[paho-dev] standard Remote Services over Paho MQTT
|
Howdy,
First, congrats to the Paho team on releasing v1.0.
Earlier this year, ECF implemented a remote services provider [1], based
upon the Paho 0.5.0 java client library...which at that time had to be
embedded inside the provider bundle, because Paho 0.5.0 was a plain 'ol
jar rather than an OSGi bundle.
Now that the Paho 0.9.0 Java client is available as an OSGi bundle
(thanks!), we have moved over to the 0.9.0 mqttv3 bundle and
successfully tested the provider using our remote services test suite.
What this means is that developers can create, test, debug, and deploy
standard OSGi Remote Services (chapter 100 in enterprise spec), and then
run them on MQTT, JMS, REST, or other/custom/private protocols. As per
spec, they may even switch among protocols at runtime, if they so
prefer, to meet application-specific security, interoperability, and/or
bandwidth requirements/restrictions. Or they can develop and test on
one protocol and switch to another protocol for deployment. All the
while maintaining compliance with the OSGi Remote Services
specification, and thereby being fully transport independent at the
level of arbitrary OSGi services.
Another thing this means is that the remote services examples and
tutorials [2] will run unmodified on this provider. We will be adding
the use of this new provider to these examples and tutorials before
release with ECF 3.9.0 in early August.
