hi Simon - Here's the full trace.
Thanks.
Isn't there a "caused by" trace following this trace? From looking at the
Tuscany runtime code in JavaBeansDataBinding, I would expect to see this.

I am getting the following error when executing a query in

All composites load fine in webapp and I also tried out a few
empty get / sets with strings.
However on db access and in returning an ArrayList of Person.
Person is the interface to concrete class PatientImpl. I am
passing ArrayList of Person.
I put PatientImpl objects in ArrayList of Person.
