RE: Problems with JNDI lookups of ejb-ref-name defined inapplication-client.xml from a client application...
I think application-client.xml is broken in Orion. The whole purpose of
having application-client.xml is to be able to map a client written by one
vendor, to the EJB written by another vendor. Has any one been able to
"properly" use application-clientejb-ref to map ejb-ref-name to
ejb-link where both are NOT the same string?
Thanks.

RE: Problems with JNDI lookups of ejb-ref-name defined in application-client.xml from a client application...
Hia guys,
Here is a bit of my experience with this stuff - I found out that if I
have a regular Java client it's the ejb-jar.xml's ejb-name that is
being used to lookup the bean name without the comp/env. The comp/env is
only to be used by J2ee clients i.e. servlets or JSPs. For the J2EE
clients, it is the ejb-ref name that is used in the lookup.
It's weird as all hell !! But that how I found out about this. IN other
words whatever you are using for the Home's lookup will depend on the
type of client you are using. To recap - for Java clients use
lookup("beanName") for J2EE clients ("java:comp/env/beanName")
Try giving this a try
Good Luck

Just a sidenote, maybe it's your problem. From page 377 of Enterprise
JavaBeans, 2nd Edition (Oreilly):
"The ejb-link value must match one of the ejb-name values declared in the same
deployment descriptor."
That is, it's only valid if you're using an ejb-jar.xml to define multiple
beans.

RE: Problems with JNDI lookups of ejb-ref-name defined inapplication-client.xml from a client application...
You are exactly correct. This IS how it is working in Orion but this does
not seem to the correct.
Suppose you have an EJB that implements some STANDARD interface already
defined, deployed and used by many applications and from many places. You
buy a client application from a vendor who has implemented a new GUI to work
with this STANDARD interface. The vendor defines application-client.xml and
you need to augment it with ejb-link to point to the actual bean. The
vendor DOES NOT know what is the REAL PHYSICAL name of the bean which
implemented the STANDARD interface in your environment, so there is no way
for the vendor to do a lookup based on "beanName". The client vendor writes
his application to lookup on the value in ejb-ref-name.
If this is the way Orion is working, this appears to be somewhat of a
serious bug.
By the way, when I try to use "java:comp/env" from my client, I get the
following exception:
Exception in thread "main" javax.naming.NamingException: java:comp/env
namespace is only available from within a J2EE component
at
com.sun.enterprise.naming.java.javaURLContext.getComponentContext(javaURLCon

at javax.naming.InitialContext.lookup(InitialContext.java:350)

Should I record this as a bug, or does any one have other ideas?

Well, if that's the case, then what's the point of putting ejb-ref in to the
application-client? The client can just always lookup by absolute name
inthe JNDI namespace. And how would an independent client developer
possibly know the EJB names deployed in your custom environment?

JNDI lookups
Hi everyone, this might have been asked before, but I have a question regarding JNDI lookups. I tried the ConverterApp example that is in the J2EE Developer's Guide (Getting Started). So I used the J2EE deploytol and then deployed the ear in orion. In order to run the application Client I need to put both the client-jar and the EJB-jar in the classpath: CPATH=.;%ORION_HOME%\orion.jar;%ORION_HOME%\ejb.jar;%ORION_HOME%\jndi.jar;ap p-client-ic.jar;ejb-jar-ic.jar java -classpath %CPATH% ConverterClient If I don't put the ejb-jar in the classpath, the client doesn't run. So in this sense, it seems that the JNDI name lookup doesn't work!? Then how would I go about running a remote client that communicates with the ejb if such lookup doesn't work? It's possible that I misunderstood something. So any comments would be appreciated. thanks regards, Alex Alexandre J. Boudreau President, Directeur de Projets Fibro Movement Corp.
