HELP deploying an ear file... with details :)
i'm re-posting this with as many details as i can cough up. hopefully someone can shed some light on this issue
i have.
in a general sense, i am trying to deploy an ear archive that contains a "utility.jar". "utility.jar" is neither an ejb or a web archive. just classes i need.
i would assume that the problem lies in the correct configuration of the Manifest.mf files. i've read many articles, a tremendous number of posts in the forum and a tremendous number of hours trying different configurations.
i have a jar file that i want accessible to my application without putting it in the jboss classpath (to enable re-deployment). how do i allow access from a .war and from my ejbs. i thought the way to do that was to add the jar file (call it "utility.jar") to the .ear archive
and to the .war archive.
here's what i'm doing.
i have a jar file "bootstrap.jar" that is put in the jboss classpath
by adding a classpath extension in jboss.conf (works great).
i do this because i have 3 mbeans that get loaded on jboss startup.
that all works perfectly. i'm assumming this is the right way to go.
i have more base classes and utility classes that are used on all projects where i work that i put in a jar file
(call it "utility.jar"). these classes are necessary but since they
are not needed in the 3 mbeans, i can keep them out of the jboss classpath to enable re-deployment.
i have my application jar file which contains an ejb, and basically the rest of the application. i have the necessary deployment descriptor for the ejb (call it "application.jar"). also in this file is a meta-inf directory that contains a Manifest.mf file
i also have a web archive that contains all the web pages, the servlets, and a web-inf\lib and a meta-inf\Manifest.mf
"application.war"
i have my .ear archive that contains everything!
"application.ear"
So here are the details....
======ear archive=====
application.jar
application.war
utility.jar
application.xml meta-inf\
Manifest.mf meta-inf\
======================
and Manifest.mf looks like this (basically empty)...
======================
Manifest-Version: 1.0
Created-By: Ant 1.4
======================
and application.xml looks like this
===================================
<display-name>AFSP</display-name>
<web-uri>application.war</web-uri>
<context-root>/afsp</context-root>
application.jar
====================================
my application.jar has all my classes and
the following as well (because there is an ejb in the jar)
i'm assumming that putting an ejb in any jar file is
ok, as long as there is a deployment descriptor
as opposed to have one jar for the ejb and another
jar for helper classes?
========================================
ejb-jar.xml meta-inf\
jboss.xml meta-inf\
Manifest.mf meta-inf\
========================================
and Manifest.mf looks like this...
========================================
Manifest-Version: 1.0
Created-By: Ant 1.4
Class-Path: utility.jar
========================================
putting utility.jar in this Manifest.mf file
i thought was the key to making sure that utility.jar
was accessible to the application upon deployment
now for Application.war which contains
all the web pages, servlets, and...
=======================================
web.xml web-inf\
application.jar web-inf\lib
utility.jar web-inf\lib
Manifest.mf meta-inf\
jsp pages
images
=======================================
where the Manifest.mf looks like this...
=======================================
Manifest-Version: 1.0
Created-By: Ant 1.4
Class-Path: application.jar utility.jar
=======================================
originally, i did not think that these jar files should
be necessary in the .war archive but from reading posts
in the forum, apparently they need to be here too.
So that is the configuration of my application.
I wish i could say that i have a straightforward
problem but what i'm experiencing does not quite
make sense to me.
I get a NoClassDefFoundError
on a base class in utility.jar.
The class that is trying to instantiate the "bad" class,
is in the same package as the "bad" class, which is strange.
(See the NOTE in the stacktrace below)
The only nuance I can come up with is that the class that
is being instantiated is done so via
Class.forName("badclass.class");
I bring this up because I saw some post in the forum about
possible ClassLoader problems using Class.forName();
Here is the stacktrace. . .

I hope this question is of an appropriate format.
If i still have terrible voids in my details, please let me know.
