For me,

Last time, when I was using EJB, I used http://www.junitee.org/ and it works great.


However, other may have other suggestions so you may be waiting for alternative solution

I need to test the CMP entity bean for inserting a record into the database

The CMP entity bean contains the following classes


The IDE create the Junit template like below:

package com.fujitsu.au;

import junit.framework.TestCase;

public class TestInsert extends TestCase {

      public TestInsert(String arg0) {


Any idea what else i need to add to the above TestInsert

The URL that I gave you is the sample to test on EJB.

Basically, you need to create one more web application to test the EJB. If you need more detailed of the steps, look at

It may be a bit complicated to set up but should be doable.

Can I test without creating the web page?

I remember when I was at Sun's J2EE course, they can test the EJB function before creating web page.

like below: ( From sun's j2ee course I attented). But when i do the same thing, it does not work from within the IDE

Test for Searching
package bank;

import javax.naming.*;
import javax.rmi.*;
import java.util.*;

public class CustomerTest {

  public static void main(String [] args) {
    try {
      Hashtable props = new Hashtable();
      props.put ("java.naming.factory.initial",
      props.put ("java.naming.provider.url",
      Context c = new InitialContext(props);

      Object obj = c.lookup("ejb/Customer");
      CustomerHome customerHome =
        (CustomerHome) PortableRemoteObject.narrow(obj, CustomerHome.class);

      Customer cust = customerHome.findByPrimaryKey(new Integer(1));
      System.out.println("firstname: " + cust.getFirstname());
      System.out.println("lastname: " + cust.getLastname());
      System.out.println("address: " + cust.getAddress());
      System.out.println("phone: " + cust.getPhone());
      System.out.println("balance: " + cust.getBalance());
      System.out.println("new balance: " + cust.getBalance());

      Collection customers = customerHome.findByBalance(50);
      Iterator it = customers.iterator();
      while(it.hasNext()) {
        cust = (Customer) it.next();
    } catch (Exception e) {

Grr...never used that...can't really help on this.

>>"like below: ( From sun's j2ee course I attented). But when i do the same thing, it does not work from within the IDE"
It is not JUnit but it is a simple java class that called EJB and do the necessary invokation.

Give me a sec....

I can't really help you much on this as I have limited knowledge of your IDE.

>>"I remember when I was at Sun's J2EE course, they can test the EJB function before creating web page."
This could be a good starting point to you albeit it is not JUnit. Try to run it as a simple Java application. The error may come out that you cannot find the EJB properly.

The good sample of JUnit is

But that is for Eclipse :(

When i compile the below, it says "junit.framework never use" WHY.

import junit.framework.TestCase;
import java.rmi.RemoteException;
import java.util.Date;

import javax.naming.Context;
import javax.naming.InitialContext;
import javax.rmi.PortableRemoteObject;

import com.fujitsu.au.servicerequest.util.ServiceRequestException;
import com.fujitsu.au.servicerequest.ServiceRequestProcessorHome;
import com.fujitsu.au.servicerequest.ServiceRequestProcessor;

import junit.framework.TestCase;

public class TestInsert extends TestCase {

        protected ServiceRequestProcessor sr;

          public TestInsert(String name) { super(name); }

            protected void setUp() throws Exception {
                  Context jndiContext = new InitialContext();
                  Object einRef = jndiContext.lookup("java:comp/env/ejb/ServiceRequestProcessorBean");
                  ServiceRequestProcessorHome home =
                  this.sr = home.create();

            protected void tearDown() throws Exception      {
                  this.sr = null;

        public void testInsertRec() throws RemoteException, ServiceRequestException {            
              Date todayDate = new Date();
                  ServiceRequestModel srRec = this.sr.saveServiceRequest("DOR-20061123-01",
