PicoContainer Support
XFire is very component oriented and you wont have problem to use its components into Pico, anyway few special components are needed in order to have a clear and easy integration with Pico and XFire comes from factory with it.
Those components are:
PicoObjectServiceFactory
PicoObjectServiceFactory is a PicoContainer specialization for Java objects-specific implementation of theServiceFactory interface which uses a given picocontainer to pick service objects instance when it's about to invoke them.
Some of the constructors gets an ObjectReference, which is very useful when you use NanoWar for instance.
