hi all.

I'm facing a lookup can't find error for about a day....

I have created a EAR file called "Ad.ear".
Inside of the EAR file, there is a JAR&WAR files.
In Jar file, I have a Remote interface called "ResetObj" and implemented Stateless Session bean called "ResetObjBean".

Here's what I'm tryin to do.

I created another EAR file called Ad2.ear which only contains the Servlet.
From the servlet, I'm tryin to call the Remote Session Bean like this:

Context ctx = new InitialContext();
ResetObj rst = (ResetObj )ctx.lookup("Ad/ResetObjBean/remote"); //this part fails
rst.resetObject();

but the prob is that it gives me following error:

java.lang.NoClassDefFoundError: ad/session/flow/ResetObj
