[jboss-user] [JBossWS] - javax.xml.rpc.JAXRPCException: Cannot create or send respons

[rashmi_yes]

Hi,
i am new to webservice. I tried to create a web service with a single method & called from client. It works fine. But when I add one more webservice method & called the first method from the client. The call goes to server works till the return but while returning, it throws the below error. Please help me on this.

WS Code is :

@Stateless()
@WebService()
public class REFactory {
    /**
     * Web service operation
     */
    @WebMethod
    public String display(@WebParam(name = "s") String s) {
        // TODO implement operation 
        System.out.println("In method 1 :::: "+s);
        return "From method 1";
    }

    /**
     * Web service operation
     */
    @WebMethod
    public String createSession(@WebParam(name = "vo") Object vo) {
        System.out.println("In method 2 ...........");
        return "From method 2";
    }   
}

Error is :
