[ https://jira.jboss.org/jira/browse/JBMESSAGING-1729?page=com.atlassian.ji... ] Howard Gao commented on JBMESSAGING-1729: ----------------------------------------- This is expected behavior. The reason you can list the messages because the messages are being delivered to the subscriber side. Unless you close the connection or the session. The amount of messages that JBM delivered to a consumer in one batch is controlled by PrefetchSize attribute of connection factory. default is 150. It can be set to as small as 1. Using default 150 value, the first time you need to send more than 200 messages to be able to see something returned by listAllMessages() if the consumer (subscriber)'s session and/or connection keeps open. I'll close this issue by rejecting it. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: https://jira.jboss.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
