Cannot create WS artifacts for POJO when in default package

You cannot create a webservice from a simple pojo which is in the default package.

I note there is a warning on the Web Service Dialog box -

! The service implementation selected does not follow Java naming conventions.

But it still allows you to progress. until you get the following -

log4j:WARN No appenders could be found for logger (org.jboss.wsf.framework.DefaultSPIProvider).
log4j:WARN Please initialize the log4j system properly.
Error: Could not generate. (use --show-traces to see full traces)
Error: Cannot obtain @WebService annotation from: myPojo

I can't see anything in the docs[1] to prohibit this.
