We are using session Beans in our project, to make portability across different servers (Jboss, Weblogic, Websphere) is any modifications required in the deployment descriptor specific to application servers? Currently we are using jboss application server
Yes, you can re-use ejb-jar.xml as it is but you will have to re-create( there are migration tools to get this done) vendor specific deployment descriptors. But you need to avoid using vendor specific stuff in your EJB.
