Subject Re: ActiveMQ questions
Date Fri, 08 Aug 2008 18:13:07 GMT

Regarding #1, would you please point me to some instructions or examples?  I
have a 4 appservers running on different computers and I'd like to install
an ActiveMQ on a 5th computer and have the 4 appservers sending/receiving
message from AMQ.

Thanks much
