Hi William, jBPM's license is LGPL. This means roughly that you can freely use it in your own products and distrubute the result without any problem. However, if you intend to modify jBPM or extend it by modifying the sources, then your modifications should be given back to the jBPM community, i.e. the modified jBPM (or even the resulting product if this would be the modification) should carry the same license as jBPM (LGPL).
