Springsource is alive because they are creative and innovative. If OSGI really can bring us what Mr. Rod Johnson is promising, then it can become another de facto like spring itself. They are trying to attack jar, war and ear files. Rod Johnson says that Jar is created when Bill Clinton and Monica Lowinsky's affair revealed and It must become history now. Productivity will prove the reality. Terracotta team enhanced JBoss cache with their tool and made it 12 times faster. Do you think JBoss cache will stand still? Of course not.
I am happy that nowadays startups dare to go beyond standards to become a de facto. I am not fenatic about a special kind of technology as they all have great impact upon eachother (like EJB2 and spring and spring and EJB 3). Efforts never become standards unless they bring us productivity.
