[rules-users] Some question about Drools

Hi everyone, I have been working out with Drools, and a few more doubts have appeared. In Guvnor, each rule is defined inside a package. When you create a new rule you must define the package where it belongs. Guvnor doesn't create any kbase, you can see a package (in Guvnor) like a DRL file split in different parts: the imports, the globals, each rule, etc. So Guvnor is only in charge of maintain different versions of that DRLs. 1) Can this be done dynamically? I meant, will the workflow change as soon as I save the new rules on any pre-existing package? If I declare the entities in Guvnor, this will use the "declare" keyword to define a New Data Type. Now... 2) Would this allow me to add workflow steps and rules as well as general data entities? and, the last one 3) What should I have in me interface to be able to use Drools as me rules engine? I don't get it yet... And if you can recomend me any web site with information about all this things it'll be nice. Thanks Carlos S. Moreno
