  • If you have customised web pages follow the instructions below for updating them.
    

Upgrading JET 3270 on your web server

If you installed an older version of JET 3270 on your web server, follow these steps to upgrade it.

• Download one of the JET 3270 archives to your workstation.
  
  
• Expand the archive into a temporary directory on your workstation.
  
  
• Transfer the following files from the applet directory to the web server:
  
  
  • JET3270.jnlp (Java Network Launch Protocol file)
  • JET3270Key.jlk (Your licence key file)
  • JET3270J.jar (JAR file)
  • bell.au (audio file)
  • jet164.jpg (JET logo image file)
  These are binary files, except for JET3270.jnlp, so set the binary option if your file transfer package supports it.
  
  
• If you are not using a customised web page to load JET 3270, transfer the Shortcut.htm file from the applet directory to the web server.
  
  
• If you want users to view the JET 3270 documentation, transfer all of the document directory to the web server.
  
  
• Delete from the web server any files from the old JET 3270 version still present. Files that have not just been transferred (see above) and are not your customised web pages or your image files are probably from the old JET 3270 version.
  
  
• If you have customised web pages follow the instructions below for updating them.

Updating customised web pages

• Copy the customised web pages to the appropriate directory, renaming them to avoid overwriting files from the archive.

Upgrading JET 3270 class files

Once you have upgraded JET 3270 on your workstation or web server, your JET 3270 users should restart their browser to install the new class files on their local file system and use the new version.
