Hello, Any file which you put in the deploy directory will be deployed by JBoss. I am also using a similar kind of design where i build a dynamic datasource. For the next request which comes in check whether the old datasource string and the new datasource are not equal then if they are not equal then i deploy the new datasource. And i also sleep if i deploy the datasource for sometime . So that the new datasource is deployed. But i never change the jndi name of the datasource. I hope this must help you. Take Care, Subbu View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3987863#... Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&a...
