Hi Jim / Jeremy / Axis2 & Celtix binding folks
Continuing with the simple RMI Binding that I am working on... here
are the
things that I have done to move it forward in steps... (from a null
inbound
wire to being able to host the RMI Service. Now I am on the path to
invoking the service). Here is what I have done in the
RMIBindingBuilder.build method: -
- created the inbound and outbound wires
- set up anInbound and Outbound Invocations chain for these wires
resp.
- set up a Java target invoker on the InboundWire (did not
understand this
as I expected that this should be set onto the outbound wire)
You should only need to create the target invoker for the reference
and not the service side (the target invoker is responsible for
dispatching on a service). The invoker itself is cached on the target
side and sent down the invocation chain with the message, pulled off
by the final interceptor and invoked. This process is described in
the slides under /doc. The reason for this is so target invokers can
be optimized to avoid resolution on every invoke when the source of a
wire is of the same or lesser scope than the target (e.g. request--
>request; request-->module).
- Now I am stuck with Interceptors... it seems like the outbound
wire need
to be configured with interceptor. This seems to be little tricky
as I must
create MessageChannels and so on... any suggestions on how I could
do this?
Yes it's very tricky, particularly with callbacks ;-) The connector
handles this so the extension developer should not need to worry.
Axis2 and Celtix folks, how have you guys done this? If this is
not the
way to do this, what else is?
If you give me until tomorrow, I'll check a sample binding in of how
to do this. I also have some related changes I want to discuss
pertaining to the Wire Service and how wires are produced so I'll
post in a related email.
Jim
