Comic Example using RCP

Software Required

This example illustrates the use of EclipseLink JPA in a simple RCP application. Running this example requires OSGi (Equinox) as well as the following bundles.

  • EclipseLink OSGi bundles (available from the EclipseLink Downloads page and P2 (see Installing EclipseLink OSGi in PDE).
    • org.eclipse.persistence.core - Core EclipseLink Bundle
    • org.eclipse.persistence.asm - EclipseLink bundling of ASM to enable byte-code weaving
    • org.eclipse.persistence.antlr - EclipseLink bundling of ANTLR used for JPQL parsing
    • javax.persistence - Java Persistence API 2.0 specification
    • org.eclipse.persistence.jpa - EclipseLink JPA Bundle
    • org.eclipse.persistence.jpa.osgi - EclipseLink JPA OSGi Bundle (required only with EclipseLink 2.1 and above)
  • Derby JDBC Driver (available from EclipseLink examples SVN)
    • org.eclipse.persistence.derby - Provides access to the Derby client driver, but does not contain it. See the ReadMe.txt for configuration instructions.
  • Example Bundles (available from EclipseLink examples SVN)
    • org.eclipse.persistence.example.jpa.comics.model.annotated
    • org.eclipse.persistence.example.jpa.comics.setup
    • org.eclipse.persistence.example.jpa.rcp.comics

Understanding the Example

The example is composed of 3 bundles

org.eclipse.persistence.example.jpa.comics.model.annotated Bundle

This bundle contains the domain classes with their JPA mappings specified through annotations. The only required bundle is javax.persistence version "1.99". This is an OSGi-aware version of javax.persistence.
