[rules-users] drools dynamic LHS

[Leonardo Gomes]

The Context fact I mentioned would be populated with values coming from a DB
or properties file. At runtime you can read the right properties file,
create a "Context" object and feed the working memory with it plus all the
other regular facts you already have. With this you achieve the
parametrization you're looking for, and there's no need to change code for
that.

Another approach is the one described by Ansgar with different DRLs. Both
would work, you just need to make up your mind :)
