Course Outline

Goal: Educate EclipseLink users on advanced usage of EclipseLink JPA

Outline

• 1 - Course Introduction

• 2 - Configuration
  • JPA: persistence.xml, annotations, and orm.xml
  • EclipseLink JPA: PU Properties, annotations, eclipselink-orm.xml, and query hints
  • EclipseLink native ORM: sessions.xml and deployment.xml
  • DatabasePlatform
  • Server Platform

• 3 - Mapping
  • Additional Mapping Types
  • Private Owned

• 4 - Entity Weaving
  • Weaving features: Lazy Loading, Fetch Groups, Change Tracking, State Caching
  • Dynamic and Static usage

• 5 - Querying
  • Dynamic Querying using Expressions (native criteria)

• 6 - Transactions
  • Additional Locking options

• 7 - Caching
  • Isolated Cache Usage
  • Shared Cache Config
    • Cache Types: FULL, WEAK, SOFT_WEAK, HARD_WEAK, NONE
    • Invalidation/Expiration
    • Cache Coordination

• 8 - Diagnostics
  • Logging
  • Profiling
  • JMX/MBeans

• 9 - Customizations
  • Descriptor Policies: Instantiation, CloneCopy, ...
  • JPA Entity events and Descriptor Events
  • Session Events

• 10 - Performance Tuning
  • Graph Loading with minimal SQL
    • FETCH JOIN
    • Joining and Batching Query Hints
  • Projections versus Entity Queries
  • Leveraging the cache
    • Pre-loading
    • Cache Effectiveness

Additional Topics

Depending on the application architecture being used there are a variety of additional topics which may be covered.

• EclipseLink JPA in a multi-tiered architecture
• EclipseLink JPA in a rich client application (JavaSE)
• EclipseLink JPA in an OSGi container

Exercises

Requirements:

• An IDE - the projects provided are for the Eclipse IDE but the exercises should be easily adjustable to any development environment
• A Java EE 5 or better Container - A web container should also be usable but may not support dynamic entity weaving
• EclipseLink
• Exercises - initial projects and instructions

Downloads

The courseware will be developed as part of the EclipseLink project in trunk @ /svnroot/rt/org.eclipse.persistence/branches/1.2/documentation/courseware/jpa/blackbelt
