[wildfly-dev] How to configure Wildfly to use the InMemorySessionManager instead of DistributableSessionManager?

[Eric B]

Hi Stuart,

Strangely enough, my web.xml does not have distributable defined.

I managed to get the InMemorySessionManager working by using a servlet
extension, but I can't help but think I'm using a sledge hammer to
configure it that way.  I can't believe there isn't another way to enable
non distributable sessions.

My application is a JEE ear with 2 web apps (using a shared session cookie)
and an EJB package if that makes a difference.

Thanks

Eric

If you remove <distributable/> from your web.xml you should just get the
InMemorySessionManager.
