Tohu version 1.6.1 works with Drools 6.0.1 and it may work with later versions.

Which particular version of Drools do you want to use?  Have you tried using Tohu with this and found something that doesn't work as expected?

I haven't used either since last year but if you've encountered a specific problem then let me know and I'll attempt to fix it and release a new version of Tohu.
