1.6. Are we starting from scratch?

If you’re going to develop to the OSGi platform, does it mean that you need to drop your existing development platforms, such as JEE, and learn a new technology from scratch yet again? Or, even more important, can you leverage code from any of your existing enterprise applications?

Fortunately, the OSGi platform builds heavily upon JEE. As you’ll see, there’ll be several cases where we use, in some form or other, existing specifications defined by JEE, just in a slightly more modularized and isolated manner. This means that you’re able to use the skill sets you learned in the past.
