[JBoss-user] [EJB/JBoss] - Re: NullPointerException: at org.jboss.ejb.plugins.local.Loc

[tmike]

tks for the quick reply...

I am guessing if i use local interface, I can't test it by writing a simple client 
code(since it'll be run on its own vm)but I'll able to test it through a servlet 
connection or something.

if I let my servlet use remote ejb interfaces to access ejb beans, would it be 
optimized by jboss?...for ex. jboss will notice that servlet and beans exist in same 
vm, and do something about it(make it reference locally or something?)..

tks!!

[JBoss-user] [EJB/JBoss] - NullPointerException: at org.jboss.ejb.plugins.local.LocalHo

[tmike]

Hi guys, I have a few questions about how to look up local ejb

this is just part of my client code, which will be run as another java app.

ctx = new InitialContext(props);
System.out.println(MikeLocalHome.COMP_NAME);

MikeLocalHome home = (MikeLocalHome) ctx.lookup("MikeLocal");

a = home.create();

this is the exception I got when I try to do a create()
java.lang.NullPointerException
at org.jboss.ejb.plugins.local.LocalHomeProxy.invoke(LocalHomeProxy.java:110)

I've search various post on this topic from the forum. It says I can't reference a 
local EJB on the other JVM. What does other JVM means, if i start up JBoss app. 
server..it runs on its own JVM?...so, if I start up my client app, it's on another 
JVM?..even though it's the same computer

also, if I can't run local ejb on my client code, how would I test it?..I've seen post 
saying use remote interfaces, and JBoss will optimize the performance?..is that 
true?...does that mean I can let my servlet access ejb remotely(use remote interface), 
but JBoss will treat them as local ejb?...

btw, if I deploy my local ejb in a servelt and access, it works fine...

sorry for the long post...tks a lot!!
