Although I guess that it would be possible to make all those calls manually,
I wonder what the advantage would be.
The RHS of a rule is already Java code and the LHS provides a lot of Java
functionality or can use eval() if neccessary.
Also you can embed the DRL in your source or dynamically create new rules
and add those using StringReader if need be: I'm currently working on a
business project where new rules are assembled by the application: POC works
like a charm.
If that is not feasible, I'd probably take a look at the
drools-decisiontables codebase which basically does a similar thing: replace
DRL/XML syntax with a new interface (decision tables).
Anyway, that's just my $0.02 ;)

Best regards
