Simple Example - student

The "student" example is intended to provide a simple example of using JPA-RS with a single entity persistence unit in a web application.

Environment

The following are the minimal requirements for this example.

Overview

The following steps will be performed in setting up and running this example in your own environment

  1. Installation & Configuration
    • Check out student example from GIT
    • Database connectivity
    • GlassFish - Datasource configuration
    • Verify config
    • Deploy web application
  2. Running the Example
    • View metadata
    • Create entity
    • Update entity
    • Query entity
    • Delete entity

Installation and Configuration

1. Clone "examples" from git. The "student" example is stored under student folder.

   git clone git://git.eclipse.org/gitroot/eclipselink/examples.git

2. Configure datasource. Create an XA Datasource connection pool called "JPARSStudentDS" and define a new JDBC Resource using this connection pool. You can use any of the databases supported by the eclipselink.
