Hi David,
We decided to defer OSGi to the next release (which will occur when
OSGi support is ready). We were not happy with the degree of testing.
For now you need to check out the Jersey trunk
svn checkout
https://jersey.dev.java.net/svn/jersey/trunk/jersey
jersey --username username
and do:
cd osgi
mvn clean install
and then use those built OSGi specific maven artifacts.
Jakub can provide further details, especally w.r.t. your code.
Paul.
