Thank you Vicky , for the reply. Just to add to my question, changing conn parameters is exposed as a feature. So for end user the operation should after performing the operation , he should either a success or failure I mean to say , he should not get either a 404 or any exception as appl is redeploying. Is there any JBoss JCA API to achieve through code, we have a seperate a package for all container related operations , so I am free to use any JBoss API's there. Please let me know if there are any such Jboss API's to refresh the conn obj registered with JNDI name.
