Re: Exploded directory format in an EAR

Question

          I am now trying to deploy the ear file in v6.1 sp2. Has anyone managed to deploy
          an ear where util / third party classes are stored in a lib directory of the ear
          and referenced in EJB-jar manifest.mf files using the classpath header?
          ie as documented in bea weblogic server bible on page 614/615
          EntApp/
          accountEJB.jar
          accountManager.war
          /lib/
          xerces.jar
          xalan.jar
          log4j.jar
          /META-INF/
          application.xml

Answer 1

          This is hearsay again.
          These people did as you did no compression etc. they were able to put the application's
          utility classes in a lib but not the third party jars. They suspected that the
          ear where to big to deploy so they put all thirdparty jars in the system classpath
          and then the internal utility classes were loaded by using CLASSPATH in the manifest
          file.
          I gave up because I could deploy everything except servlets and I went back to
          exploded deployment. That bloody EAR thing took to much time.
          If you succeed in everything including warfiles with JSPs and servlets (those
          I was talking about only had EJBs)
          let me know.
          I also had a peculiar problem with EARs that a cascading stylesheet was not found
          in the ear but it worked in an exploded it worked fine
          Otherwise I must recommend Orion, which I had up and running in a matter of days
          when ported from WLS 5.1.
          Good luck.
