updated-jar in jboss deploy director doesnt take effect?

[d10n2000]

hi all,

please help me,
i make a MDB java classes, jar it (i give it name mtstatus.jar), then deploy it by copying to $JBOSS_HOME%/deploy, then I call it, it works because
it generates some System.out.println ("updated on 1614")message on the onMessage() method that i put in the MDB class.

Then I make modification to the MDB java class, replace the "updated on 1614" with "updated on 1620"
re-jar it again with the same name, re-deploy it again, then call it, but what i have is really supring, it still prints "updated on 1614" instead of "updated on 1620".

I've tried all the possible combination that I have in mind. I stop the jboss first, then delete the jar from $JBOSS_HOME%/deploy and also delete $JBOSS_HOME%/deploy/Default/mtstatusman.jar, then I re deploy the jar, but it still has no effect.

Is there anyone else who's got this behaviour?
Please help..
I'm using JBoss-2.4.4 under Windows 2000.

Thanks a lot.
