Hi All ...
I am getting this exception while deploying an ear which contains a call to the
entity bean from a session bean , does anybody have an idea where the things
are going wrong :

My code goes like this (I have put it in a servlet) ::
code:
// set the JNDI Properties
Properties props = new Properties();
props.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
props.setProperty("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
props.setProperty("java.naming.provider.url", "localhost:1099");
// Session mySession=
SessionManager.getManager().getSession("comics");
// ((JNDIConnector)((Session)
mySession).getLogin().getConnector()).setLookupType(JNDIConnector.STRING_LOOKUP);
// invoke the session bean object
try {
Context context = new InitialContext(props);
// DatabaseLogin login =
(DatabaseLogin)mySession.getProject().getLogin();
// javax.sql.DataSource ds = (javax.sql.DataSource)
context.lookup("java:system");
// System.out.println("Data Source "+ds);
// JNDIConnector connector = new JNDIConnector(ds);
// login.setConnector(connector);
src.FirstSession myBeabObj = (src.FirstSession)
context.lookup("sample123/FirstSessionBean/remote");
myBeabObj.sayHello(Name, Age, Dept);
PrintWriter pwWriter = response.getWriter();
pwWriter.println("Before calling Persistence");
// new entityCaller().persistEntity(Name, iAge);
pwWriter.println("After calling Persistence");
pwWriter.println("new
Deployment"+System.currentTimeMillis());
pwWriter.println("You submitted Age"+Name);
pwWriter.println("You submitted Age"+Age);
pwWriter.println("You submitted Age"+Dept);
// pwWriter.println("The Bean returned this
value"+myBeabObj.sayHello(Name , Age , Dept ));
System.out.println("Finished Transaction");
} catch (NamingException e) {
System.out.println("Exception Reached");
e.printStackTrace();
}// end of try catch block
