Sun GlassFish Enterprise Server 2.1 Release Notes

Highly available webapps deployed at “/” unable to resume in-memory replicated HTTP sessions (Issue Tracker 2972)


Highly available web applications deployed at “/” are unable to maintain any HTTP sessions when using in-memory replication as their persistence type.


Deploy highly available web applications that use in-memory replication as their persistence type to a context root other than “/”. If you want to make such a web application available at “/”, you may designate it as the default-web-module of the virtual server to which the web application has been deployed.
