Introduction
New: ECF OSGi R7 Remote Services. The R7 Remote Services adds the standardization of several intents. One of those intents is the [osgi.async intent], which allows remote services to be invoked asynchronously (non-blocking) rather than synchronously (blocking). Supporting async and the other standardized intents: osgi.basic, osgi.private, osgi.confidential requires a distribution provider that supports that intent. For each distribution provider below, the currently supported intents are listed. To request support for an unsupported intent, please post the request to the ecf-dev mailing list.
The Remote Services/Remote Service Admin specifications (chaps 100 and 122 in OSGi Enterprise spec) allows for the use of multiple distribution providers. Distribution providers are responsible for the actual marshalling/serialization and network communication when a consumer invokes a remote service method.
The ECF Architecture also allows the use of multiple distribution providers. Further, ECF's open APIs and implementations supports the creation of custom distribution providers using any desired transport protocols, serialization formats and/or libraries.
Remote Services API
ECF's API for distribution providers is the Remote Services API (RSAPI). Implementing this API is the only requirement to create a RS/RSA standards compliant distribution provider. All of the distribution providers implement the RSAPI.

The two r-OSGi providers: ecf.r_osgi.peer.ws, and ecf.r_osgi.peer.wss are supported by adding two additional bundles: ch.ethz.iks.r_osgi.transport.http, and Java Websocket. These two bundles are available in the ECF Github Websockets Repo, at the following paths:
ch.ethz.iks.r_osgi.transport.http: bundles/ch.ethz.iks.r_osgi.transport.http
java_websocket: bundles/java_websocket
Recent build of these bundles is available here

Jax-RS Providers
The ECF team has created several REST-based Remote Service providers, all of which are based upon the Jax-RS specification. By using OSGi Remote Service standards along with Jax-RS standards, it's possible to create remote services that can be used on any compliant Jax-RS implementation, and any RSA-compliant Remote Services implementation. For a tutorial on how this can work, see the tutorial Using REST and OSGi Standards for Micro Services.
Since REST is based upon a client-server model of services, Remote Services based upon rest may only be exported on servers. Clients may import, but are unable to export Remote Services.

Providers created via ECF REST API
ECF has provided an API to aid in the creation of REST-based Remote Services provider. Using this API, it's possible to create a Remote Service client/proxy that uses an existing REST-based service. Thus new Remote Services can be created to expose an existing REST-based service. The following tutorial: ECF Remote Services for Accessing Existing REST Services describes how to use the ECF REST API to create client provider to access an existing REST service.
OSGi Service Exported Configs
ecf.rest.client
As mentioned above, only REST servers may export Remote Services, so the ecf.rest.client provider may not export Remote Services.
