A very useful engine capability in Bonita Open Solution, is a recorder. This feature is in fact installed by default, but is may not be widely known.
A recorder listens to the different events taking place in the Bonita Execution Engine and records them all to a log.
The online BonitaSoft Documentation system now documents recorders. So, there are basically two steps to follow to configure and create a recorder. Click here to go straight to the tutorial which provides the code you will need to create a recorder and set it up.
Thanks to Philippe Ozil from the Services team for this tip, which was recently used extensively for a BOS installation.
Have fun with Bonita!
