Sharing httpsession object - this should be a FAQ

[binario]

Hi all,

This post has come up several times but I can't find an answer.

1) I have one ear that contains multiple wars.

2) I want to share the http session object across each war.

Is this possible.

PS - single node, not using JAAS. Using JBoss Tomcat 4 rc2.

I really think this should be in the faq by the way. It has come up loads:

Found the answer from tomcat's faq:

"7. How do I share sessions across webapps?

You cannot share sessions directly across webapps, 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 tomcat-user mailing list, whose archives you should search for more information.

Sharing sessions across contains for clustering or replication is a different matter altogether."

If my wars are all in a single ear, is there perhaps a solution using JBoss' single classloader for the one ear?

Any ideas/experience with this?

There must be some experiences :-)
