Hi All,

I have tried all available options in Forums, but still i am facing the same problem while Logging to my application. When i Debug the Application i found that the problem is with the Class Initialization(i.e crating a Class Instance) at that point the Debug Stop and in Simulator it remains the Login Screen itslef.
but if run the Application in Run mode it throws and exception
"JVM Error 104 Uncaught: NoClassDefFoundError"

And let you know that the same code working fine in J2ME default Simulator.

I have been struck here for last 3 days, Please Help me out in solving this Issue.

Thank You in Advance,
Regards
Vinay

This is probably a JDE level/OS level mismatch issue.

For example, if you compile on 5.0, but run the code on 4.5, you will get something like this.

The JDE level must be less than or equal to the target OS.

I'm also tearing my hair out trying to find the problem. I'm using the standard Blackberry JRE 5.0.0 and using default java compliance compiler settings. It happens when I add the following class:

Also, I have some previous blackberry projects which keep installing on the emulator even though they've been deleted from the workspace and reappear everytime I launch. How do I delete them permanently?!

[Dougsg38p]

What class is it coimplaining about? Where is the stack trace?

Please do some basic problem determination here...
