Subject Re: [Spam: 5.0] Two brokers when embedding in Jboss
Date Wed, 14 Mar 2007 20:58:30 GMT

James,

Sugestion 1 did the trick. I changed the ra.xml from vm://localhost to
tcp://localhost:61616 and now I just have the embedded broker. 

I failed to test your second suggestion with the vm://nameOfYourBroker. Does
this mean the broker-config.xml needs a transportConnector configured like
so?

<transportConnector uri="vm://embedded" discoveryUri="multicast://default"/>


I am wondering what the side-effects of the first action are. Does this mean
that I loose the efficiency of the vm transport, because the tcp network
roundtrip is introduced?

Cheers,
Jan Arend
