## Post #1 by @system

Dear all,

Please warmly welcome three new committers to the ref_impl_java project: Bert Verhees, Erik Sundvall and Mattias Forss. They all have been very much involved in the Java project and have contributed to the ref_impl_java project in many ways.

Bert will be working with the persistence layer based on OR mapping (Hibernate 3). Mattias will be responsible for the adl-serializer and xml-serializer components, which are used by the Archetype Editor. Erik will lead the experiment on the immutable-rm-objects. Their further engagement will undoubtedly speed up the implementation work and create more synergies between different development groups.

Welcome again!! :))

Cheers,
Rong
