A way to discard messages via a CBR destination?

[ldimaggio]

Is there a way to specify - I'm assuming in jboss-esb.xml - that when a message reaches a destination as defined via a content based router, the message should simply be discarded, and not forwarded to a(nother) queue? Is there something analogous to a /dev/null destination?

Well I'm not sure how you would 'know' whether the message was delivered, so I'm not sure what you mean. But you may want to check out either the

DeadLetterChannel: http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossESBDeadLetterService

or the
MessageFilter:

hope that helps,

Thanks Kurt - for yet another rapid answer!

One problem - I cannot find org.jboss.soa.esb.actions.MessageFilter

I'm running MR2 - is there a newer download? Funny - I googled for it and only found one reference - http://wiki.jboss.org/wiki/Wiki.jsp?page=JBossESBMessageFilter

Is this the correct class name?

21:11:29,328 WARN [ServiceController] Problem starting service jboss.esb:deployment=Quickstart_message_filter.esb

But - this works great:

service-category="JBossESB-Internal" service-name="DeadLetterService"

In MR2 I think it's called org.jboss.soa.esb.actions.ContentBasedFilter.
