i have an Application. The EJBs are bundled into a jar file and the web application is bundled to a war file and everything is bundled into an EAR file. I noticed whenever i make changes to my web application(Either to the Struts Files or the JSPs) I don't really need to restart my Server. but whenever i make changes to the EJBs i need to restart. I am using ANT by the way to build the Jars,Wars and EAR and also to deploy (copy) the ear to the deploy directory.
is there any settings i need to make to enable Hot deployment for EJB
You don't have to restart the server for the changes to take place. You can just redeploy that single application. Without redeploying the application, it's not possible to change the EJB classes on the fly. See if this helps:
