JNDI Exception while trying to create home object

Question

Hi everyone,
I'm trying out a test application to create a home object in a remote computer. I'm using the SUN Ref-Impl v1.3 . I ran the small code below,
try {
Hashtable env= new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory");
env.put(Context.PROVIDER_URL, "iiop://localhost:1050");
env.put(Context.SECURITY_PRINCIPAL, "guest");
env.put(Context.SECURITY_CREDENTIALS, "guest123");
InitialContext ic= new InitialContext(env);
Object objRef= ic.lookup("jdbc/eVDB");
System.out.println("DB conn success!");
} catch (Exception ex) {
ex.printStackTrace();
System.out.println("Unable to conn DB... "+ ex.getMessage());
I successfully accessed this Database object wrapped in an entity bean through .jsp .
But when I ran the above code the follwing exception was emitted,
javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0
     at org.omg.CosNaming.NamingContextPackage.NotFoundHelper.read(NotFoundHelper.java:72)
     at org.omg.CosNaming._NamingContextExtStub.resolve(_NamingContextExtStub.java:402)
     at com.sun.jndi.cosnaming.CNCtx.callResolve(CNCtx.java:440)
     at com.sun.jndi.cosnaming.CNCtx.lookup(CNCtx.java:492)
     at com.sun.jndi.cosnaming.CNCtx.lookup(CNCtx.java:470)
     at javax.naming.InitialContext.lookup(InitialContext.java:347)
     at TestJNDI.main(TestJNDI.java:26)
Unable to conn DB... null
========================
If anybody can help me I would be most grateful. Thank you.

i added the j2ee.jar and the out put changed.
when i write,
ic.lookup("eV/CheckLogin");
it successfuly created the home object.
But when I added a database JNDI reference it failed,
when i wrote,
ic.lookup("java:comp/env/jdbc/eVDB");
the following exception occures,
javax.naming.NameNotFoundException: No object bound for java:comp/env/jdbc/eVDB
     at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:116)
     at javax.naming.InitialContext.lookup(InitialContext.java:347)
     at TestJNDI.main(TestJNDI.java:30)
and when i put,
ic.lookup("jdbc/eVDB")
the previous exception occures,
javax.naming.NameNotFoundException. Root exception is org.omg.CosNaming.NamingContextPackage.NotFound: IDL:omg.org/CosNaming/NamingContext/NotFound:1.0
     at org.omg.CosNaming.NamingContextPackage.NotFoundHelper.read(NotFoundHelper.java:72)
