Hi Tim, we are not using a clustered connection. However, we read in Jboss documentation (see http://docs.jboss.org/jbossas/javadoc/4.0.3SP1/j2ee/javax/jms/Connection....) that "a JMS provider should attempt to resolve connection problems itself before it notifies the client of them". This probably means that JBM has some kind of automatic mechanism for resolving connection problems. Am i right? If so, do this mechanism ensure ordering of messages that are sent whilst JBM is resolving these connection problems? Another question : We have an Exception Listener that tries to recover a problematic connection. Can we be sure that messages recieved after our connection recovery are in order?
