CjOS Project Revisited

The CjOS Project is a research project for a Java-based operating system with a combination of C/C++ and Java. The project has an emphasis on the Java-side of a Java-based operating system. The project has an emphasis on desktop, laptop and server machines. The project has emphasis on long-term stability of both API and implementation we like to call perfect backward compatibility.

Recent activity
One of the most active parts of the project right now is the investigation of OSGi. We're building OSGi modules from a large, monolithic Java class library.

Release 1.0
In addition, the first release of the OSGi initiative is now available. It brings many of the production-quality APIs from the CjOS Project to OSGi-compatible applications, such as the Eclipse platform and IBM WebSphere Application Server.

Allow me to provide just one example of what you can do now. The Smart Archive feature enables your Java application to read a file inside an archive inside an archive inside an archive--without the use of temporary files. It also enables you to find files inside an archive inside an archive inside an archive--without the use of temporary files.

The CjOS Project maintains a collection of Java archives. Traditionally, these Java archives are delivered to the Linux platform as a corresponding collection of RPMs. By adding the CjOS Project archives, you enable your Java application to benefit from a large, stable, backward-compatible, monolithic class library of working Java code.

Modular initiative
The previous collection of Java archives do not map directly to a collection of OSGi modules. Using the power of the XVCL Processor, we're re-generating existing Java source code into OSGi modules.

By moving to OSGi, we have discovered and fixed hidden problems in our design and implementation. So, the OSGi initiative has improved the overall quality of the project.

Check it out
Download the recent release and experiment with it inside of your OSGi application.

Thanks for listening,
