I'm trying to migrate from 4.0.5 to 4.2, and I'm hitting problems with my datasources. I learned in this process that 4.2 does not support multiple local TX datasources (http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3988662). So, I changed my datasources to be XA's. But, now I get these warnings every few minutes for all three of my datasources. | 21:31:10,147 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, 28, 26, 1-7f000001:ba8a:469ed3e6:2097f000001:ba8a:469ed3e6:213 | My questions: What does this mean? What problems will this lead to? Is there an inexpensive solution? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4065634#...
