WEB-INF/lib files in war not in classpath

[n_ton]

I've seen a few posts about this problem, but no solution.

I have an ear that contains a war. In the war, I have some supporting jars in the WEB-INF/lib directory. When I deploy the ear, I get NoClassDefFoundError's for a class in one of the supporting jars. I would assume that would mean that the classpath didn't pick up the supporting jars in the WEB-INF/lib directory.

When I deploy the war itself, I get a ClassNotFoundException for one of the servlets in my web.xml. The servlet in question is also in a jar in the WEB-INF/lib directory of the war. Again, I would guess this is because the classpath didn't pick up the jars in the WEB-INF/lib directory.

I'm running JBoss 3.0.1 under the default configuration on Linux.

As I mentioned above, I've seen multitudes of posts with the same problem dating back to early this year. I'm surprised it hasn't been fixed yet. Is this really a bug? If not, where should I be putting these jars?

Thanx.

Hmm... you can try putting the servlet class in WEB-INF/classes. This works for me. However, I don't have any jars in WEB-INF/lib. Of course, the workaround is to put all the "dearchived" classes in the jars from WEB-INF/lib into WEB-INF/classes. By no means an elegant solution, but at least it works ;)

This really should just work. Perhaps you could post your ear structure (pointing out config files) so we can see what is going on?

While putting this reply together, I discovered the problem
where the servlet wasn't found when I deployed the war.
It turned out to be a spelling error in my web.xml. I
hate it when that happens.

However, I haven't been able to fix the ear deployment.


Here's my ear:

n_ton> jar -tf lib/myapp.ear
META-INF/
META-INF/MANIFEST.MF
META-INF/application.xml
myapp.war
myapp.jar

The application.xml looks like this:

<?xml version="1.0" encoding="ISO-8859-1"?>


<display-name>MyApp</display-name>


<web-uri>myapp.war</web-uri>
<context-root>/myapp</context-root>



myapp.jar




Here's my war:

n_ton> jar -tf myapp.war
META-INF/
META-INF/MANIFEST.MF
WEB-INF/
WEB-INF/lib/
WEB-INF/lib/jdom.jar
WEB-INF/lib/myapp.jar
WEB-INF/web.xml
translateTest.jsp


When deploying the ear, first I get:

JBoss then deploys my EJBs successfully and then I get (this is only part of
the stack trace. Let me know if you need to see more):

The class org.jdom.Element is available in jdom.jar in my war.

Your help is appreciated.

Classes inside the war is only reachable from inside the war. You are trying to use the jdom lib from an ejb outside the war.

You can either put the jdom.jar to be accessible "globally" in your server by putting it in .../server/default/lib (or whatever configuration you use).

If you want to have it inside the application, put jdom.jar directly in the .ear file and use the Class-Path: entry in the manifest files for the war and ejb to access it.
