    Can't detect Java versions on Mac

    843804
      Hi,

      I recently upgraded my Mac from Panther to Tiger. When I typed java -version, I saw that my Mac used 1.4 as my default. I changed the java version manually by copying the files from /System/Library/Frameworks/JavaVM.framework/Versions/1.5 to
      /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK

      Everything seemed fine until I tried to start /Applications/Utilities/Java/J2SE 5.0/Java Preferences.app and also DbVisualizer (a database visualization tool). The error I get is:

      Could not launch the application because it requires a version of Java that is not installed.
      This application requires Java 1.4 or later, but only the following Java versions are installed: . Updating to a newer version of Mac OS X may resolve this.

      I have the following settings:
      "which java" results in: /usr/bin/java
      and "java -version" results in:
      java version "1.5.0_05"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_05-83)
      Java HotSpot(TM) Client VM (build 1.5.0_05-48, mixed mode, sharing)

      I think the errror message only appeared after I re-started my machine. Did anybody experience this problem before?
      Thank you for any help in advance!
      Mira
