Subject JaxRS Remote Services using latest Jersey or Apache CXF
Date Wed, 27 Feb 2019 04:59:21 GMT
Hi Folks,

There's a new version of the ECF JaxRS Distribution Provider [1].   This 
provider implements OSGi R7 Remote Services [2] via the JaxRS support in 
new Jersey 2.28 or Apache CXF 3.3.

In practice, this means that any JaxRS-annotated service can be exported 
as a spec-compliant Remote Service in Karaf or other environments by 
adding service properties on service registration.   An example of 
running such an example in Karaf is documented here [3] with all example 
source available here [1].

Both Jersey and CXF can be extended and/or configured to support custom 
serialization, security, or other use-case specific distribution needs, 
all within the JaxRS-standardized extension mechanisms.

OSGi R7 Remote Services has asynchronous remote services [4], service 
intents, remote service admin, configurable and extensible service 
discovery, and service dynamics, as well as versioning, proxy 
creation...all integrated-via spec with any frameworks built upon the 
OSGi service registry (DS, etc).

ECF also now has a Bndtools 4.2+ workspace and templates for creating 
and running remote services with Bndtools [5].  These provide the repos 
for the necessary bundles, as well as runnable examples and bndtools 
project templates.

See blog posting [6] for more links.

Thanks,

Scott
