I too use WebLogic 6.1 and I use to have my struts.jar (and everything else struts and Jakarta) in my war file's WEB-INF/lib directory and things seem to be ok, as long as all I was doing was JSP/Servlet stuff. However, when I tried to make my EJBs use the commons-logging.jar I had problems because as I learned the WLS EJB class loader does not see the WAR file's WEB-INF/lib; so I looked around and found that for 3rd party jars that are shared by JSPs and EJBs can be made available to the class loader by way of the EAR's manifest. I listed all my 3rd party jars separated by spaces in the EAR's meta-inf/Manifest.mf as follows:
Manifest-Version: 1.0 Class-Path: commons-logging.jar commons-beanutils.jar commons-collections.jar commons-dbcp.jar commons-digester.jar commons-fileupload.jar commons-lang.jar commons-logging.jar commons-pool.jar commons-resources.jar commons-services.jar commons-validator.jar display.jar jakarta-oro.jar jdbc2_0-stdext.jar log4j.jar struts.jar commons-logging.properties Then I placed all those jars right at the top of my EAR file structure (right up there with the myAppWAR.war and myAppEJB.jar files). I also put the same Manifest.mf entries in my myAppEJB.jar file and my myAppWAR.war file, but I don't know if that was really necessary or not. After that things seem to work ok for me (for now).

My environment is Weblogic 6.1 SP3 (Win 2000) running Struts 1.1 Beta 2. With Struts alone via war deployment itself...it works great with this message: - <Nov 22, 2002 3:54:09 PM SGT> <Notice> <Management> <Application Poller started for development server.> [ChangeAwareClassLoader] : Name is : META-INF/services/org.apache.commons.logging.LogFactory 0 [Thread-2] INFO util.PropertyMessageResources -

Others say it's fix by adding a classpath to the manifest file like this: - Manifest-Version: 1.0 Created-By: Apache Ant 1.5 Class-Path: commons-beanutils.jar commons-collections.jar Class-Path: commons-dbcp.jar commons-digester.jar Class-Path: commons-logging.jar commons-pool.jar Class-Path: commons-services.jar commons-validator.jar Class-Path: jakarta-oro.jar struts.jar No, my Weblogic classpath hasn't got Struts.jar on it. Anyone has got any other suggestion, please?
