Unable to get 'InitialContext' using Java Client in Oracle App 10.0.2.0

Question

Scenario & Problem Description: Unable to get 'Initial Context' using Simple Java Client in Oracle Application Server 10.0.2.0
I'm having an issue while I try to initialize the Initial Context for an EJB lookup from a simple Java Client [local lookup], but the same code snippet works fine when I try from Servlet. I have enclosed the Exception Stack Trace and the Code Snippet for your reference.
1. .NET Client ---> Servlet --> LookupUtility --> EJB --> DB - Issue
2. .NET Client ---> Servlet --> EJB --> DB - Works
Exception: java.lang.InstantiationException: Error communicating with server: Lookup error: javax.naming.AuthenticationException: Invalid username/password for Config (guest); nested exception is: nested exception is: Exception in InitialContext: javax.naming.NamingException: Lookup error: javax.naming.AuthenticationException: Invalid username/password for Config (guest) at com.evermind.server.ApplicationClientInitialContextFactory.getInitialContext(ApplicationClientInitialContextFactory.java:149)

Code Snippet:
* This method returns the Configuration for the properties set.
public ArrayList getConfiguration ( ) throws Exception {
ArrayList arrayList = null;
try {
Context context = getInitialContext();
System.out.println("Context : " + context);
Object home = context.lookup("java:comp/env/ejb/com.seagate.edcs.config.ejb.ConfigSessionEJBHome");
System.out.println("Object home : " + home);
ConfigSessionEJBHome configSessionEJBHome = (ConfigSessionEJBHome)PortableRemoteObject.narrow(home, ConfigSessionEJBHome.class);
System.out.println("ConfigSessionEJBHome configSessionEJBHome : " + configSessionEJBHome);
ConfigSessionEJB configSessionEJB =(ConfigSessionEJB)PortableRemoteObject.narrow(configSessionEJBHome.create(), ConfigSessionEJB.class);
System.out.println("ConfigSessionEJB configSessionEJB : " + configSessionEJB);
arrayList = configSessionEJB.getAllConfig();
System.out.println("Context : " + context);
} catch (Exception ex) {
System.out.println("Exception Occured");
throw ex;
return arrayList;
* Get an initial context from the JNDI tree.
private Context getInitialContext() throws NamingException {
try {
Hashtable hashtable = new Hashtable();
hashtable.put("java.naming.factory.initial", "com.evermind.server.ApplicationClientInitialContextFactory");
hashtable.put("java.naming.provider.url", "ormi://seagate.mil-shivas-270.am.ad.seagate.com/home"); // if we won't specify the port, it considers the default port
hashtable.put("java.naming.security.principal","ias_admin");
hashtable.put("java.naming.security.credentials","ias123");
return new InitialContext(hashtable);
} catch (NamingException ne) {
System.out.println("Exception in InitialContext.");
throw ne;
Note:
1. The user "ias_admin" & password "ias123" are the credential provided for the 'Admin' while installing the Oracle App Server and using these credentials I'm able to bring the Admin Console. Also, added new user 'guest/guest' - assigned this user to the 'admin' group ...
2. Since its a local lookup, there is no need to specify the credentials, but at runtime a dialog box pops up prompting to enter the 'userid/password' and when I enter the crendtials, I get the exception as stated. [In case of Servlet - EJB lookup, I'm not specifying any credentials]
Are there are any configuration parameters which I need to provide in any of the .xml? Could you please let me know the fix for the same.
