Hello, I can run Java from within a scriptTask but do not seem to be able to use external classes properly. How might I call methods on a class using a serviceTask? A previous post[1] referred to creating an interface of the class and then referring to that interface. Is that interface the equivalent of an import in the native drools XML format? [1] http://www.mail-archive.com/rules-users@lists.jboss.org/msg15014.html Has anybody been able to get this to work? Can anyone point me in the right direction? Thanks!
