Not knowing the XML schema or the generated Java classes I can only outline the general principle.

if Request contains elist List<Enrollments>,  write a rule that matches the Request object and inserts:

rule "extractFromRequest"
when
   r : Request()
then
   for( Enrollments e: r.getElist() ){
      insert( e );
   }
end

If there is only one enrollment Enrollments within each request, it's just
   insert r.getEnrollments()

If you can conveniently write your rules against Enrollments objects, that's it. Otherwise, you might do the same, over again, at the Enrollments level.

(It'll become a problem if children of some element ought to be related to each other but this is only provided by them being children of the same parent. In this case, you won't be able to use the JAXB generated classes as WME classes.)

Thanks that makes sense.

How do i get to elements that are beans below Enrollments?  This doesnt seem
to work?

rule "EnrollmentsfromEnrollmentRequest"
when
   EnrollmentRequest( $es: enrollments )
   $e : Enrollments( enrollmentType ==  "NewEnrollment") from $es
then
               System.out.println("Found Subscriber
"+$e.EnrollmentPolicy.Person.getName()) ;
               System.out.println("for GroupID " + $e.GroupIdentifier.getGroupId()) ;
               System.out.println("Setting Source Name to Mike");
               $e.setSourceName("Mike") ;

end

org.drools.rule.InvalidRulePackage: Rule Compilation error : [Rule
