Edson,

Thanks…and I am considering that option as well…but the nice thing about the functions in the drl file is the system remains much more fluid..in other words, if I can focus on doing what I want to do all within the DRL file, it proves the flexibility of the system more to me than having to have developer recompile the application itself with new classes. Does that make sense?   Also, I would just like to know that I can actually make functions work for future reference.

Thanks,

Chris

   Chris,

   If you are creating a function library, why don't you create it as static methods in a java class? easier to develop, to unit test and you can use "import function" in the DRL to import all of them.

Ok…I am trying to build a function library in my .drl file and I added this one test function

function String outputString(String sData){

    return sData;

}

And no matter where I place this in my .drl file, I get an exception one way or the other with compiling when I try instaniate and fire my rules. The .drl file works exactly as expected if I remove this function declaration, and when I *do* try to add it, I do not actually call it anywhere…but get those errors.

So my question is, where exactly do I need to place function declarations..

Thanks,

Chris
