Excelsior JET 4.8 US-DST Changes Hotfix

Daylight Savings Time (DST) rules used in Excelsior JET Runtime need to be changed accordingly to the US-DST changes for 2007 impacting North American residents and customers. To make changes in JET Runtime you need to install this hotfix.

Note: Requires Maintenance Pack 2

WARNING: Hotfixes address particular problems reported by Excelsior JET users and discovered by Excelsior test engineers between product and Maintenance Pack releases. They are only tested against the core test suite used during development and on the customer scenario(s), if any. We therefore only recommend you to install hotfixes in the following cases:

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

Download Instructions

If you are a registered customer of Excelsior JET 4.8, but have not received a user/password combination for Hotfix download, request it from our Support Dept. at support@excelsior-usa.com.

Depending on the platform and Excelsior JET Edition you are using, click one of the download links below:

Installation Instructions

This hotfix installs on top of the Excelsior JET 4.8 and Maintenance Pack 2. If you need to make a fresh installation, install Excelsior JET 4.8 first, cancel JET Setup, apply Maintenance Pack 2 and only then apply this hotfix.

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

Profile Management

Installation of this hotfix 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 this hotfix. 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 Locate in the list the outdated profile(s) that you need to refresh and write down their numeric indexes.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 thid hotfix later without installing it. Select Manage JET Updates and click Redo until it displays the current configuration as "jet-480-hotfix24".

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.
