JAVA Webservice consumer java.lang.IncompatibleClassChangeError

Hi.I wrote a small test webservice in java

Ruinning on a notes server 8.5

The code below shows the service

public class HELLO{

// This is a template implementation class for your web service. It

// becomes extraneous if you import a WSDL document. Consumers of this

// web service can call any public method in the implementation class.

//

// To obtain a Session object use this code:

// Session s = WebServiceBase.getCurrentSession();

public String ReturnHello()

{

	return "HELLO";

}

if i create my consumer in Java and try to use „ReturnHello“

I receive:

Exception in thread “AgentThread: JavaAgent” java.lang.IncompatibleClassChangeError

at JavaAgent.NotesMain(Unknown Source)

at lotus.domino.AgentBase.runNotes(Unknown Source)

at lotus.domino.NotesThread.run(Unknown Source)

HELLO lService= new HELLOServiceLocator().getDomino();//lEndpoint);

System.out.println(lService.returnHello());

If i use the same WS using lotus script it works.

Can anybody help ?

Thanks

Subject: Addition

I found out this happens only after adding a second consumer. as long only one consumer exists everytiung works fine.
