Subject [jira] Commented: (AMQ-2280) stomp: Transport failed: java.io.IOException: Unexpected error occured
Date Fri, 07 Aug 2009 08:22:35 GMT

    [ https://issues.apache.org/activemq/browse/AMQ-2280?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=53520#action_53520
] 

Aleksandar Ivanisevic commented on AMQ-2280:
--------------------------------------------


Just to confirm that I have split the sending and receiving part of my client into separate
connections and that appears to have "fixed" the problem.

I still don't see anything both in the STOMP spec and common sense that would be against mixing
transacted and non-transacted statements in one connection, so IMO this is a bug in AMQ STOMP,
not in my usage (if we don't count sending a destination in BEGIN frame which is clearly an
error).
