Stopping short of open sourcing the language itself, which I think is a good thing, Sun are today expected to announce that they will be open sourcing many of it’s development tools and applications.
- a Java EE 5 Application Server (based on GlassFish? – this would seem logical since GlassFish is already open source)
- Sun Java System Portal 7 – an integration server
- Java Studio Enterprise (their enterprise flavor of their IDE, based on NetBeans)
- message queing software
- Web Services Interoperability Technology
