Hi at all,
i'm new here, but i need a great help.
I have a client/server application based on ejb where the server classes runs on jre 1.4.1_05 and the client classes runs on 1.4.1_03.
The problem did appear since we're using windows xp with sp2 on client side.
The client classes runs throught java web start mechanism, the gui is swing.
The problem is totally random. The client application hangs with no reason, after user's click. I catched no precise condition that generates the lock state. There isn't no java exceptions. The "javaw.exe" process still remain in windows' task manager with cpu at 0%. The swing framework doesn't refresh the application screen when something override it.
No message (error or warning) appear in the event viewer except this one:
Event Type: Error
Source: Application Hang
Category: (101)
Event ID: 1002
User: N/D
this message is related to javaw.exe process
Only one time happened that windows killed javaw.exe process, after about 15-20 minutes from lock state.
When killed it generated the following message:
Event Type: Information
Source: DrWatson
Category: none
Event ID: 4097
User: N/D
Description: Application C:\Programs\Java\j2re1.4.1_03\bin\javaw.exe
generated application error.
Exception 80000003 generated on address 7C911230
(ntdll!DbgBreakPoint)
i'm desperated. I assume that it is a bug related to communication between jvm and winxp's socket layer.
If usefull i'll post hijackthis and process explorer nt report log.
thanks in advance to everyone can help me!
