Enhydra: Enhydra, JOnAS EJB Server, and Jonathan ORB projects join forces

The Enhydra team announces a joint effort with Open Source advocates
BullSoft and France Telecom to deliver a complete, enterprise-class
application server. By combining BullSoft's JOnAS EJB server, France
Telecom's Jonathan ORB and Enhydra, these Open Source sponsors are
delivering a highly customizable Open Source application server that will
scale the entire range of Internet applications - from embedded handheld
devices to enterprise applications. The integration of an EJB engine in Enhydra
is the first step toward a full Java 2 Enterprise Edition (J2EE) platform.

This initiative identifies strategic areas of technical cooperation and builds
on the strengths of each contributing member.  In addition, the project will
leverage contributions and peer review by combining the large and rapidly
growing community of developers from all three projects .

As announced to the Enhydra mailing list, we are planning to offer full EJB
support in the Enhydra 3 release. This architecture will allow the business
layer of an Enhydra application to be written with EJBs, while servlets are
used for the presentation layer. To reach this goal, we are working closely
with the JOnAS team (BullSoft) to integrate the JOnAS EJB server and tools
into the Enhydra framework. JOnAS is a pure Java implementation of the EJB
specification that provides:

  • Support of stateless and stateful Session Beans
  • Support of Entity Beans with either Bean Managed Persistence or Container Managed Persistence
  • Support of all the transaction attributes
  • Support of JTA 1.0.1
  • Distribution using RMI and naming using JNDI

The current Enhydra application model will continue to be supported
and will benefit from the introduction of a robust EJB business layer.

The project has been kicked off with the creation of a branch to the Enhydra
source to integrate the JOnAS and Jonathan projects.  You can find further
information and the EJB project mail list at:

Further information about JOnAS and Jonathan is available at:

Planned for Q1, 2000, Enhydra version 3 will integrate the JOnAS EJB server
and Jonathan ORB.  A Beta release will be available soon from the EJB
Project page.
