JBoss Transactions

[annapurna]

I am not sure if this is the right forum to post this question...
well what I want to know is a way I can see what JBoss does in terms of transactions. I want to find out when a transaction has started and when it is ending. Is there a method in JBoss which tells that a transaction has started and another one which tells the transaction has ended.

Actually I was trying to play with transactions for a bean managed entity bean. I changed the transaction attribute to never/notsupported/required/requiresnew but I dont find the difference in terms of calls to EJBStore and EJBLoad which I heard to be transaction depenedent.

Let me know if anyone have answers.....

Thanks in Advance,
Anna.

On http://localhost:8080/jmx-console look for
jboss.system:type=Log4jService,service=logging

In that MBean look for setLoggerLevel()
in the first parameter put
org.jboss.ejb.plugins.TxInterceptorCMT
in the second
TRACE

You should get the information you want in server.log
