ClassNotFoundException trying to load classes in a .war file inside an .ear file

Question

Hi. I've deployed an EJB2 enterprise app as an ear file on WebLogic 6
          without errors. The ear file contains web app and ejb components in war and
          jar files. The web component is set to be the default web app in the
          config.xml file. Everything deploys without error messages.
          My problem is that I get ClassNotFoundExceptions when I try to invoke a
          servlet (via its servlet-mapping) or do Class.forName() on any class file in
          the war file.
          I see in '.wl_temp_do_not_delete' that the ear file has been decomposed into
          the ejb jar and web war files. The war file is not 'exploded' into a
          directory structure, however (as the console.war is). Is this an error
          (should the class packages in the war file be 'exploded'?)
          I don't see a tag in the web.xml, config.xml, or application.xml that tells
          the server to explode the war file--is there one?
          Note that if I manually copy the exploded class folders into the
          '_tmp_war_myserver_myserver_<<webappname>>' directory (and not, curiously,
          into a WEB-INF/classes subdirectory of that directory), the servlets and
          other classes load correctly. Also, jsps and html files load just fine
          without exploding the war file.
          Note also that the server complains about not being able to find the
          classes, even though it reports that the decomposed war file is in the
          classpath. Is there a problem loading class files from a .war file (because
          the namespace is different, with root classes located in WEB-INF/classes
          rather than the .war file's root?)
          Also, in the application.xml file, what is the meaning of the
          <context-root></context-root> element? What should its value be? What if
          you leave it blank?
          Thanks for any help,
          Reid

Is there a way to add jar libraries to the Oracle JVM CLASSPATH? Is this the same as the system's CLASSPATH env. variable?
Thank you!

The package prefix in the code extract was correct - i.e. "oracle.aurora.jndi". A value of "oracle.aurora.jndi.*" would be incorrect.
The problem is that the context factory implementation specified (com.evermind.server.ApplicationClientInitialContextFactory
) can't be found, the mostly likely reason being that the library containing the class isn't on the classpath.
