Message:
Our enterprise app which used SIBus route for internal messaging, was asked to 
be changed to work with MDB using WebSphere MQ(external messaging requirement 
had also come up). 

This application uses ejb-2.1, and is now deployed on WAS-7.0.0.23, and is 
configured to use JMS-Activation to work with the WMQ destination. Our customer 
initially did not have the WMQ infrastructure, so with the WAS 
configuration(JMS-Activation) done(JMS Resources) for our app, the app wouldn't 
start as the JMS Activation enabling failed. To correct this, we had suggested 
using WAS_EndpointInitialState(value as INACTIVE) JMS Activation custom 
property referring 
http://www.ibm.com/developerworks/websphere/library/techarticles/1104_madgula/1104_madgula.html?ca=drs.

Are there other ways to help protect the app deployed from failing to start up, 
because the JMS destination(WMQ) is unavailable, that is, ways to make the app 
independent(with respect to app start) of the JMS resources it use? In 
Messaging Listener Port based WAS configuration, it had the "Maximum number of 
retries" option, what is its equivalent in JMS Activation specification, that 
is, how message sending failure is to be handled?
