Launchpad errors installing V5.0 on Linux from downloaded CD install image
 Technote (troubleshooting)
 
Problem(Abstract)
Installing WebSphere® Application Server V5.0 from a downloaded installation image (usually a .tar file) might result in a Launchpad error indicating that the Java™ Developer Kit cannot be found. This is often the result of symbolic links that get broken when extracting the .tar file using the Unix® tar command.
 
Resolving the problem
Problem:
When using an installation image instead of a product CD created by IBM, it is possible to break the symbolic links in the tape archive (tar) file during extraction. This results in errors during the installation.

The typical error is Launchpad: JDK not found, but Java tracebacks have also been reported.

Solution:
The Unix tar command has options to preserve symbolic links and file permissions. Use the proper options during extraction of the .tar file. Here is the recommended syntax:
tar -xvhpf filename
where:
  • -p resorts file permissions,
  • -h forces follow of symbolic links

Example:
tar -xvhpf /tmp/c45d9ml.tar
