[Eclipseme-users] Null Pointer Exception when running "Create Package"

[Eugen S. <eug...@gm...>]

Hi,

I'm having trouble getting started with the eclipseme plugin. I've 
created a new J2ME project and i added a simple Test class. When i run 
"Create Package" on that project i get : "java.lang.NullPointerException 
encountered while running Preverification." with the full stack trace:
java.lang.NullPointerException

I'm using Eclipse 3.2.2 and eclipseme 1.7.7 on a windows xp machine. 
Could someone point me in the right direction?
Thanks,
Eugen
