Java.lang.SecurityException: Prohibited package name: java.lang

I'm getting the following error when trying to build my very simple webservice project. I've given the build.xml, my java file and path values

The class file is getting generated, but service is not getting generated.

Please help… It's bugging for a looooong time..

Thanks! 🙂
