The newest version of the JBoss Application Server comes with a patching utility that allows you to automatically update parts of the server with newer versions. Currently, the patching is done using a CLI. Any patch can be reverted, and the administrator is able to track the history of patches.
A patch can be applied by simply calling the patch apply <file path> (without -) command. A complementary command is patch rollback --patch-id = id, a patch-rollback command. To obtain information about the installed patches, simply call patch info. Patches are distributed by teams responsible for specific WildFly subsystems. Visit their websites if you need a patch for a specific module.
