I am using jwap in the arm platform(S3C2410), my program works well in both Windows and Linux(FC6 JDK1.4),and I used
Blackdown JVM 1.3 as the JVM in the arm board,
I met this problem when the jwap thread started
Is X11 environment a must in the arm board to run program using jwap.jar?
Anyone has encountered similar problem? or know the answer?
java.lang.InternalError: Can't connect to X11 window server using ':0.0' as the value of the DISPLAY variable.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I think this is not related to jwap, but to your application which needs some GUI. You should set the DISPLAY Variable ("DISPLAY=localhost:0.0" or similar, just google for it).´
