Swing Worker in JAVA 5
Hi ,
I want to add a progress bar in my applet while uploading the file on the server in JAVA 5.
I want to use Swing Worker for it . Do anybody have some code of implemetation of SwingWorker on JAVA 5 for progressbar?
Could you possibly download Java 6, get the source code for the SwingWorker class and use it? Regardless, most of what you use it for can be created with other constructs.

Please help me to implement the swing worker :( . i am using the abstractTableModal to populating the jtable it is working fine but swing worker is not there .
Scenerio is like this i have base frame on which i got 1 or more btton one of those button is Clients when i click on it a Jdialog box appears with the jtable . Pleae tell me how to implement the swing worker class between this. Pleaseeeeeeeeeeeeeeeeeeeeee :( I am help less now .Fahim i want to display some photograph in to a swing application after fetching these photo graph from the database table , i dont know what swing component will be better for it and i m designing this in netbeans , so please assist me with that , how to go now and please note that it is dynamic so component should be like that :(. i m trying to create a photo album where i upload the multiple photograph first then i would like to show them each photograph will a text box when some one write some text in that text box and press enter i would like to save that text with that photo graph , I AM DONE WITH THE PHOTO UPLOADING TASK BUT DONT KNOW HOW TO DO THE REST LIKE DISPLAYING THE PHOTOGRAPH WITH THAT TEXT BOX .

Mapping editor not working with Java 5 classes
I have a small protoype web service which I wrote using Tomcat/Axis/Spring/Hibernate and using EJB3 annotations for the mappings. I want to port the persistence layer to Toplink.
I installed Toplink 9.0.4.1 and added the toplink libraries to my project and implemented the DAO and the spring bean defs.
I opened the mapping editor and created a project. When I try to add classes to it for mapping I get an error that it can't find the classes (even though I selected them from the chooser). I figured it might be that they were compiled with Java 5, so I switched the JRE_HOME in setenv.cmd to my Java 5 JRE. Now I can import the classes and see the attributes but when I click on any of them in the Navigator panel, the editor panel remains blank. If I now try to save, I get:
java.lang.NullPointerException
at oracle.toplink.workbench.ui.tools.CheckListModel.getRowCount(CheckListModel.java:119)
at javax.swing.JTable.checkLeadAnchor(JTable.java:2949)
at javax.swing.JTable.tableChanged(JTable.java:2993)

at oracle.toplink.workbench.ui.tools.CheckList.initialize(CheckList.java:47)
at oracle.toplink.workbench.ui.tools.CheckList.<init>(CheckList.java:26)
It seems that the mapping workbench doesnt work with Java 5. What should I do?Ah, I see. I saw another post here stating that must use 10.1.3.

JTable - isEditing does not work in Java 1.4
I just upgraded jdk1.1.8 with swing 1.1.1 to Java1.4. The isEditing method doesn't work on Java1.4. When I edit a cell in the JTable and click a button , the value of the last edited cell is lost. I was able to catch the edited value by calling isEditing in jdk1.1.8 but Java 1.4 does not detect that the cell was edited. Is this a bug? Has anyone experience this problem? Is there a work around solution? Please help!!!
Hi,
Below is the code that I modified from a sample code in Java Tutorial. I added an OK button. The isEditing method does not trap the edit the first time but does on the second edit in JDK1.4. However, it works in JDK1.1.8. Am I doing something wrong or is this a bug? I desperately have to solve this problem to upgrade to JDK1.4. Thank-you for your help! I really appreciate it!

Creator Freeze Often -- SWING Worker thread also
I'm developping an app with creator. And I have many freezes in several minutes long as some people mentioned before.
I'm running win XP on an opeteron 244(1.8G) x2 , with 2G memory. I've updated creator to the latest updates, but it doesn't seem to be better.
The things I found is that when I edit Session Bean , Creator takes especially long time to come up.
At that time, SWING worker thread of Creator IDE also stopping, No update of display , I only look window frame.
You know the SWING has a Single thread model ,so if some logic uses SWING worker's thread long time, all displying process will be stopped.
Below is the stacktrace just after a few seconds when Creator freeze by editing Session Bean.
I use the stacktrace tool at http://tmitevski.users.mcs2.netarray.com/trace.do

Since swing is not thread safe the table is updated in a swing worker thread. This should ensure that all gui updates are scheduled in the main event dispatching thread. Following is that code :-
SwingWorker sw = new SwingWorker() {
public Object construct()
try{
_myTable.updateUI();
return null;
}catch(Exception e){
return null;
public void finished(){
sw.start();
Inspite of doing these i am getting these exceptions.try using javax.swing.SwingUtilities.invokeLater(Runnable doRun)

Swing worker question -- two lines performing a similar task concurrently
Hi,
I've been playing around with swingworker.
The code below has a window with two buttons and two text areas.
When you click a button, the text area will count out 10000 random numbers, and print "done." when it's finished.
Each of the buttons works when pressed separately (one is running while the other is idle) But I can't push one, then the other and have the tasks run independantly.
One stops and abruptly finishes while the other pauses.
Sorry to post a lot of code, I'm going through the tutorials, I've looked at the example from the tutorial pretty extensivley, but that is only running one task.
thanks.

BTW, I realize this code isn't as OOO as it could be (2 SwingWorker classes that do the same thing, 2 listeners that do the same thing) But I wanted to isoloate the problem first.
thanks.
Also, it's not impossible the program is working properly, it just finishes before the textArea can be updated.

Edited by: badperson on Feb 28, 2008 8:57 AMHi,
I reworked the code, and it now sort of works What I had wanted was to watch each window increment at the same rate, independant of each other. This will show a number in the window intemittenly, but not in a smooth continuous flow.
class BigJobWorker2 extends SwingWorker<Void, String>{
@Override
protected Void doInBackground(){
try{
for(int i=0; i<100000;i++){
int num2 = (int)(Math.random() * 100);
Integer integerNum2 = num2;
//tArea2.setText("iteration: " + i + " " + integerNum2.toString());
publish("iteration: " + i + " " + integerNum2.toString());
//ReallyBigJob rbj = new ReallyBigJob();
//tArea1.setText(rbj.doBigJob().toString());
publish("done.");
} catch (Exception e3){
e3.printStackTrace();
tArea2.setText("EXCEPTION:");
return null;
// override process method
@Override
protected void process(List<String> messages) {
Iterator i = messages.iterator();
while (i.hasNext()){
String message = (String)i.next();
tArea2.setText(message);
} // end BigJobWorker2thanks,

Applets not working with Java 1.7.0_51 in MII 14.0 SP4 Patch 5
Hi,
I'm currently evaluating the migration of our MII 12.0 developments to MII 14.
But I'm running in several issues just trying to use simple things like a SQL query template with an iGrid Display template in test mode.
Used versions are: MII 14.0 SP4 Patch 5 and on client side the latest Mozilla Firefox with Java 1.7.0_51
At first I always get a java security warning when the applet is being loaded about unsigned applications.
At second the applet itself is not running. It always shows "No data available" and the java console shows the following errors (iResult is the id of the applet):
iResult [ERROR] - Couldn't set query template: No Query Defined
iResult [ERROR] - Couldn't set display template: null
iResult [ERROR] - Couldn't set display template: null
Is this perhaps a general problem, that the MII applets are not working with Java 1.7.x versions?
If I call the same MII page from a client with Java 1.6.x it is working without errors.
Do you have some suggestions for me?
Regards Timoplease clear your JAVA Cache. that should solve the JRE issue. thanks

BAPI not working in Java Webdynpro
Hi,
My BAPI from SAP is working in Netweaver perfectly, but when I call the same with the equal parameters in Java webdynpro, no results.
I'm using following function: 'CVAPI_DOC_VIEW'.
Any idea why the BAPI is not working in Java Webdynpro?
Regards,
TimHi Tim,
AFAIK 'CVAPI_DOC_VIEW' will work only in standard SAP Dynpro. Inside Webdynpro it is forbidden to save files in the background and using GUI class with execute, so you cannot use that Standard FM.
Check this thread .
Thanks

How SDA and DDA works in Java Card?
Hi Friends,
I want to know how exactly SDA and DDA works in Java Card technology..
Yes, i know that SDA (Static Data Authentication) is valid for every transactions, but the key used is always same for every transaction made..
and DDA (Dynamic Data Authentication) uses dynamic key for every transactions, it means that one key is valid for one transaction..
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..
Please help me regarding this..
Thanks in advanceHi,
I want to know how exactly SDA and DDA works in Java Card technology..This is an EMV concept and as such is not implemented in Java Card as such. You would have to create an implementation to be able to use SDA and DDA.
But, i'm a little bit confused how this is implemented in Java Card..
Is it related with SCP01 and SCP02?..It is not implemented natively in Java Card and are not related to SCP. SDA and DDA are for the EMV card application (card application data updates) and SCP is for the card manager (card content updates). While they could be considered similar concepts, they are not related in a Java Card sense.

How to configure the work manager java code to eclipse?
Hello all,
I am working with the syclo work manager app. I have successfully installed all components required.
I imported the work manager mobile application and I want to import the standard work manager java code, what is the process to import java code into work space.
Guide me with some screen shots.
When I try to start the WM server it is giving me the following error:
How to resolve the error.
Please anyone provide me complete setup needed to run the work manager app smoothly.
Please guide me.
Thanks & Regards,
Swaroopa.Swaroopa,
That error is telling you the SAP JCo library cannot find one of the needed DLLs on the system. The sapjco.jar loads two additional DLL files (sapjcorfc.dll and librfc32.dll). Both should be installed by default into your ServerDev directory (assuming you are running Agentry 6.0.x).
I would guess it is having trouble loading the librfc32.dll based on the message but confirm both are in the correct location.
