[rules-users] functions

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
