Jini Service as local object reference

Hi there,

I'm trying to develop a service which can be configured to run as Jini service or to run as local object, when used by a client application.

The reason is that I want to remove the RMI overhead of a method call when, in a specific environment, I know that I'll always use the service locally.

 

To be more specific: 

I launch an environment by launching several services. For instance: ClientService and ServerService (ClientService acting as client of ServerService).

On an environment type A: I launch a ClientService on host1 and ServerService on host2 (Both Jini services)

On an environment type B: I launch a ClientService and ServerService on host1 (Both Jini services)

What I want to do is to improve performance for type B environments, by configuring ServerService to run as a "local service", and thus eliminate the RMI overhead of ClientService to ServerService method calls and ServerService event invocations to ClientService.

 

When ServerService run as Jini, I'm creating a pure RMI proxy for the implementation:

 

serviceImplementation = new ServerServiceImpl(this);

proxy = (IService) exporter.export(serviceImplementation);

 

... where exporter is configured like this:

 

/* Exporter for the server proxy */

    exporter = new BasicJeriExporter(TcpServerEndpoint.getInstance(0),

                                     new BasicILFactory());

 

 

What should I do to have ClientService to use ServerService as if it were a local object reference?

At a first glance you could say that to accomplish what I want, I would simply have to make ServerService proxy = serviceImplementation:

 

serviceImplementation = new ServerServiceImpl(this);

proxy = (IService) serviceImplementation;

 

 

That was what I thought too. The problem is that my serviceImplementation is not Serializable!!!

 

Does anyone know how can I overcome this problem?

Should I implement a LocalProxy which implements Serializable? But how can it reference the serviceImplementation when serviceImplementation is not serializable?

 

Thanx for the help.
