[Springframework-developer] BeanFactory partial pre-population with application objects.

[Venkat S. <vso...@ho...>]

Hi,

The subject may sound strange but please bear with me. I am trying to use 
Spring to isolate ICE (http://www.zeroc.com) specific depedencies. I could 
prototype the client side interaction (Thanks to Jurgen for pointing me in 
the right direction), but have come to a block when trying Server side.

ICE has a kind of app server called IceBox, it loads different services from 
a Config file, it has a feature called UseSharedCommunicator, which means 
all the loaded services share the same ICE runtime instance and calls to 
other services located in the same instance are treated as local calls.

Basically you wrap a ServiceImpl class in ServiceAdapter so that IceBox can 
load it, here is an example of the ServiceAdapter for a ServiceImpl class 
PrinterI

public class IceBoxService  extends Ice.LocalObjectImpl implements 
IceBox.Service {

        private Ice.ObjectAdapter adapter;

        public void start(String s, Communicator communicator, String[] 
strings) {

            this.adapter = communicator.createObjectAdapter(s);
            Ice.Object object = new PrinterI(communicator);
            adapter.add(object, 
Ice.Util.stringToIdentity("SimpleFCASearch"));
            adapter.activate();
        }

        public void stop() {
            adapter.deactivate();
        }
    }

}

I was planning on writing a generic IceBoxService which takes a parameter to 
context.xml file and instantiate a BeanFactory which loads the ServiceImpls 
and resolve the services they depend upon.  But, if you observe how the 
PrinterI is instantiated, the communicator instance passed to it should be 
one that is supplied by the IceBox server (passed in as a parameter to start 
method). How to make a bean factory aware of this communicator?

The following code explains the behaviour I am looking for:
BeanFactory bf = new ClassPathXmlApplicationContext();
bf.setBean("communicator", communicator); // Setting/passing the application 
communicator instance to the Bean
bf.load("context.xml"); // refers to the communicator bean passed in above 
statement.

Thanks for your time and patience.
