Excelsior JET 4.8 Maintenance Pack 3 Download

Excelsior JET 4.8 Maintenance Pack 3 (MP3) is a highly recommended update that fixes multiple customer issues. It supersedes Maintenance Pack 2 and incorporates all hotfixes you may have received from Excelsior Technical Support prior to June 26, 2007.

Excelsior JET 4.8 MP3 is a prerequisite for Windows Vista support.

WARNING: Maintenance Packs fix particular problems reported by Excelsior JET users and discovered by Excelsior test engineers after the release of the respective version of the product. They are tested on a representative subset of the test suite used during preparation of the original release. We therefore only recommend you to install Maintenance Packs in the following cases:

  • You have been advised to do so by an Excelsior support engineer;
  • You need to switch to a Java SE (micro)version supported through a Maintenance Pack;
  • You want to try a new technology from Excelsior that requires installation of a particular Maintenance Pack; or
  • You are experiencing a severe problem, such as compiler or application crash or incorrect application behavior.

Installation Instructions

MP3 installs on top of the original Excelsior JET 4.8, possibly with previous hotfixes applied. If you need to make a fresh installation, install Excelsior JET 4.8 first, cancel JET Setup, and apply MP3.

To update an existing Excelsior JET installation, launch the downloaded executable and follow the on-line prompts. Upon successful copying of Maintenance Pack files, JET Setup will launch automatically and apply the Maintenance Pack.

Profile Management

Installation of MP3 does obsolete your current profiles. You will have to refresh them before you may continue using Excelsior JET. Those profiles are backed up by JET Setup. If you rollback to the previous update level, they will be restored.

The procedure of profile refresh is as follows:

Windows

JET Setup is launched automatically upon successful installation of MP3. Select the profile that you want refreshed and click Refresh.

Linux

  1. Run JET Setup to display the list of profiles:
      jetsetup -show-profiles
  2. Locate in the list the outdated profile(s) that you need to refresh and write down their numeric indexes.
  3. For each profile index in your list, run JET Setup as follows:
      jetsetup -refresh-profile profile

    where profile is the profile index.

Update Management

Windows

To rollback to the previous update level, select Manage JET Updates in Excelsior JET Start Menu and click Undo.

Rollback does not remove the installed updates and associated profiles, so you can reapply MP2 later without installing it. Select Manage JET Updates and click Redo until it displays the current configuration as "jet-480-mp3".

Linux

  1. Run JET Setup to display the list of installed updates:
      jetsetup -show-updates
  2. Locate in the list the updates which you need to activate. Then run JET Setup again as follows:
      jetsetup -activate-update list

    where list is a colon-separated list of update names.

  3. Display the list of profiles available for the new combination of updates: jetsetup -show-profiles
  4. If necessary, create new profiles.
