Unable to set up apache cxf properly in eclipse

I use eclipse Helios Service Release 2 version for apache cxf. When I go to windo->preferences->Web services-> CXF 2.x preferences, and set up the cxf runtime, then the version and type doesn't get filled up automatically, which happens on any other system I have tried, What can 开发者_StackOverflowbe the problem? This is why, when I try to create a web service, it shows me "Java virtual machine error" - Could not find the main class, Program is exiting error.

Plz help me what to do to set up apache cxf properly in eclipse helios.

The problem was due to incompatibility of jaxb version present inside java and apache cxf. I update my java runtime to contain the latest version of jaxb (same in apache cxf and java runtime). It worked fine then.
