Re: [ecf-dev] Sending crendentials with every request

[Scott Lewis <slewis@xxxxxxxxxxxxx>]

Hi Peter,

Not completely sure I understand what you are wanting to do, but you 
could look at overriding these methods:


1.  On service consumer/proxy, all rpc calls go through: 
org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.sendCallRequest(RemoteServiceRegistrationImpl, 
IRemoteCall)

to asynchronously send message for remote invoke.  As part of this impl 
of this, the following method is called:

sendSharedObjectMsgTo(remoteRegistration.getContainerID(), 
SharedObjectMsg.createMsg(CALL_REQUEST, request));

Note the CALL_REQUEST is a String == "handleCallRequest"

2.  On service impl/host side there is this method which gets called 
when CALL_REQUEST is received:

org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.handleCallRequest(Request)

This ends up executing the request, and calling this method to send 
response back:

org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.sendCallResponse(ID, 
Response)

which calls this method to construct and send message:

                    sendSharedObjectMsgTo(responseTarget, 
SharedObjectMsg.createMsg(CALL_RESPONSE, new 
Response(response.getRequestId(), getSerializableException(e))));

Note the CALL_RESPONSE is String == "handleCallResponse"

3. On service consumer/proxy this method is then called:

org.eclipse.ecf.provider.remoteservice.generic.RegistrySharedObject.handleCallResponse(Response)

If you want to add to what's sent in every rpc, you could add to the 1 
(what client sends) and to 2 (what server received and how processes it) 
by adding your meta-data to the Request instance that's sent (has to be 
Serializable of course).

Does that help?

Thanks,

Scott
