You are right, the resource-ref are mentioned per EJB. But those resources can still be used across EJBs. I think this is determined by the res-sharing-scope(which can take values 'Sharable' or 'Unsharable') attribute inside the resource-ref element. The dtd will provide more details. By default this value is Sharable which i guess means that the resource can be accessed across the EJBs. anonymous wrote : | When looking up such resources, out of the following two way which is the best practise? | | lookup gicing full path | ctx.lookup("java:comp/env/something/something"); | | or | lookup giving only relative path | ctx.lookup("something/something"); The second one is not going to work. When you specify a resource-ref, the objects will be bound in the java:comp/env namespace. So unless you specify that prefix, the lookup code will not be able to retrieve that object for you.
