a specifc list of listeners you can add in the init.ora the local_listener parameter with an alias definition:
i.e
local_listener=MY_SET_OFF_LISTENERS
in your tnsname.ora add an entry called:
MY_SET_OFF_LISTENERS_LOCAL= (ADDRESS_LIST=
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1530))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1531))
(ADRESS=(PROTOCOL=TCP)(HOST=myhostname)(PORT=1532))
In this sample your instance will register to three listeners listening on respectively port 1530, 1531 and 1532
If you want your clients can be balanced over the 3 listeners

One Listener for multiple things?

Is is OK to use on listener for multiple events on the same object?
I have this for a FLV component and it seems to work. Is that legit?
var listenerObject:Object = new Object();
listenerObject.complete = function(eventObject:Object):Void {
trace("End of this video!!!!");
myVideo.addEventListener("complete", listenerObject);
listenerObject.stateChange = function(eventObject:Object):Void {
trace("stateChange just occurd!!!");
myVideo.addEventListener("stateChange", listenerObject);
Thanks a lot for any info!!!

Yup no problem. However I would group my listener object properties close together.
listenerObject.complete=function(e:Event){
// blah blah
listenObject.progress=function(e:Event){
// blah blah blah
And so on. If they end up separated you most likely will forget over the course of time and then when you come back you might delete the object after you use it for one event and forget that it has others.

Huge performance differences between a map listener for a key and filter

Hi all,
I wanted to test different kind of map listener available in Coherence 3.3.1 as I would like to use it as an event bus. The result was that I found huge performance differences between them. In my use case, I have data which are time stamped so the full key of the data is the key which identifies its type and the time stamp. Unfortunately, when I had my map listener to the cache, I only know the type id but not the time stamp, thus I cannot add a listener for a key but for a filter which will test the value of the type id. When I launch my test, I got terrible performance results then I tried a listener for a key which gave me much better results but in my case I cannot use it.
Here are my results with a Dual Core of 2.13 GHz
1) Map Listener for a Filter
a) No Index
Create (data always added, the key is composed by the type id and the time stamp)
Cache.put
Test 1: Total 42094 millis, Avg 1052, Total Tries 40, Cache Size 80000
Cache.putAll
Test 2: Total 43860 millis, Avg 1096, Total Tries 40, Cache Size 80000
Update (data added then updated, the key is only composed by the type id)

Hi Robert,
Indeed, only the Filter.evaluate(Object obj)
method is invoked, but the object passed to it is a
MapEvent.<< In fact, I do not need to implement EntryFilter to
get a MapEvent, I could get the same result (in my
last message) by writting
cache.addMapListener(listener, filter,
true)instead of
cache.addMapListener(listener, new
MapEventFilter(filter) filter, true)
I believe, when the MapEventFilter delegates to your filter it always passes a value object to your filter (old or new), meaning a value will be deserialized.
If you instead used your own filter, you could avoid deserializing the value which usually is much larger, and go to only the key object. This would of course only be noticeable if you indeed used a much heavier cached value class.
The hashCode() and equals() does not matter on
the filter class<< I'm not so sure since I noticed that these methods
were implemented in the EqualsFilter class, that they
are called at runtime and that the performance
results are better when you add them
That interests me... In what circumstances did you see them invoked? On the storage node before sending an event, or upon registering a filtered listener?
If the second, then I guess the listeners are stored in a hash-based map of collections keyed by a filter, and indeed that might be relevant as in that case it will cause less passes on the filter for multiple listeners with an equalling filter.
DataOutput.writeInt(int) writes 4 bytes.
ExternalizableHelper.writeInt(DataOutput, int) writes
1-5 bytes (or 1-6?), with numbers with small absolute
values consuming less bytes.Similar differences exist
for the long type as well, but your stamp attribute
probably will be a large number...<< I tried it but in my use case, I got the same
results. I guess that it must be interesting, if I
serialiaze/deserialiaze many more objects.
Also, if Coherence serializes an
ExternalizableLite object, it writes out its
class-name (except if it is a Coherence XmlBean). If
you define your key as an XmlBean, and add your class
into the classname cache configuration in
ExternalizableHelper.xml, then instead of the
classname, only an int will be written. This way you
can spare a large percentage of bandwidth consumed by
transferring your key instance as it has only a small
number of attributes. For the value object, it might
or might not be so relevant, considering that it will
probably contain many more attributes. However, in
case of a lite event, the value is not transferred at
all.<< I tried it too and in my use case, I noticed that
we get objects nearly twice lighter than an
ExternalizableLite object but it's slower to get
them. But it is very intersting to keep in mind, if
we would like to reduce the network traffic.
Yes, these are minor differences at the moment.
As for the performance of XMLBean, it is a hack, but you might try overriding the readExternal/writeExternal method with your own usual ExternalizableLite implementation stuff. That way you get the advantages of the xmlbean classname cache, and avoid its reflection-based operation, at the cost of having to extend XMLBean.
Also, sooner or later the TCMP protocol and the distributed cache storages will also support using PortableObject as a transmission format, which enables using your own classname resolution and allow you to omit the classname from your objects. Unfortunately, I don't know when it will be implemented.
>
But finally, I guess that I found the best solution
for my specific use case which is to use a map
listener for a key which has no time stamp, but since
the time stamp is never null, I had just to check
properly the time stamp in the equals method.
I would still recommend to use a separate key class, use a custom filter which accesses only the key and not the value, and if possible register a lite listener instead of a heavy one. Try it with a much heavier cached value class where the differences are more pronounced.
Best regards,
Robert

Thank youbfor optimizing the touch input for scrolling on my HP Slate 500, why wont the others do the horizontal scrolling feature enables?

After testing all other available browsers the past month I have arrived at the conclusion that the Firefox browser is the only one that enables touch input for scrolling. Trying to navigate pages without this function using IE, Opera, Safari & Chrome is just tedious. I'm using the Slate as it was intended, business functions especially day to day charting for my patients in an online system.
The larger tabs for opening new searches & sites. If Microsoft plans on making W8 truly touch enabled they need to take note of what FF has done here. The touch input is limited on W7 but you've succeeded where others have failed.
3 cheers for FF! I couldn't do my job and document patient progress w/o your intuitive design. Brendan S. - Latham, NY
I guess the question is why are the others not developing these key features for Windows based slates...are they ignorant or is FF that much further ahead.

How to stop and start MDBs to listen for JMS messages

Hello! This might be more of an architecture question rather than a technical questing, but I post it here, in the lack of a better place...
For several years I have been using Webster and Webster MQ to send messages back and forth to clients. The architecture for the middleware platform has been designed around the functionality of ListenerPorts. Listenerports is a Webster functionality that let you "stop" and start to listen to JMS messages for a given MDB either by admin console, or by JMX.
The arhitecture we used was something like this :
1.Client sends a persistent message to a queue. (order)
2. An MDB pics up the order message, calls a SessionBean that "fronts" the IIOP back end system.
This is quite "out of the box" architecture, but we used the Listenerports to solve a stability problem for our back end system.
The backEnd system was quite unstable, so the EJB threw an exception (typically because of timeout or connection refused) back to the MDB.
The Listenerport was "defined" to handle 3 errors before stopping, so the MDB resent the message twice before the listenerport automatically stopped. The nice thing about this feature was that the client could continue to send orders, and was not bothered when the back end system was down.
When the backEnd system was up and running, we could start the listenerport and it was all back to normal state. We even had a start script that checked the state of the listenerport every 30 minute, and started it automatically if it was stopped, making the admin task of starting the MDB unnecessary..
Now.. Why am I telling this story..
I would like to know how this could be done using "clean" J2EE technologies..That is..Not using any technology that is not portable..
I`m playing with glassfish at home, and it struck me that there is nothing in the J2EE spec that defines the functionality described above ? Am i missing something ?
I Do not want to stop My application because the back end system is down? That is the only way (i know of) that i can "stop" to listen for messages..
I can put all the messages on an error queue when the backbend system is down, but that would lead to more code just to handle the error messages. Maybe the easiest way to solve this is to "move" (programmatically) all messages from the error queue over to the "standard" queue every XX minute, but somehow that sounds "wrong"
Can anyone give me some advice to how this problem situation should be solved ? I`m interested in the solution both from an architectural perspective and from a more technical perspective..
Best regards

Breakpoints, whether normal or conditional, are just meant for debugging of your code. I had the sense from your question that the pausing you want to do is a part of normal operation of your code. I would NOT recommend using a breakpoint for that situation. It would bring up the block diagram showing the breakpoint when it occurs. A user besides the programmer would not know what to do in that case.
Yes, both the inner and outer loops would have shift registers.
Putting a case structure with a small while loop inside the "Pausing Case" is doable. It just depends on what you are doing or waiting for while the program operation is "paused".

On starting WebLogic getting Error : Listening for transport dt_socket at address: 8453 Exception in thread "main" java.lang.NoClassDefFoundError: vXmx512m

Hi,
system i am using for Oracle SOA is :
Windows 64 Bit
i5 Processor
6 GB RAM
29 GB on C Drive is already free after installation of all SOA related products.
I have installed wlserver_10.3 for SOA 11g Development purpose and followed exact installation sequence and procedure as mention in oracle documentation
i created domain also and every thing look correct but after installation procedure there are "Additional actions required just after every thing installed" :
setting memory limit
starting weblogic server (Admin Server)
starting weblogic managed server
and so on
now Problem is when i execute C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin startWebLogic.cmd
as mention in oracle documentation i am getting following error message : (i have only included last error lines instead of complete console log)
oConsole= -Dweblogic.ext.dirs=C:\Oracle\MIDDLE~1\patch_wls1036\profiles\default\

Could not find the main class: ++Xmx512m. Program will exit.
Now to resolve this what i already tried are :
I change JAVA_HOME and PATH to jdk6 which came with web logic installer
Location is at :
JAVA_HOME : C:\Oracle\Middleware\jdk160_29
PATH : C:\Oracle\Middleware\jdk160_29\bin
The above dose not include any space between path
I ran the startWebLogic.cmd and got same error
After that I also added
CLASSPATH : C:\Oracle\Middleware\jdk160_29\lib\tool.jar;C:\Oracle\Middleware\wlserver_10.3\server\lib\weblogic.jar;C:\Oracle\Middleware\jdk160_29\bin
WL_HOME: C:\Oracle\Middleware\wlserver_10.3
I ran the startWebLogic.cmd and got same error
I also used earlier path which I used with eclipse when I was working on other java development.
JAVA_HOME : C:\Program Files\Java\jdk1.7.0_21
PATH : C:\Program Files\Java\jdk1.7.0_21\bin
I ran the startWebLogic.cmd and got same error
Then I also gave PATH: C:\Oracle\Middleware\wlserver_10.3\server\lib      (including the existing one using ; )
I ran the startWebLogic.cmd and got same error
Now may be there is a file called setSOADomainEnv.cmd in
< C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\ setSOADomainEnv.cmd>
That include some values for memory set :
set JAVA_OPTIONS=%JAVA_OPTIONS%
set DEFAULT_MEM_ARGS=-Xms512m –Xmx512m
set PORT_MEM_ARGS=-Xms512m –Xmx768m
if "%JAVA_VENDOR%" == "Oracle" goto OracleJVM
set DEFAULT_MEM_ARGS=%DEFAULT_MEM_ARGS% -XX:PermSize=128m -XX:MaxPermSize=768m
set PORT_MEM_ARGS=%PORT_MEM_ARGS% -XX:PermSize=256m -XX:MaxPermSize=768m
now as I change the red highlighted value to 512 value because I have less memory resource and I checked in installation documentation to change the above red highlighted value to 512 original is 1024 which is too high and it was crating problem and showing memory space problem so I change it to 512 and now I am not getting that memory space problem error but may be the above error is related with change value in setSOADomainEnv.cmd file or not
Following are my domain, weblogic and soa home directory path and all these path are exactly what it suppose to be according to Oracle Installation Documentation:
WebLogic :
C:\Oracle\Middleware\wlserver_10.3
C:\Oracle\Middleware\coherence_3.7
C:\Oracle\Middleware\oepe_11.1.1.8.0
SOA Oracle Home Directory :
C:\Oracle\Middleware\Oracle_SOA1
OSB Home Location :
C:\Oracle\Middleware\Oracle_OSB1
Domain name : soa_div_domain
Domain Location :       C:\Oracle\Middleware\user_projects\domains
Application Location : C:\Oracle\Middleware\user_projects\applications
Domain Location:        C:\Oracle\Middleware\user_projects\domains\soa_div_domain
form here i am trying to start weblogic : C:\Oracle\Middleware\user_projects\domains\soa_div_domain\bin\startWebLogic.cmd
Please tell me any body want more details.
Thanks.

I think you are missing a character '-'
USER_MEM_ARGS="Xms512m -Xmx512m -XX:MaxPermSize=128m"Add this character like follows
"-Xms512m -Xmx512m -XX:MaxPermSize=128m"

What is the keyboard shortcut for scrolling page down? In Pages, Safari, etc... Just a single page/ screen view, not all the way to the bottom. Thank you.

Trying to navigate the screen without my mousepad. I have carpal tunnel and early stage arthritis and cannot repeatedly make the appropriate motions to scroll with two fingers. Is there a keyboard shortcut for scrolling up and down line by line or page by page?
Thank you.

Yeah. sorry. those are not correct. ctrl N + P are for home and end line shortcuts. Ctrl V does go down one line. But CTRL arrow up or down do not work in Safari. But thank you very much for the attention and the time...
Note from my first post above -- I did not say to use CTRL arrow in Safari:
For Safari:
Scroll down a line: down arrow
Scroll down a screen: option down arrow
Note from my second post above and from the first link I gave that Control N, P, and V worked for me in Pages as described in the link and in my post:
The link to shortcuts that I gave abaove includes Control N, P, and V for move down a line, up a line and down a page and those seem to work in Pages.

Listening for the end of a movie

Hi, I have some code that loads a movieclip into an empty
clip
var container:MovieClip =
this.createEmptyMovieClip("container", this.getNextHighestDepth());
container.attachMovie("twdc_mc", "twdc_mc", 1, {_x:300,
_y:275});
then i want to wait until the end of the movieclip, unload it
and load another in its place - all without leaving frame one of my
main timeline...so my initial thought was to add this:
function getframes(numFrames,totalFrames) {
if (numFrames == totalFrames){
trace("removed") //changed the return variable to this for
testing
container.twdc_mc.onEnterFrame =
getframes(container.twdc_mc._currentframe,container.twdc_mc._totalframes);
(the use of a function because i want to re-use it)
the problem is that the if statement is parsed and evaluated
to false immediately, then it moves on to the next statement
without looking back despite the existance of the onEnterFrame
function
So my question is how can I listen for this event without the
need to add unLoad or removeMovieClip to the end of the offending
mc?
Thankyou in advance for any replies, I'm trying hard to get
to grips with "as" but Im a php boy at heart and really struggling!
Sam

Hi Sam,
in AS, you can't pass parameters to an event or callback
function like onEnterFrame this way. You can either pass a function
reference (without brackets, otherwise the function would execute
immediately and the event is undefined after that):
container.twdc_mc.onEnterFrame = getframes;
or define a function 'on the fly':
container.twdc_mc.onEnterFrame = function(){
Since you want to use the first way, getframes() can't have
any parameters, but instead it can use the scope of the event it is
bound to through the 'this' keyword:
function getframes() {
// trace(this._totalframes);
if (this._currentframe == this._totalframes){
trace("removed")
Now 'this' depends on the scope in which getframes() is
called, so you can use it with the onEnterFrame event of the loaded
clip:
container.twdc_mc.onEnterFrame = getframes;
and it will compare twdc_mc's position to it's end. Bound to
another MC it would take that MC's values.
cheers,

Issue with setting an Action Listener for a Command Button

Hi all,
I'm trying to set an action listener for a CoreCommanButton in a backing bean. Here's my code:
     CoreCommandButton editBtn = new CoreCommandButton();
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",null);
          editBtn.setActionListener(mb);
//Action listener method
     public void doButtonAct(ActionEvent actionEvent)
I keep getting a javax.faces.el.MethodNotFoundException error. However when I remove the ActionEvent parameter in doButtonAct(), I get a wrong number of arguments error.
So i'm guessing there is something wrong with the parameters i accept in my action listener method. what can be causing this issue?
Cheers.

I figured this out.
Since doButtonAct() requires an ActionEvent object as a parameter, i needed to define the parameter type when I create the method binding.
Solution:
     Class argsString[] = new Class[] { ActionEvent.class };
          MethodBinding mb = FacesContext.getCurrentInstance().getApplication().createMethodBinding("#{backBean.doButtonAct}",argsString);
