This is documented as a note in the reference documentation. Websphere's statefull session bean timeout default is 10 minutes. You can adjust this using Websphere specific deployment descriptors.

Take a look at the websphere docs site for details on how to do that. -Jay View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4129660#...
