What should we talk about?
Using Eclipse with the Dali Persistence Tools, lets look at techniques to:

1. develop enterprise-grade applications that are either:

a. built from the bottom-up with a pre-existing database
b. built from the top-down starting with business domain entities requiring persistence
storage (e.g. Derby, MySQL, and DB2, Google Big Data)

2. incorporate a JPA approach into your existing JEE architecture

3. minimize data-impedance mismatch issues

Development Environment (1 of 2)
IDE Version
3.6 – Helios
Eclipse
3.7 SR 2 – Indigo
IBM Rational Application Developer 8.0.4 (based upon Eclipse 3.6.x)
• For Eclipse environment use the “Eclipse IDE for Java EE Developers”
bundle.

• This bundle contains the Web Tools Project which inclused the Dali JPA project
and the EJB tools project among others

Note: Used JDK or JRE 1.7 for projects and server environments (unless provided by the IDE or
Application Server)

Development Environment (2 of 2)
Plugins / Features Version
Google Plugin For Eclipse 2.5.2 (for Eclipse 3.7)
Oracle Glassfish Server Tools 2.0.0 – Download from “New Server” wizard
JBossAS Tools 2.3.0 – Download from “New Server” wizard

JEE Deployment Topologies
Derby MySQL DB2
GlassFish Server Open Source Edition Y Y Y
WebSphere Application Server (1) Y Y Y
Google App Engine N/A N/A N/A
JBoss Y Y Y
* (1) Used IBM Rational development environment – Rational Application Developer
to exploit OOTB server tooling add-ons and other productivity conveniences for
WebSphere Application Server v8 test/deployment

Application Servers
Application Server Version
GlassFish Server Open Source Edition (See Note 1) 3.1.2 (JEE6)
WebSphere Application Server 8.0.0.2
JBoss (See Note 2) 7.1

Note 1:

• Made use of EclipseLink 2.3.2 (for Indigo) JPA Platform / User Library implementation
donated by Oracle (TopLink)

Note 2:

• Makes use of Hibernate JPA implementation
