The OSGi Enterprise Expert Group provided an update on their work. They have released an Enterprise Specification focusing on Java EE and component integration. Their next release will focus on bundle aggregation, dependency resolution, and enhancements to Blueprint and JMX. They are also working on support for Java service loading, cloud computing, and JCA integration.

Focus on
–
JEE integration, e.g. JPA, JNDI, Web Container
–
Component models, e.g Blueprint, DS
–
Remote Services
●
Adoption enabler driven by immediate needs
and use cases

4. What comes out next
●
Focus on concept of bundle aggregation and
isolation, aka applications, regions,
composites, …
●
Dependency resolution
●
Missing enhancements to Blueprint, e.g.
namespaces, interceptors, transactions, config
admin integration
●
JMX management update

5. What comes out next - OBR
OSGi Bundle Repository (OBR)
●
Long in the making, known as Felix OBR
●
Resolve dependencies based on new generic
requirements and capabilities introduced in R4.3 of
the core spec
●
Includes support for
–
Repository format, federated repositories
–
Resolver substitution
–
Resolution introspection

6. What comes out next - Subsystems
Subsystems
●
Provides aggregation of bundles and scoping with visibility boundaries and common
lifecycle
–
Can be bundled together in a single 'application' archive
–
Can be resolved based on a set of root bundles and their dependencies
●
Integrates with OBR
●
Uses new R4.3 Resolver Hooks from core spec
●
Scoping support
–
Application - Implicitly scoped subsystems
–
Composite - Explicitly scoped subsystems
–
Feature - Unscoped subsystem

8. What comes out next – JMX Update
JMX Update
●
Improvements from feedback on the existing JMX spec
–
To better suit certain JMX use-cases
• Like multiple frameworks in a single MBean Server

10. Cloud Computing
●
Open Working Group started after last year's
EclipseCon
●
Currently gathering requirements in RFP 133
–
Available publicly through osgi.org bugzilla (bug 114)
●
Themes
–
Provide information about 'current' cloud environment
–
Maybe standardized APIs for common Cloud functionality
●
