PackRat won't start :

  • Windows Users :
Open a Command Prompt (Click on Start, then run.  When the Run Dialog opens, put cmd in the text field, then click "OK")
From the Command Prompt type java then press the Enter key.
  • If results from the java command are : "java' is not recognized as ......", then java is not installed, please follow this link and install Java, then re-start PackRat©.
  • If the results from the java command are : "Usage: java [-options] ....", then java is installed, please contact us for Assistance.







  • Unix Users :
Open a Command Prompt/Shell
From the Command Prompt type java then press the Enter key.
  • If results from the java command are : "command not found", then java is either not installed, or not in your path.
        To determine if Java is installed under your own directory, issue the following commands :

              cd
              find . -path "*/bin/java" -print 2>/dev/null

        The results of the find command should give you the full path to the location of java, if no results return, then java is not installed under your own directory.  You can either look for java  in the system directories, or download a java distribution here.

        To determine if Java is installed elsewhere on the system, issue the following commands :

              find / -path "*/bin/java" -print 2>/dev/null

        If neither command yields any results, then java was not found on your system.  Please download and install a copy from here.

       Once java is installed and you have located its path, you can either add Java to your path (recommended), and start PackRat with :

              java -jar path/packrat.jar

 - or -

       If you choose not to add Java to your path, you can start PackRat with :

              javapath/java -jar path/packrat.jar


      Where path is the directory where you installed/extracted packrat and javapath is the directory where java is installed.


  You can also use :

              cd
              find . -name packrat.jar -print 2>/dev/null

      To locate the path if you installed it under your home directory, or :

              find / -name packrat.jar -print 2>/dev/null

      If you installed it elsewhere on the system.

     Example start command :

             /usr/java/j2re1.4.2_05/bin/java -jar /home/john/TechNicholMojo/packrat/packrat.jar
