WebLogic Server 5.1 giving errors of code 500

Question

Hi,
          We have a system consisting of WebLogic Server 5.1 running on Sparc Solaris and
          JDK 1.2.2 that is going to go into production soon. It houses JSPs and some
          servlets (some of the servlets are JMS clients). The EJBs are kept on another
          Sparc Solaris machine with the same version of WebLogic Server and JDK.
          So far, the EJBs are running fine. However, it is noticed that after running for
          one or two days, the instance of WebLogic Server that houses JSPs would give
          the HTTP error code of 500 whenever it was contacted through a browser. The JMS
          clients in the instance appeared to have stopped, as they did not print out
          texts that were supposed to be shown whenver a message is received. The error
          code of 500 was given for both JSP and HTML accesses. The system would not
          recover from that condition even if it was left running for a few more hours.
          Attaching the WebLogic Server Console to the instance of WebLogic Server
          concerned did not reveal any possible cause, and the console appeared to
          function correctly by providing information on system threads and JSP names
          etc. weblogic.log, access.log and the console output (the messages written by
          WebLogic Server to the terminal where it was started) did not reveal anything
          unusual.
          Wondering if anyone has encountered the same problem. Will appreciate any
          help.
          Thanks in advance.

          Before upgrading to service pack 6 for WebLogic Server 5.1. After first
          starting up the WLS, a user would see our index.html, but then would see
          error code 500 when trying to access the first JSP. A user would have to
          hit the browser back button and try again and the first JSP page would come
          up.
          I would suggest that you see if service pack 6 will have any impact on your
          problem, and see if that helps your situation.
