seam 3 identity on a cluster

kgoedert Aug 20, 2012 9:53 AM

Hi,

Everything that I read on the forum tells me that I should have no problems running a seam 3 application o jboss cluster. I also read on seam security docs that the Identity is a session scoped bean. So I assume that it would be replicated between nodes. Am I wrong in my assumption?

If I log into my application and the request goes to node1, I login without problem. If I shut the node down, my request goes to node 2 as expected but I am not considered to be logged in anymore.

What can be wrong?

Thanks for the help.

Kelly

JSF is stateful, so you need to have sessions replication if you're going to have clustering. So all of your session beans get replicated, if a node dies, another will be able to serve the request. Don't expect to scale much with stateful designs.

If you want to avoid this, you can put a hash of user identity in cookie and check on each request, so you move to stateless. JSF 2.2 will have a stateless mode.Stateless is the way to go but it's hard to acheive.
