[rules-users] Dynamically create rules in java

[Edson Tirelli]

    Brian,

    Look for the XXXDescr classes (e.g. RuleDescr, PatternDescr, etc) in
drools-compiler. If you populate this classes directly, you avoid the steps
of generating the DRL string and parsing them back into the descriptor
classes.
    The best you can do to get one example is create a simple program with
the rule template you want, use the parser to parse it and inspect the
result to know what is expected.
