[rules-users] How to generate rule statements using MVEL 2.0 template?

[Michael Anstis]

You could take a look at drools-templates, and relevant sections in the
user guide, as a starter.

If that does not cover your requirements take a look at drools-templates
source code on github.

Alternatively have a look for MVEL templates on Google (other search
engines are available).

With kind regards,

Mike
