EJB 3.0 and jMatter

EJB 3.0 and jMatter have nothing in common, except Java. We had two wonderful presentations today.

EJB 3.0 was presented by Rajan Ramanujan from Lincoln Financial. Here are some of the advantages of using EJB 3.0 over EJB 2.1:

  • Fewer Classes and Interfaces
  • Dependancy Injection ( Bean instance construction triggers injection of needed resources)
  • Simple Lookups
  • No required Container Interfaces
  • No required Deployment Descriptor
  • Simplified persistence
  • Object/Relational Data mapping
  • Designed to draw Developers to J2EE

jMatter is an Application Framework for constructing workgroup business applications based on the Naked Objects Architectural Patterns. The jMatter framework does the CRUD functions for you and provides a very rich drag and drop, calendaring, and reporting functions. Matt Payne made an application from scratch during his presentation; the application is all Swing and a Rich Client App. This rich app can be launched via java web start; there’s an example of Matt’s here; this example includes a groovy interpreter and the ability to import OVAL files via XMLBeans. Eitan’s slides about jMatter.org are available on the jMatter site; and Matt Payne’s slides are available at MattPayne.org/talks.

Spencer Reed Group, an IT Staffing company, sponsored this OJUG meeting by providing Pizza and Pop. They gave away 5 door prizes too.

1Staff, a premier IT training company, provided meeting room facility for the group today.
