Jars in web-inf/lib not in classpath

Question

          Hello,
          I am building a web application where I wish to use third party jars.
          (specifically cos.jar and log4j.jar)
          AFAIK when you place these jars in the web-inf/lib directory of your application
          they should then be included in the application classpath.
          However this does not seem to always work. I am using Weblogic 6.1, no service
          pack.
          Eventually I got it to work by adding a manifest to my EJB jar file with the classpath
          pointing to the jars and including the jars in the ear file.
          Has anyone else had any issues with this?
          Thanks,
          James
          

Answer 1

James,
          Yes, I've had troubles with WLS 6.1.2 finding the classes in my jar files
          that are stored in WEB-INF/lib when deploying as a .war file. The funny
          thing is that when I deploy to a WLS 6.1.0 running on two other machines
          (one solaris, one linux), I don't see this problem.
          My servlets all extend the webmacro WMServlet class, which is found in
          WEB-INF/lib/webmacro.jar. When deploying my web app, grems, I see the
          following behavior.
          On WLS 6.1.0 (running on solaris), the server unjars the WEB-INF/lib files into
          ".wlnotdelete/WEB-INF/_tmp_war_myserver_myserver_grems". That directory
          contains a jar file for each one in my .war files WEB-INF/lib directory.
          On WLS 6.1.2 (running on Solaris), however, the server just doesn't seem to do that.
          Instead, it creates
          ".wlnotdelete/WEB-INF/_tmp_war_myserver_myserver_grems/WEB-INF/lib". Not
          only that, but it doesn't put any of my jar files into that directory.
          Notice that it create the WEB-INF directory twice for some reason.
          Needless to say, any class which uses a class from one of those jar files
          bombs spectacularly with a ClassNotFound exception. This is extremely
          frustrating and any help would be greatly appreciated.
          Thanks,
          Bobby
