I did a 15-minute presentation on OSGi and this tool, using the Counter Service Sample. See http://bit.ly/eclipsedemocamp and this blog entry for details and references.
I think the Counter Service Sample does a great job of showing OSGi and blueprint, with blueprint.xml files, with a minimum of code and overhead. Thanks!
A longer example that really shows JPA capabilities is "Developing OSGi Enterprise Applications" from the OSGi Community Event 2010 Conference.
It's the last event at the bottom. The assets are:
o Lab Instructions (pdf)
o Lab Assets (zip)
I used the info in the Lab Instructions to work with the sample and run it in eclipse.
Thanks for a good tool and samples.
