jaxws-tools wsgen UnsupportedClassVersionError

[Sam Merrell]

I've been searching all over for why I'm getting this error, but when I run
jaxws-tools wsgen, I am getting this:

Here are the contents of the HelloWorld.java file:

*// demonstrate web service with supplied wsdl and endpoint interface
package samples.example2;

import javax.jws.WebService;
@WebService(endpointInterface="samples.example2.HelloWorldSEI",
            wsdlLocation="WEB-INF/WSDL/HelloWorldService.wsdl")
public class HelloWorld {
    public String sayGreeting(String input){
            return("Example2 hello, " + input);
    }
}*

As you can tell I'm running IBM's JDK 5 and I'm using WebSphere Application
Server Community Edition. When I ran wsgen on this file using the standard
WebSphere Application Server's wsgen, I don't run into any problems. I only
get this problem with the community edition/Geronimo.

Any help or pointers in the right direction would be greatly appreciated.
