Subject Re: Multiple war in Tomcat 7 using a shared embedded ActiveMQ
Date Mon, 05 Dec 2011 02:46:45 GMT
Hi Dysan,

I am not a tomcat expert but just looking at the server.xml file.  There is the concept of
a listener that you might want to consider as a way to start/stop the activemq broker.

Here is a pointer to the javadoc.

http://tomcat.apache.org/tomcat-7.0-doc/api/org/apache/catalina/LifecycleListener.html

It receives a lifecycleevent instance that you can use to determine in which cycle the tomcat
server is currently processing.  


Looking at the javadoc you should be able to determine which lifecycle event you should start
the broker on and which cycle event you should shutdown the server.

You could then define a mechanism to determine which connection information you should use
to connect to the broker.

This is just part of the general v7 javadoc located at:

http://tomcat.apache.org/tomcat-7.0-doc/api/index.html


Hope this helps,

--Claudio
