I use Jabaco from time to time. I'd love to make it my primary IDE. But Jabaco is dead. It's Manuels decision, but I really don't understand why he doesn't make it open source if he doesn't have the time to work on that project. So you'd better switch to b4j. Who knows when you can't use it any longer because of some Java restrictions (see JRE 8 problem her ein the forum)
A couple of weeks ago I searched the forum for help and I realized that there is a PHP Bug so that many forum entries are no longer readable. The problem still occurs. Check here:
Database sample App - SELECT / INSERT / UPDATE / DELETE
So, even no maintenance of the forum. So sad...
