How to make a context child of an existing context

[Sivaraman Lakshmanan]

Hi,
I have 2 context in Tomcat say Context A and Context B. I want some session variable of A to be accessed by B. So I thought of making the context B as a child for Context A. Can some one help me how to achieve this.
Any help on this will be very much appreciated.

There is no provision in the spec or in Tomcat for nesting contexts.
If the two need to interact that closely, then they should be one context.

Hi,
Thanks for your reply. But is there any way to share information between context in tomcat 4.1.

[B]How do I share sessions across web apps?[/B]
You cannot share sessions directly across web apps, as that would be a
 violation of the Servlet Specification. There are workarounds, including
 using a singleton class loaded from the common classloader repository to
 hold shared information, or putting some of this shared information in a 
database or another data store. Some of these approaches have been
 discussed on the [WWW] tomcat-user mailing list, whose archives
 you should search for more information.
 
 
Sharing sessions across containers for clustering or replication
 purposes is a different matter altogether.
 

Obviously, this doens't make for an easy distribution of your app.

If they need to share session information, why did you make them two seperate contexts?
