The enumeration.next() will automatically page through for you. Actually, maxBrowsePageSize is relevant only to the Queue.browse JMX and webconsole operation and limits how many messages can be browsed by that operation.
For normal dispatch (including dispatch to QueueBrowsers) the destination maxPageSize option can be relevant but as it defaults to 200 and you have only 4 messages, it will not effect your scenario. It determines how many persistent messages are in memory and ready for dispatch. You can experience a hung queue scenario if there are more than maxPageSize messags in a queue that do not match a selector. Best approach is to try and pull together a test case and open a jira for this. 2009/1/16 IBeaumont <ibeaum...@categoric.com>: > > Hi Gary, > > 1.
