Using Java Beans with Tuscany
Dear Simon,
First of all, my latter problem (regarding "No service invoker is available
for reference default" error) was saved. I think dependencies wasn't
causing this problem. Certainly, I use another dependencies, but I had
followed your steps and it was right. I think the problem was with the
composite file: the component name it was wrong. Thank you very much.
Now, it seems I have a problem with the JavaBeans, I think:

The cause of the error seems to be:
Caused by: java.io.NotSerializableException:
eu.services.information.repository.Repository
Looking at the Repository implementation it isn't marked as serializable so
Tuscany can't use pass it by value. You either need to make this type
serializable or construct an InformationObject implementation that doesn't
include the Repository.
