java.lang.SecurityException: [Security:090398]Invalid
Subject

Hi 

I am getting this error when I am making an EJB method  which resides in a
different weblogic 9.1 server.

I have enaled the trust between my two domains. Set the required class path
settings. 

My client call is from a JSP , say client.jsp.
Here I get remote object of the EJB and calls the required method
Now 
1) My EJB calls are succesful when I DO NOT secure it

2) but when I make it  is secured , ie when I 
include the jsp in secured URL ie. under
<security-constraint><url-pattern>client.jsp</> in web.xml

 , it gives me the follwing error

 The stack trace is given below
java.lang.SecurityException: [Security:090398]Invalid Subject:
