[xmlvm-users] InvocationTargetException

[Wenjing Y. <wen...@gm...>]

Hello,

I tried to port a bundle of Java classes using XMLVM with "--target=posix".
The command I used is
      java -Xmx1G -jar <XMLVM_HOME>/dist/xmlvm.jar --in=src/java
--out=src/objc --target=posix --app-name=iPhoneApp

However I'v got an exception as follows:

Exception in thread "main" java.lang.reflect.InvocationTargetException

Could someone kindly advise me what's the problem here? Thank you.
