The session pool size is controlled by the "maxSession" activation configuration property. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/591722#591722] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
