        Key: HIVEMIND-67
    Summary: Add RemoteServiceImplementationFactory to support distributed systems
       Type: New Feature

     Status: Unassigned
   Priority: Minor

    Project: HiveMind
 Components: 
             framework

Description:
Till now HiveMind is an lightwight, single-JVM micro-kernel. But there are still some large, distributed systems. Is it a must to use EJB to develop these systems? I don't think so. If HiveMind developers can add a new service implementation factory, which will create a proxy of remote service on another box, we can throw away EJB forever.

The sample configuration may be something like:

<service-point id="local-service" ...  >
   <invoke-factory>
      <set-service property="..." service-id="local-proxy"/>
   </invoke-factory>
</service-point>

<service-point id="local-proxy" ... >
   <invoke-factory service-id="RemoteServiceImplementationFactory">
      <jndi-configuration configuration-id="..."/>
      <remote-service service-id="..."/>
   </invoke-factoy>
</service-point>

And this factory will create a proxy of remote service. The proxy will lookup the remote Registry( or maybe some other object) through JNDI, and pass the method call to it. The remote registry will call the real service and return the result.

The sample configuration for remote service on another box may be like:

<service-point id="..." expose-to-remote="true">
   <invoke-factory .../>
</service-point>
