OSGi Benefits

Deploying modules as OSGi bundles

Simplifies reuse between applications

Encourages (and enforces) modular design

Provides versioning

Enables dynamic module updates Dependency Injection framework

Provides efficiency for large SOA systems

Highlights of OSGi application Support in WAS Feature Pack

OSGi Release 4 Version 4.2 Blueprint component model for declarative

assembly, and simplified unit test

Extensions to the Blueprint component model for declarative transactions,

container-managed JPA, and resource reference configuration

Isolated enterprise applications composed of multiple, versioned bundles

with dynamic life cycle

Integrated bundle repository and ability to configure the location of externalrepositories to support application provisioning

Module sharing between applications

Module versioning within and between applications

Integrated administration of application bundles

Federation of lookup mechanisms between local JNDI and the OSGi

service registry

Support for deploying existing Web Application Archives (WARs) as OSGi

Web application bundles

JPA 2.0 Overview

Object-relational persistence is a key developer requirement for many

application developer scenarios. JPA is the Java EE standard for object-

relational persistence and was first introduced as part of Java EE 5. As part of

the Java EE 6 standards, JPA 2.0 (JSR-317) updates object-relational

capabilities with important developer APIs and enhancements.

Highlights of the JPA 2.0 implementation delivered in the feature pack include: Java EE 6, JPA 2.0 (Java Specification Request 317) specification compliant implementation

Important new JPA 2.0 standards-based features to help improve developer time to value

Achieve new levels of application performance with WebSphere Application Server V7

Query language (JPQL) extensions and improvements

Programmatic control of database access optimizations - fetch groups, fetch plans, and access intents

Enhanced integration with WebSphere eXtreme Scale in order to help improve data access

performance
