SUBJECT: [JBoss-user] My app deploys but lookup from servlet won't
work ! HELP !
Hello,
I'm a newbye with JBoss and J2EE deployment and it's the first web-app
I try
to deploy with JBoss ans EmbeddedTomcat (JBoss 2.2 + Tomcat 3.2.1).
I have made following archives :
- First, a jar containg my session beans and the enitty
interfaces
they're using (entites are in
another jar). When I test this SB with a simple client, it works
well
(without the following archives).
- Then, a war containg my servlets, web pages and the interfaces
of session beans.
- Finally, a ear archive with an application.xml for my modules.
During the deployment of this ear archive, everything seems to go
well.
I've got this messages :
...

This warning doesn't bother me (first time i deploy my session beans,
i
already get it but everything was fine).
When I launch my simple client, everything works fine !
But, when I try a servlet, I've got the following exception thrown :
2001-07-18 05:34:39 - Ctx( /frontend ): Exception in: R( /frontend +

.....
The code in my servlet is just a lookup to my session bean (and
interface
classes are in Web-inf/classes).
Why does it thrown a NoClassDefFound Error ? What is the $Proxy6 class
?
I've tried to package my application more properly by putting the
sessions
interfaces into another jar and by adding
a Class-Path entry to the manifest of my web module but I always got
the same result !
Could someone help me ? (it's gonna kill me ...)

Laurent
