Hi, Jim.
Your changes seem to be causing some regressions. I got the following
exception in a web srevice sample now.

I checked some changes in to support system services scoped to acomposite hierarchy in the Java SCA runtime. This will allow us to addsupport for things such as type systems specific to an
application andprogramming model extensions such as OpenJPA and Hibernate.>> As part of this, the SystemCompositeComponent and AutowireComponentspecializations have been removed, leaving
CompositeComponentImpl as thecomposite implementation that forms both the application and system runtimetrees. Previously, each composite contained one set of children. This hasbeen changed so
that each composite will contain a collection ofapplication and system children in separate namespaces. Each composite onthe "application" side of the runtime composite hierarchy may
contain bothapplication and system children. For example, normal user-providedapplication artifacts and system services such as a type registry or EJB3entity manager factory. Composites on the
"system" side of the runtimewill only contain system artifacts as children and will not have anyapplication children (the collections will be empty).>> The application and system
sides of the CompositeComponentImpl aredistinct. Fro example, autowiring on the system side will traverse up thesystem side of the runtime hierarchy while application components may notautowire to
system targets. Since system and application children arekept separate to avoid collisions, additional APIs have been added toCompositeComponent for navigating the hierarchy (e.g.
getSystemChild).>> Also, in line with these changes, I removed AutowireComponent and movedthe methods up to CompositeComponent. In addition to removing casts, thiswill allow us to add support
for autowiring application components, whichwill hopefully be included in the SCA specs soon.>> Finally, I moved SystemAtomicComponent to SPI so that people can createcustom system
extensions. This will allow us to add support for OpenJPA andHibernate where an EntityManagerFactory and SessionFactory respectively aremanaged by a custom system atomic component contained in an
applicationcomposite. An injector can be used to access that system component andinject a JPA EntityManager or Hibernate Session onto a component instance.Similarly, a type system helper could be
stored in a system component foruse by an application.>> Jim>> ---------------------------------------------------------------------> To unsubscribe, e-mail: [EMAIL PROTECTED]> For
