Enterprise Java CORBA Component Model

EJCCM is an open source Java implementation of the Object Management Group's CORBA Component Model. EJCCM has been developed by the software engineering research team of CPI and provides a platform to:

Define components (attributes and ports) and component homes
Specify component characteristics and properties (CORBA Software Descriptor, CORBA Component Descriptor, and Component Property Files)
Define component assemblies (Component Assembly Descriptor)
Deploy component packages (JAR files) on remote hosts
Automatically create, configure, and connect distributed components

What is the status of the EJCCM?

The current version of EJCCM is an alpha release still under development and is not fully compliant with the formal CCM specification. The EJCCM alpha release has been tested but not all implemented features have been fully tested. Users are welcome to assist with testing and can report bugs by creating an account with the EJCCM Bug Tracker.

Current Status of EJCCM:

Compiler for OMG IDL3 specifications that supports most of the OMG IDL 2.x and 3.0 keywords.
Code generator that generates IDL 2.x from IDL 3.0.
Code generator for component skeletons as defined in the language mapping.
CIDL compiler that supports basic container-managed persistence.
Functional HomeFinder.
Functional multi-threaded component Container that supports service, session, process, and entity component types including persistence and event management.
Descriptor-driven deployment including AssemblyFactory, Assembly, ServerActivator, ComponentServer, ComponentInstallation, HomeFinder, and a simple deployment tool.
Support of many uses cases associated with deployment descriptors.

When does EJCCM change?

Since EJCCM is an open source project we rely on our own resources as well as input from the user community to make improvements. We accept bug inputs and feature requests. As we have the resources, we fix bugs and add features. (Or if the community has resources…)

The EJCCM TODO list includes:

Graphical component builder and code generator.
Graphical packaging and deployment tool.
Support for Security Service.

Certainly when major compliance or functionality bugs come up, we try to fix them and release as soon as possible. We have incentive to do so since we not only developed EJCCM but also use it as the framework for several of our projects. See BEST, AISRP

How do I obtain the EJCCM?

All the EJCCM tools (i.e. compilers, code generators, and runtime) are written in Java and require a Java runtime and a Java CORBA 2.4+ compliant product to use them. The EJCCM distribution can be downloaded on the Download Page. Users are encouraged to join the Mailing List for FREE technical support.

Currently supported configurations.
