Web Services in Java using JAX WS

[Argon]

I've been toiling over this problem for 2 days now and still can't find the solution. Narrowed it down to a NoClassDefFoundError that is being sent to the logfile. Basically the JAX WS plugin is supposed to generate a WSDL file automatically when the program builds, but for some reason it's not doing so.

Error looks like this:

Code (interface class) looks like this:

import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.xml.ws.RequestWrapper;
import javax.xml.ws.ResponseWrapper;
import javax.jws.WebMethod;

@SOAPBinding(use=SOAPBinding.Use.LITERAL, style=SOAPBinding.Style.DOCUMENT)
@WebService(name="Greeter", targetNamespace="http://src/")
public interface Greeter
{
@WebMethod(operationName="sayHi", exclude=false)
@ResponseWrapper(className="src.SayHiResponse", localName="sayHiResponse", targetNamespace="http://src/")
@RequestWrapper(className="src.SayHi", localName="sayHi", targetNamespace="http://src/")
public String sayHi(String value);
}

Please help!!!
