Can't run examples or how to unregister MBean in JBoss

[mambo]

Hello,

I tried to deploy seam examples to JBoss, but he answered with following stacktrace:

17:12:15,783 ERROR [MainDeployer] Could not create deployment: file:/C:/Programme/jboss-4.0.4.GA/server/default/tmp/deploy/tmp55634jboss-seam-booking.ear-contents/jboss-seam-booking.jar-contents/booking-ds.xml
org.jboss.deployment.DeploymentException: Trying to install an already registered mbean: jboss.jca:service=LocalTxCM,name=bookingDatasource
at org.jboss.system.ServiceCreator.install(ServiceCreator.java:103)
.......

I have this problem with Seam 2.1.1-GA and JBoss-4.2.3.GA, also i tried not deploy jboss-seam-booking-ds.xml, but then i getting this error:

org.jboss.deployment.DeploymentException: create operation failed for package fi

Looks like you are trying to deploy 2 datasources, both with the JNDI name bookingDatasource.

You need to ensure that your datasources are unique and only deployed once.

I not sure, but it looks like there is only 1 DS in that example. Error arised because i previously deployed and then
undeployed (ant) hibernate booking example and i guess it didnt cleaned up everything.
Now the question is how to remove mbean from AS without reinstalling latter.
