Hello all,

I have a J2EE app deployed in Jboss and most of the processing is done within 
JMS components (via message-drive beans). I've heard user complains saying that 
the first time a particular jms message is processed, processing times are 
significantly slower than subsequent runs (8 seconds vs 200 milliseconds). I am 
not sure where exactly the bottleneck could be.

Can anyone please:

1) suggest how to profile the app run to see what part of the code takes long 
to execute upon first run?

2) ideas on determining the bottlenecks during first time execution

3) give pointers on pre-loading J2EE components, etc 

Thanks a lot
James
