Adrian, Could you please poste the URL where a resolution to the problem reported by David is detailed? I am having same problem - Do not want to send any message until all the messages have been queued, but cannot control that because if I createSession using "true" flag, none of the messages are delivered, whereas if "false" is used, messages are delivered and some are processed before the queueing is complete. Thank You, Abhay View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4106140#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
