unable to start platform from within a jar...

WFG

Hello.
I wrote some classes using the birt enginge. Everything is fine, while I'm debugging in eclipse (I've added ALL jars from the engine folder as external jars).
Also I can run my app from the commandline via "java.exe myclass etc." (I've also added ALL jars from the engine folder to the CLASS_PATH-environment).
Now I'm trying to export may classes to a jar file (starting with "java.exe -jar myclasses.jar") and it doesn't start (I assume, the main class is found but the static main isn't invoked):

Exception in thread "main" java.lang.NoClassDefFoundError: org/eclipse/birt/core/framework/PlatformConfig
Caused by: java.lang.ClassNotFoundException: org.eclipse.birt.core.framework.PlatformConfig

anyone any idea????
many thanks and sorry, if this is not a birt-specific problem!
