[rules-users] RES: Problem with proxy objects

I think you didn't understand my problem.
I don't have any problem related to Java arrays. 
My problem is drools is not working with proxy objects. 

I am executing drools rules with one javassist object
(package.MyClass_$$_javassist_2) and drools is not recognizing this object
as package.MyClass and is not executing my rule.

Thanks,

Rogério

<quote from="Drools Expert Manual">
Unfortunately a Java array does not implement the Iterable  interface, so we
have to use the JDK converter method Arrays.asList(...).
</quote>

Try
  ksession.execute( Arrays.asList( new Object[] { myObject} ) );
