You can use multiple drl files in one KnowledgeBase using
KnowledgeBuilder.add. So, you can put your common functions in one drl
file and reuse it with each of your other drl files. This is true for
drools 4.x as well.

Package scoped means that the function can only be used within the same
rule package. The package may be split across multiple DRLs, but as long
as in the same package, all would be able to access the function. See
documentation for more info

Thanks Mark.
What do you mean by package scoped? In my scenario I have all
rules with
same package declaration but in various .DRL files. Is it
possible I create
common function in one file and use them in others? If yes,
please write
some code to explain it.
We do not want to use Java static method as we have 2 different
projects,
one for authoring the rules and another business application
will use the
rules. By creating faction in Java classes add dependencies for
the rules.
We will need to deploy Java classes with the rules.
