How OSB pass Initial Context parameters to EJB

Question

For security reasons I have to pass a ticket (through initial context) to legacy system from OSB for calling EJB, below is a code
Hashtable env = new Hashtable(2);
env.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
env.put(Context.PROVIDER_URL, connectionUrl);
env.put(javax.naming.Context.SECURITY_PRINCIPAL, ticket);
env.put(javax.naming.Context.SECURITY_CREDENTIALS, "");
InitialContext ctx = new InitialContext(env);
Object homeRef = ctx.lookup("com.cih.services.contact.interfaces.IContactServiceRemote");
IContactServiceRemoteHome home = (IContactServiceRemoteHome) javax.rmi.PortableRemoteObject
.narrow(homeRef, IContactServiceRemoteHome.class);
IContactServiceRemote ejb = home.create();
Please let me know how we can pass Initial context parameter from Business service or proxy service to legacy system.
Thanks

Hi Russ
Yes, I've done this too. Basic SQL though will not allow the updating of a table inside a function, so we have to get clever. The trick is to use the PRAGMA AUTONOMOUS TRANSACTION command. Here's an example:
FUNCTION UPDATE_MYTABLE(P_VALUE IN NUMBER)
RETURN VARCHAR2 IS
PRAGMA AUTONOMOUS_TRANSACTION;
BEGIN
UPDATE SCHEMA_OWNER.MY_TABLE SET MY_VALUE = P_VALUE;
COMMIT;
RETURN('Done');
END UPDATE_TABLE;
When the update has been completed the Discoverer worksheet will respond with 'Done'.
Everyone: don't forget to grant EXECUTE on this function to all of the necessary users, including the EUL owner, and also don't forget to import the function using the Admin edition so that it is available for the users. You will also need to make sure that all necessary users have been granted the UPDATE privilege on the table.
I hope this helps
