JNDI lookup error
Shabbir Mala
which i am facing is -
1. I have made two EAR application and trying to use a bean from first
application in the second one. On Web deployment descriptor GUI, I am
trying to add EJB Reference in the References tab. I did added a new
reference and linked on 'Browse' button to select a bean. On click it
is not showing me the first application bean, but after adding
configuring the bean reference in the second application, i am not able
to see the bean in the beans list after clicking 'Browse' button. But
when i add my second application in the application.xml (EAR deployment
descriptor) i am able to see the beans from my first application. Is
this the right process which i am doing?
2. If i dont added the module in the EAR deployment descriptor as
explained in the first step and try to do a lookup by changing the
web.xml of the second application with the <ejb-ref> description, and
calling the EJB using - java:comp/env/ejb/VascoMain.. it throws an
error.
The Error is -

You cannot use java:comp/env.. if you do not add the reference to the
applcations web.xml.
I'm not sure i understood exactly what you did but try this:
create an ejb-client jar, from the ejb project you want to call to ( if
app1 uses app2 than create ejb client jar from app 2) you can do this
by right clicking the ejb project.
You can add the ejb client jar to the OTHER ear project. and to it's
build path. This should make the use of the second ejb possible from
the first one.
dont forget PortableRemoteObject.narrow.
good luck.

thanks again..
