Help Needed On IBM VAJ 3.5 WTE

[vaibhav waghmare]

hi there,
I'm using IBM VAJ 3.5 for EJB developement. I'm able to test my beans with Websphere Test Environment, but when I run my own Client program to test the bean, I get following error message :
NoClassDefFoundError javax.naming.InitialContext
I get this error message when I try get InitialContext with the new Properties.
My Client code goes as follows :
--------------------------------

try{
   Properties p=new Properties();
   p.put(Context.INITIAL_CONTEXT_FACTORY,"com.ibm.ejs.ns.jndi.CNInitialContextFactory");
   p.put(Context.PROVIDER_URL,"iiop://localhost:900");
   InitialContext ic=new InitialContext(p);
   Object homobj=ic.lookup("vaib/demo/ejb/Vtable");
   VtableHome home=(VtableHome) javax.rmi.PortableRemoteObject.narrow(homobj,vaib.demo.ejb.VtableHome.class);
   Vtable quote = home.findByPrimaryKey(new VtableKey(new BigDecimal("1")));
   System.out.println("Emp Name : "+quote.getName());
   System.out.println("Emp Dept : "+quote.getDepartment());
}catch(Exception ex){
  String s=ex.toString();
}

please do the needful,
-VaibhaV.

Add the ujc.jar file to your classpath- this file is for the Naming package, ull find this i websphere application server directory/lib , then add it by going to window-options-resources-edit-add jar/zip, after this right click on the application u made and go to run, there check classpath- compute now.
This should work around the problem of not finding InitialContext.

hi daman,
I'v tried another client program using AccessBean, but this time it gives some other error.
My Client code is :
-------------------
try
{
System.out.println("Begin Test");
VtableAccessBean a = new VtableAccessBean();
System.out.println("AccessBean Instance Created ...");
a.setInitKey_id(new BigDecimal("1"));
System.out.println("Init Key set to 1 ...");
System.out.println("Name of Employee #1 : " + a.getName());
System.out.println("Department of Employee #1 : " + a.getDepartment());
}
catch (Exception e)
{
e.printStackTrace();
}
The exception Stack trace is :

Hi daman,
unfortunately i haven't installed WAS on my m/c. and because of the same i was unable to locate the file ujc.jar. Can you tell me from where else i can get this file ?
thx in advance,
-VaibhaV.

vaibhav waghmare,
I was thinking of mailing you the jar file but since you do not have a mail id in your profile i cannot do it.

[vaibhav waghmare]

hi rahul,
thx for the enthu you shown towards me! Somehow i've got the ujc.jar file and even i added it to my Classpath. But my problem isn't solved yet ! still my test client gives the same error! do you think there is something wrong in my development steps?
thx for the reply.
well my mail id is : [e-mail]

[Rahul Mahindrakar]

Please change your profile to include your e-mail id. The profile link is available just under "Post New Topic button". Right Now i am busy with some work i will get back later.

[vaibhav waghmare]

------------------
love n regards,
-VaibhaV.

[daman sidhu]
