    Discoverer Plus

    gervaipe
      I am trying to run Discovere Plus 9i and I am running into the following problem.
      Jinitiator loads the necessary files and then I get the error message :
      unable to load class oracle.disco5i, thus the applet does not load the page just hangs.

      This is from my java console:

      Downloading http://<Host>:7777/discoverer/plus_files/disco5i.jar to JAR cache
