[jboss-user] [JBossWS] - Re: ClassCastException in HandlerResolverImpl.addHandler

[rishabh2u]

I am getting this problem as well when implementing jaxws on jboss421 and 423. 
As per the java spec the handler class should either implement the javax.xml.ws.handler.LogicalHandler OR javax.xml.ws.handler.SOAPHandler.
 
I have a handler class that does this.
  | 
  | package handlertest.server;
  | 
  | import java.util.Set;
  | 
  | import javax.xml.namespace.QName;
  | import javax.xml.ws.handler.MessageContext;
  | import javax.xml.ws.handler.soap.SOAPHandler;
  | import javax.xml.ws.handler.soap.SOAPMessageContext;
  | 
  | public class ServerSOAPHandler implements SOAPHandler<SOAPMessageContext> {
  | 	private final String HANDLERNAME = "ServerSOAPHandler";
  | 
  | 	public ServerSOAPHandler() {
  | 		super();
  | 		System.out.println(HANDLERNAME + " ServerSOAPHandler():");
  | 	}
  | 
  | 	public Set<QName> getHeaders() {
  | 		System.out.println(HANDLERNAME + " getHeaders():");
  | 		return null;
  | 	}
  | 
  | 	public boolean handleFault(SOAPMessageContext arg0) {
  | 		System.out.println(HANDLERNAME + " handleFault():");
  | 		return false;
  | 	}
  | 
  | 	public boolean handleMessage(SOAPMessageContext arg0) {
  | 		System.out.println(HANDLERNAME + " handleMessage():");
  | 		return false;
  | 	}
  | 
  | 	public void close(MessageContext arg0) {
  | 		System.out.println(HANDLERNAME + " close():");
  | 	}
  | }
  | 

I get the same exception when this handler is loaded. This is the stacktrace.

The proposed solution of using Generic handler from Jboss works but this is not a proper solution. To be able to work with JAXws 2 spec I need to implement the javax.xml.ws.handler.LogicalHandler. Can you please suggest what can i do here ???

Also below are some links to jaxws 2 tutorials
