hi there .. we have developed a couple of domain objects and initially deployed them as an ejb3 package. Everything works out fine .... Sliming my configuration reveals that JBoss provides a dedicated hibernate deployment archive ( har ) . Question: When should i use the har deployment to deploy my domain objects and when can i use the plain ejb3 deployment and simply pack the domain objects into the package. thanks in advance thorsten View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4075120#...
