Unfortunately in all of my research (looking at Deployment in J2EE,
WebLogic, Websphere and JRun) you must rely, to some degree, on the
container for their preferred JNDI lookup scheme.
For instance, the J2EE implements it this way:
Context initial = new InitialContext();
Object objref = initial.lookup("BeanAliasFromDeployTool");
Whereas, WebLogic uses:
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.TengahInitialContextFactory");
try{
ctx = new InitialContext(env);
...
}
Essentially, you're going to have to depend on the eventual deployment
target/container in order to implement the proper JNDI naming service. Of
course, if you wanted to abstract this out and use some sort of abstract
interface, I guess you could defer this logic to run-time as opposed to
compile time.
FWIW!

Hi,
good point, to you have portability, use the following:
Context context = new InitialContext();
UserHome userHome =
(UserHome)context.lookup("java:comp/env/ejb/sample10a.UserHome");
final User user = userHome.findByPrimaryKey(name);
But it only worked inside another EJB, I tryed it on a servlet and it
doesn't worked.
