[rabbitmq-discuss] rabbitmq - implement a proxy with RPC

[mysurf mail]

Hi,
All I want is the usage of an interface in the client . can the regular rpc
client supply me this>

and in another note :
I am experiencing problems in creating JsonRpcClient.
when debugging it - it stays on that line forever (doesnt move to the next
line of code)
when attaching the source I see it uses the primitive call of the RpcClient
when it asks
system.describe. I dont see it reaches to the server.
Should I supply something ?
here is my client code

JsonRpcClient client = null;
Connection conn = null;
Channel ch;
try {
       ConnectionFactory ConnFactory = new ConnectionFactory();
       ConnFactory.setHost(props.getProperty("Host"));
       ConnFactory.setPort(Integer.parseInt(props.getProperty("Port")));
       conn = ConnFactory.newConnection();
       ch = conn.createChannel();
       Channel channel = getServerChannel().getChannel();
       client = new JsonRpcClient(channel, "", "positions");
} catch (IOException e) {
    throw new RuntimeException(e);
} catch (JsonRpcException e) {
    throw new RuntimeException(e);
}
return (PositionServerServices)
client.createProxy(PositionServerServices.class);

And in the server i am doing
server = new JsonRpcServer(channel, "PositionsQueue",
PositionServerServices.class, positionServerInternalServices);

(and positionServerInternalServices is my implemntor of the interface. )
