Hi David,
As an aside there is OSGi support in Jersey, some brief documentation
here (which needs to be expanded a bit):
https://jersey.dev.java.net/nonav/documentation/1.4-SNAPSHOT/user-guide.html
#osgi
But if i understand correctly what you want to do is plug in an IoC
framework, iPOJO, into Jersey correct?
I do not know of any pre-existing work using iPOJO, and this is the
first time i have heard of iPOJO, so it is tricky for me to guide you
with specifics of your case.
We do not have strong documentation around this area, so the best
place to look is code and JavaDoc of the components and existing code.
I think the best thing to do in this respect is look at the Guice
integration code:
https://fisheye4.atlassian.com/browse/jersey
http://download.java.net/maven/2/com/sun/jersey/contribs/jersey-guice/1.4-SNAPSHOT/jersey-guice-1.4-SNAPSHOT-sources.jar
https://jersey.dev.java.net/nonav/apidocs/latest/contribs/jersey-guice/com/sun/jersey/guice/spi/container/servlet/package-summary.html
Specifically look at the GuiceComponentProviderFactory:
https://fisheye4.atlassian.com/browse/jersey/trunk/jersey/contribs/jersey-guice/src/main/java/com/sun/jersey/guice/spi/container/GuiceComponentProviderFactory.java?r=HEAD
Notice that it implements IoCComponentProviderFactory which is
responsible for returning IoCComponentProvider instances based on the
class (returning null means it cannot support the class as a
component). There are a few extensions of IoCComponentProvider that
signal to Jersey the type of life-cycle and injection control.
For example, with the Guice integration it supports three types of
control:
1) Guice instantiated and Jersey managed with
GuiceInstantiatedComponentProvider implementing
IoCInstantiatedComponentProvider;
2) Jersey instantiated, Jersey managed and Guice injected with
GuiceInjectedComponentProvider implementing
IoCProxiedComponentProvider; and
3) Guice instantiated, Guice managed and Jersey injected with
GuiceManagedComponentProvider implementing IoCManagedComponentProvider.
I don't know enough about iPOJO to say if an of the above fits your
requirements.
Hth,
Paul.
