Java EE (Java Enterprise Edition) General Discussion

Following the instruction in Chapter 12: Building Web Services With JAX-RPC, I wrote a service similar to helloservice. But I got the following error while trying to deploy the service. Can anyone tell me if it is the problem of the configration file (e.g. config-interface.xml, jaxrtp-ri.xml) or the problem of my source code?

Thanks in advance for you time and your help.
