I'm getting the following logging message quite often in my application which makes heavy JMS usage (persists messages to the database): | 17:38:46,640 WARN [loggerI18N] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] [com.arjuna.ats.internal.jta.resources.arjunacore.norecoveryxa] Could not find new XAResource to use for recovering non-serializable XAResource < 131075, 29, 27, 1--3f57febc:10fd:48901126:17f-3f57febc:10fd:48901126:182 | I've browsed the forums and internet and couldn't find exactly what this message is about. My questions are: * What exactly is the problem? * What is the root cause of it? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4168312#...
