Is this the default behavior in Drools 2.5+? I.e. compile the rules to a jar file containing .class-files followed by the loading of this jar? (I can see on the JavaPolis 2005 presentation a source ddj is also generated) And I suppose the rules do not have to be recompiled the next time you use them, but does it automatically detect changes to the rules when deciding whether it has to recompile (or not)? Or do you have to ensure the compiled version is the latest one yourself? Can it handle changes to rules dynamically? I have to agree with you, it does not seem to be well documented yet :-)
Could you shed a small light on how Drools compiles/interprets rules and handles changes to the source files? I'm mainly talking about the Java semantic module here. A broad overview would be much appreciated. If there is some documentation I haven't found yet on this topic (without the need for me to go browsing the entire Drools source code), some pointers would of course suffice.
