If you have defined functions in a drl, in order to use those functions in another drl of a different package, you will have to import each individual function, like package A; function void func1 () { System.out.println("Hello"); } function void func2 () { System.out.println("There"); } pacakge B; import function A.func1.func1; import function A.func2.func2; rule Test when then func1(); func2(); end Is there any way to do something like import function A.*; in Drools 5.5.0 to use all the functions defined in another drl?

So in 6.0, we are not even able to use drl functions from another drl? I sort of require that because I will have rules that are added to the kbase in runtime with updated functions. Then what about this? If I create a java class with all the static functions wrapped in jar (instead of defining them in drl), would that be possible to dynamically load the jar into the current kbase first and then let those rules added in runtime to use functions from that jar by simply adding import function mydynamicjar.MyFunc.*; ? A simple code snippet on how to achieve that would be nice, thanks a lot! -- View this message in context: http://drools.46999.n3.nabble.com/Importing-functionS-from-another-drl-in...
