hi,

I implemented the webservice then i want to test the webservice.

then client can access this webservice using servlets.

I got the error in testing the webservice .soap request is send but not the response.(i.e response return o)

First i implement the Entity Class(Customer1) and the instance variables id,firstname,lastname.

webservice code is:

package com.iton;

import java.util.logging.Level;

import java.util.logging.Logger;

import javax.annotation.Resource;

import javax.jws.WebService;

import javax.jws.WebMethod;

import javax.jws.WebParam;

import javax.naming.Context;

import javax.naming.InitialContext;

import javax.naming.NamingException;

import javax.persistence.EntityManager;

import javax.persistence.PersistenceContext;

import javax.persistence.Query;

import javax.transaction.HeuristicMixedException;

import javax.transaction.HeuristicRollbackException;

import javax.transaction.NotSupportedException;

import javax.transaction.RollbackException;

import javax.transaction.SystemException;

import javax.transaction.UserTransaction;

@WebService()

@PersistenceContext(name = "persistence/LogicalName", unitName = "Update5PU")

public class UpdateWS5 {

@Resource

private UserTransaction utx;

EntityManager em;

private int i;

public UpdateWS5() {

try {

Context ctx = (Context) new InitialContext().lookup("java:comp/env");

em = (EntityManager) ctx.lookup("persistence/LogicalName");

} catch (NamingException ex) {

ex.printStackTrace();

}

@WebMethod

public int Update(@WebParam(name = "id") int id, @WebParam(name = "firstname") String firstname, @WebParam(name = "lastname") String lastname) {

Query query=em.createQuery("UPDATE Customer1 c SET c.firstname = :firstname , c.lastname = :lastname WHERE c.id = :id");

query.setParameter("firstname","hai");

query.setParameter("lastname","hello");

query.setParameter("id",2);

try {

utx.begin();

} catch (SystemException ex) {

ex.printStackTrace();

} catch (NotSupportedException ex) {

ex.printStackTrace();

}

try{

i=query.executeUpdate();

em.persist(query);

System.out.println("the return value of executeupdate method is"+i);

} catch(Exception e) {

e.printStackTrace();

try {

utx.rollback();

} catch (IllegalStateException ex) {

ex.printStackTrace();

} catch (SecurityException ex) {

ex.printStackTrace();

} catch (SystemException ex) {

ex.printStackTrace();

}

try {

utx.commit();

} catch (SecurityException ex) {

ex.printStackTrace();

} catch (IllegalStateException ex) {

ex.printStackTrace();

} catch (RollbackException ex) {

ex.printStackTrace();

} catch (SystemException ex) {

ex.printStackTrace();

} catch (HeuristicRollbackException ex) {

ex.printStackTrace();

} catch (HeuristicMixedException ex) {

ex.printStackTrace();

}

return i;

}

I got the error like:
