Description

In Drools 2.1 I had some .drl files with <java:functions></java:functions> in them. These functions were working fine. When I switched to 2.5 I now get errors stating that those functions cannot be found. I saw an old bug from 2.0 relating to the serialization of rules losing functions. Is this bug back.

Note: I am using the JNDI to point to the rulebases which does serialize them.

I've seen a couple postings for 2.5 where these needed to be static; might want to check if that's the problem.

yes need to be static, and should be serializable if you are loading the rule base the normal way.

Most app servers do serialize the first time you bind to JNDI.

The functions are marked public static. I am not sure what you mean by the function must be serializable.

Can you do a integration test that tries the rulebase without serializing it? (ie just directly invokes it)?
