Problem with Multiple Context Creation

Question

Hi,
We are facing a java.lang.SecurityException Invalid Subject
We need to create multiple Initial Contexts for a single thread.
Following is the Scenario
1) The user will access Servlet/Struts Action class which performs database call and EJB(one, two) calls with different Initial Contexts ( Credentials are different)
2) At the same time the Timer Task runs in back ground which is invoked from servlet load-on-startup and runs for every 1 min.
3) The Timer Task invoke an MDB this MBD will make an external EJB (three) call for business logic.
{color:#ff0000}Please Suggest me the Sequence of step I am expecting are correct or not{color}
1) The Timer Task will run in the same JVM where the Servlet/Action classes are loaded (WEB-CONTAINER)
2) The Thread created for Servlet/Action class will not be shared by Timer Task.
3) The Thread created for Timer Task and the MDB are different.
4) So the Servlet - Thread, Timer Task Thread and MDB Thread are different.
The Behavior of the Context is as follows according to Bea Document.

JNDI Contexts and Threads
How to Avoid Potential JNDI Context Problems (Please Refer this Paragraph)
I am closing the entire Context's immediately after lookup
Still we are facing this java.lang.SecurityException Invalid Subject Exception Problem
The Context of EJB which we are calling from MDB is sharing the Servlet/Action Class Context -- Credentials
Example_
{color:#ff0000}Servlet/Action Class Context Credentials -- are user1/pass1{color}
{color:#ff0000}EJB (three) Context Credentials -- are user3/pass3{color}
When EJB (Three) lookup is invoked it’s throwing the following Exception
*java.lang.SecurityException: [Security: 090398] Invalid Subject: user1*
Please advise to solve this problem
Thank You.
