I am using the jaxws-tools.bat to create the required artifacts for jax-ws webservice.
I ran the command jaxws-tools.bat wsgen on a command window and got the following error.

Exception in thread "main" java.lang.NoClassDefFoundError: org.apache.geronimo.c

I could find this class at <GERONIMO_HOME>\repository\org\apache\geronimo\framework\geronimo-common\2.1.

The previous version of geronimo on running the same command will give a help menu
