Using the Java JAR command to open fix pack ZIP files is no longer recommended
 Technote (troubleshooting)
 
Problem(Abstract)
Previous versions of WebSphere® Application Server for UNIX® platforms were shipped in ZIP format. In the past, it was possible to use the Java™ JAR command to open these ZIP files. However, the JAR command breaks links in more recent fix pack images.
 
Cause
Previous installation images for UNIX platforms were packaged with ZIP files to save space. The JAR command breaks symbolic links and disregards permission data while opening ZIP file images.
 
Resolving the problem
Starting with WebSphere Application Server V6.0, all maintenance packs are shipped using the UNIX industry standard, TAR file format.
Complete installation instructions, including the use of TAR files, are provided in the WebSphere Application Server Information Center.

Current operating systems support other tools that open zip files, and system administrators are encouraged to use those tools to open zip files. However, if a tool for processing zip files is unavailable and it is necessary to use the JAR command to open a zip file, use the following process:
  1. Verify that the JAR file is on the PATH. One solution is to source the WebSphere Application Server setupCmdLine script as shown in the following example:

    cd /usr/WebSphere/AppServer/bin; . ./setupCmdLine.sh

  2. Use the following jar command to open the ZIP file:

    jar -xvf <filename.zip>


Hint: If the maintenance is planned to be applied to WebSphere Application Server V6.1, follow instructions for using the V6.1 Update Installer to complete maintenance pack installation.
