Hi guys, I have tried the method on JBM 1.4.0 SP1, and I am still unable to get messages using listAllMessages when a message consumer is connected to the queue. Is there any way to monitoring queue content in JBM when the queue is actively consumed by message consumer? Thank you in advance. Best Regards, Hendra p.s. JBoss Server used is 4.2.0.G.A View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4102891#...
