JDE dosen't start any more

Hi folks,


I developed my applikation on JDE 6.4.1.

A few days ago I installed all the other JDE for testing purpose.

Now I can't start any JDE. I deinstalled all JDEs and installed the JDE 4.6.1 again.

But it starts just one time after reinstallation. Once closed the JDE dosen't start anymore.

Same happens with all the other JDEs.

Re: JDE doesn't start any more

Has anything else changed on your PC?  Were other versions of Java installed?  What version of JDK are you using?  What version of Windows?  Do you see any error or exception during startup?


If not, try running the following command from a command prompt within the bin directory in your BlackBerry JDE installation directory.



javaw -Xmx512M -DRIM_RUNTIME=..\lib -DRIM_BIN=..\bin -jar IDE.jar


This is the command used to start the BlackBerry JDE.  Running it from a command prompt should allow you to see any errors or exceptions are thrown during startup.

Re: JDE dosen't start any more

if you had installed any simulator after installing the JDE then might be the problem.


i have this ongoing problem where i install any new sim the JDE wont start.

To fix the problem i just uninstall the sim.
