Does Debian do Enterprise Java Beans (EJB)?
There is activity in this area, the most noteworthy being the Open Source EJB implementation from Bull in France called Jonas. I have done some work with this system and it provides a good start towards a full EJB feature set. In particular, it provides a transaction monitor and a container based persistance implementation. I have used this system on Linux with free databases such as Postgresql. I have not been able to get the system fully operational on Kaffe. Additionally, the system depends on many Sun APIs which have not been cloned (JTA, JNDI, and EJB itself).
