Re: [ecf-dev] Remoting with ECF (with REST) in Eclipse RCP?

When I see ECF samples, there is a lot of Java code to do in the
Activator. In my case I would like just using Spring file to declare
the client and server side.
The ECF Spring support problem is client side (not server side). On
client side if you configure an URL of the server and you start the
client BEFORE the server, the Spring bean cannot be created.
That's is the first problem (I will try to fix that if we decide to
use ECF in our project).
ECF remote services is an implementation of the OSGi remote services
specification...and as such simply makes available remoting for services
registered (with appropriate properties) in the OSGI service registry.
This registering of services can be done in java, ds, and...I'm quite
certain...Spring. ECF has examples of doing it with java, and ds (for
ds examples, see):
for host:
http://git.eclipse.org/c/ecf/org.eclipse.ecf.git/tree/examples/bundles/org.eclipse.ecf.examples.remoteservices.hello.ds.host
for consumer/client:
http://git.eclipse.org/c/ecf/org.eclipse.ecf.git/tree/examples/bundles/org.eclipse.ecf.examples.remoteservices.hello.ds.consumer
The ECF Spring support that was previously done (that I think you are
referring to) is no longer needed...now that ECF implements the OSGi
remote services spec (when that work was done, the standard did not
exist...and so our impl of the standard did not exist).
So you should be able to use Spring (just like ds examples) to declare
both your service host and consumer host...and how/when that's done (by
Spring...or ds) will determine the timing of the availability of the
service for remote access.
The second problem is that ECF seems not support JAX-RS (just REST).
JAX-RS is not 'REST'. It's a standard/implementation. Restlet is
listed here
http://en.wikipedia.org/wiki/Java_API_for_RESTful_Web_Services
as an implementation of JAX-RS, and ECF has a provider based upon
Restlet here
https://github.com/ECF/RestletProvider
So without getting into specifics of the JAX-RS standard, versions, and
compatibility tests, etc I would say that we in fact do support JAX-RS
through our use of Restlet as a JAX-RS implementation.
As I said you, I don't want code something. I give you how I do that
with CXF and I hope you will understand my need.
To be direct about it, I guess I don't understand your need. As for
'coding' or not...like I said...ECF remote services simply implements
the OSGi remote services specification...and so *any* mechanism for
registering and accessing OSGi services (java, ds, Spring, etc) is
suitable for using for remote services. No java code required...if not
desired.
The existence of the ECF Spring support (done in java, before the spec
and impl existed as I said) may be confusing here as I think it implies
that this is the only way to use ECF remote services with Spring.
That's no longer true.
