Problem in startnig the SWING application

I have made an application in java swing. the time to start the application is increasing day by day. Can anyone tell me the possible reasons for this. Earlier it used to start in about 1 minutes. But now it takes around 10 minutes to start the same application. just to start means to show up the GUI only.

1 minute is too long, 10 minutes is ridiculous.
There are products available that can help you determine where your application is spending time, and using resources (memory and CPU) called profilers. One I have trialed that would probably help is called OptimizeIt from Borland.
Here are a couple of questions that will help in determing what might be going on. The following information is first step in getting the factual information to try and help determine the reason for the long startup times. Still, without code, it can be quite difficult to determine where you may be slowing down:
1) Is it a large application (lots of function, or lots of Swing objects)?
2) What type of workstation are you running the application on?
2a) How much memory does the workstation have?
2b) What is the processor speed?
2c) What is the operating system?
2d) How much physical memory is available before you start your application?
2e) How much physical memory is available after you start your application?
3) Are you starting your application from the command line, or are you starting it through an IDE?
3a) What JVM parameters if any are you using to start your application?
4) Are you accessing files, or code across the network (shared drives on windows, or NFS on UNIX)?
5) Are you accessing any database within the application?
6) Are you showing a splash page while your application is loading?
7) Are you utilizing any configuration files for logs or .ini?
8) What version of Java are you running?
9) What vendor supplied the version of Java you are running?

Log of the swing application

When I run a swing application inside JDeveloper, if an exception is thrown, I see a log in Jdeveloper in 'Running' window.
Is there such log for the swing application deployed using webstart (somewhere on the client machine)?

Invoke an awt event from outside the swing application

Is it possible to invoke an awt event triggered from outside the swing app? I am trying to implement a use case where i have to open a new tab in an already running swing app when a user clicks on a browser link.

I have a desktop application that was invoked via webstart. The java webstart process started when the user clicked on a link that downloaded the swing application and now it runs in the clients JVM. Each browser click downloades and launches the application that performs a certain function. Now lets say, the user clicks on another link, then i don't want another java application to be launched. I want the same application that executes the function in lets say a new tab.
Its kind of like you click on a link that somebody sent you in an outlook email. When you click on it and if firefox is already running, the link opens up in a new tab on an already running firefox browser. If firefox was not running, it starts a new firefox process.
Hope this makes sense

Debug the swing application from eclipse

Hi
I had a swing application, to create a exe file i build the application using using build.xml. To run the application we need to open the exe file.
I want to debug this swing application from eclipse. Can anybody please tell me how to debug this application.
Note: I can able to debug simple swing application. But i can't able to debug this application.
Thanks
mindus

If it's an actual .exe--that is, if you've compiled it to a native Windows executable--then you can't debug it using a Java debugger (such as the one in Eclipse).
If, on the other hand, you just have a .jar file or a bunch of .class files, then you can debug this app the same way you debugged the other one.
If you don't provide more details about what you actually did and what exact problems you're having ("I can't do it" contains no useful information whatsoever), then it's impossible to provide any more detailed advice than this.

Problems related to the device application Blackberry

Hi All
I ma trying to create the sample application on Blackberry.
I followed the following steps:
1. On sybase 1.5.2 workspace i created a mobile application project.
2. Dragged customer dba and sales order dba on the diagram scree.
3. Created the relationships and deployed and generated the code.It generated successfully.
Nect i installed Blackberry JDE 1.3 under C drive that is outside the sybase installation root folder.
I opened the Blackberry JDE and created a blackberry project there.
I copied the src from the generated code folder to the scr folder under my BB app.
I added the two extenal jar files i.e sup-client-rima nd UltraliteJ but i get lots of compile errors when i included the mbo source folder under this folder.
When i tried including the jar files under the jre (the java jar files) the errors only increased.
Can some one please guide me here.I have been struggling since past many days on this.
Any help would be highly appreciated.
Thanks and Regards
Shweta

Hi
It is recommended to set the compiler settings to Java 1.3 or max 1.4, this can be found in the project properties->Java compiler.
Blackberry Application should be developed to run on BB devices that have JVM that is different from the one found on your PC.
So the reason you are having compile issues is because you are using API's not supported by the BB/SUP libraries.
Please take a look at BB and SUP supported API's before using any API.
Thanks

Also please help me with the password policy settings.

Check if when you close your app, the programm really exits.
When you close your main frame, the VM must be stopped (setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) or add System.exit(0) in the method windowClosing(...) of your window listener).
Maybe there are a lot of VM running at the same time.

Problem in building the enterprise application using Ant -Wrkshop

Hi All,
I have developed the enterprise application using workshop and tries to build the application using Ant script and getting the following error.
"An error occurred writing the controls client manifest."

Did you:
a). Ensure you're using the correct version of WLS (it appears to me you're using a standalone WLS)? - correct version is 10.3.3
b). Install the application development runtime 11.1.1.3?
c). Extend the domain with the JRF?

Hi,
This is a problem with your DNS settings (or lack of), not with Sun Java System Application Server/Access Manager.
You will need to setup DNS before installing.

Change The Swing Application Color

I Have an Application with several screens. There is an option for the user to change the background color for all screens.
But in my case the change will only occur when the application is executed again. (I store the color in a text file and reads it at run time - and change the backgounds of panels accordingly)
Cant I also make the change at that time. The thing is this change should occur for all screens of the application.
Please let me know if anybody have an idea on this ....
Thanks
Shirantha.

UIManager.put("Panel.background",color);
SwingUtilities.updateComponentTreeUI(yourFrame);

Thanks for the reply
I dont think so that any oter application is running
with that port.. Because i created a new server and
it takes the default port which is not in use.What if there is already a server using that port?
Try using netstat to check.

Java Swing application problem in Windows vista

When we execute the Swing application in windows vista environment.
The look and feel of the swing components are displayed improperly.

Problem in Opening HTML Page in Internet Explorer from my Swing Application

Hi,
I am opening a HTML file in Internet Explorer from my swing application.I am using the code given below
private final static String WIN_FLAG = "url.dll,FileProtocolHandler";
private final static String WIN_PATH = "rundll32";
String cmd = WIN_PATH + " " + WIN_FLAG + " " + url;
// url is HTML file Path
Process p = Runtime.getRuntime().exec( cmd );
Here there are two things i need to address ...
1)The HTML file is opening up,but it always opens behind the swing application,that makes me every time to maximize the HTML file after it being opened up.I want to open it in front of the Swing Application.I need to implement "Always On Top" functionality for the html page.
2)Whenever i trigger action to open different HTML page,it opens in new Internet Explorer window.
I need to open it in same IE window.
how to solve out these problems ??? any help would be greatly appreciated .Thanks in advance.
- Manikandan

any idea about this ????
