@Davide, there is *nothing* in Drools that is a full-fledged replacement for eitherr #define LIMIT 100 as in C, or const magic = 4711; as in Pascal, or..., or... Any modern programming language has this facility, and templates are no replacement, and globals still need Java code for their initialization prior to the insertion of any facts. @Richard Using some sort of parameter fact is another workaround, although this requires an additional CE in rules requiring such a "constant". Also, a simple Java class containing just global final statics could alse easily (Java-)compiled and deployed with DRL packages importing these constants. (Besides, many constants are related to Java classes and that's where they ought to be declared anyway.) -W On 27/02/2012, Davide Sottara <dsotty(a)gmail.com&gt; wrote:
