This document shows how to apply patches to the JOC Cockpit.
Applying one or more patches to the JOC Cockpit
Applying patches automatically
To apply one or more patches to the JOC Cockpit you have to:
- copy all patches you want to apply to the patches folder of the JOC Cockpit installation.
- do not remove already installed patches to avoid overwriting an already applied patch with an older version
- Double click the
patches\binfolder of your JOC Cockpit installation.
Applying patches from the Command Line
To apply the patches
java -jar patch-executor-<VERSION>.jar
To see the patch usage page with the general usage information.
java -jar patch-executor-<VERSION>.jar --help
Parameters to see the usage page are:
?, -h, --help
Rolling back an already patched version
To rollback already applied patches you have to delete all the patch files from the patches folder of your JOC Cockpit installation.
Rollback from the command line
To roll back already applied patches from the command line type:
java -jar patch-executor-<VERSION>.jar --rollback
Delete all patch files from the patches folder and then type:
java -jar patch-executor-<VERSION>.jarwithout any further parameters
Difference between processing rollbacks automatically and from the command line
If you want to rollback automatically then you will first have to remove all the existing patch files from the
When the patch executor then recognizes that there are no patch files in the patches folder an automatically rollback is performed.
In contrast, when you type
java -jar patch-executor-<VERSION>.jar --rollback in the command line, a rollback will be performed, no matter which patch files reside in the
When you run the patch executor it will check if a copy of the (original)
joc.war file has already archived in the archive folder of the JOC Cockpit installation. If not, a copy of the original
joc.war file will be copied to the archive folder.
If a copy of the
joc.war file already exists in the archive folder, it will not be overwritten. This ensures that only the original
joc.war file is archived and not an already patched one. It also ensures that the patch executor is able to perform a rollback to the original state.
When a new installation is performed on an existing JOC Cockpit Installation the Setup will clean up the patches- and the archive folder of the previous installation.
