Scripts in VPD demo/sample does not run

Question

Hi,
I am trying to run the VPD sample in an alpha server runing Oracle9i on TRUE64 UNIX.
When i run the "create_context_package.sql" i got some error messages.
The user_id in the following cause the error.
SELECT customer_id INTO This_Persons_Id
FROM customers
WHERE user_id = SYS_CONTEXT('USERENV','SESSION_USER');
The scripts are also listed following, it is from technet.oracle.com,
CONNECT Oe/[email protected];
CREATE OR REPLACE PACKAGE BODY Context_Package IS
PROCEDURE Set_Context IS
This_Persons_Id NUMBER;
BEGIN
/* Record the fact that we are setting up a users context */
/* We do this as we need to look up the user in the employee */
/* table when they log on, and we do not want the employee */
/* security policy to interfere with this lookup */
Dbms_Session.Set_Context('OE','SETUP','TRUE');
IF SUBSTR(SYS_CONTEXT('USERENV','SESSION_USER'),1,2)='CU'
THEN
/* If User is a customer, check to see if they have been */
/* given access */
BEGIN
Dbms_Session.Set_Context('OE','ROLE', 'EXTERNAL');
SELECT customer_id INTO This_Persons_Id
FROM customers
WHERE user_id = SYS_CONTEXT('USERENV','SESSION_USER');
Dbms_Session.Set_Context('OE','PERSONS_ID', This_Persons_Id);
EXCEPTION
WHEN NO_DATA_FOUND THEN
/* Customer has no access, so set a dummy id */
Dbms_Session.Set_Context('OE','PERSONS_ID', 0);
END;
ELSE
BEGIN
/* User is not a customer, therefore they must be an employee*/
/* Set their Employee Id */
Dbms_Session.Set_Context('OE','ROLE', 'INTERNAL');
SELECT Employee_Id INTO This_Persons_Id
FROM Employees
WHERE User_Id = SYS_CONTEXT('USERENV','SESSION_USER');
Dbms_Session.Set_Context('OE','PERSONS_ID', This_Persons_Id);
EXCEPTION
WHEN NO_DATA_FOUND THEN
/* No Employee Id found, set a dummy Id */
Dbms_Session.Set_Context('OE','PERSONS_ID', 0);
END;
END IF;
Dbms_Session.Set_Context('OE','SETUP','FALSE');
END Set_Context;
END Context_Package;
SHOW ERRORS
BTW, I am not sure if i need OID for VPD or for this example. Thanks for any help, tip, or reading document.

I got solution:
Re: Can't access remote EJBs (GF3.1)
I followed the instructions from http://www.java.net/node/676636
and changed "/etc/hosts" file:
1) commented out the "internal" IP addresses in the first two lines
2) and added a the external IP address
#127.0.0.1 localhost
#127.0.1.1 lennyserver
192.168.0.202 lennyserver
The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
Now the InitialContext.lookup() can find the bean.
