    Java.Lang.NullPoint.Exception in OWB Mapping

    384107
      Hello Everybody

      We are building Data Warehouse using OWB Repository 9.2.0.2.0. When we are validating or deploying the created map we are getting Java.Lang.NullPoint.Exception. This leads to blank screen. We are unable to recover the map. Sometimes, synchronization works to recover the map, but not all the times.

      Is there any solution to it?

          Bana,

          What is the version of the client you use? We have had some NLS related issues in early versions of the client (e.g. 9.2.0.2.8) that have been resolved later. You may be able to recover from your issues by applying a later patch (e.g. 9.2.0.4).

          Thanks,
          Mark.

              Bana,

              Is it possible for you to migrate to 9.2.0.4, available from metalink?

              Thanks,
              Mark.

                  Is it possible to solve the problem without migrating? I have the details of error as follows --

                    Bana,

                    Can you run <owb home>\owb\bin\win32\owbclient.bat explicitly and submit the last hundred lines or so from the log that you get in a separate window? This will help us try to identify the issue.

                    Thanks,
                    Mark.
