MQTT transport for Axis2

[Pradeep Fernando <pr...@gmail.com>]

Hi Devs,

MQTT is an application layer broker based pub/sub protocol built on top of
TCP/IP. It is very lightweight and hence ideal for usage in
network/memory/computing power constrained environments. If I quote the
MQTT spec, the protocol features,

   1. Pub/Sub message pattern
   2. Small transport overhead, fixed length header being only 2 bytes
   3. Supports three QOS for message delivery, at-least once, exactly once
   and at-most once.

The ability to operate under constrained environment make this protocol an
ideal candidate for embedded device communication/pervasive computing.

I managed to implement a working axis2 transport using MQTT java client
library provided by Eclipse Paho project.  The code can be found at [1]. I
have also written a blog post to get the code up and running [2]

I would like to contribute/Improve the new transport to Axis2/Synapse. How
should I proceed.
appreciate your feedback.

Hi Sagara,

Thanks for the feedback.
Will create a proper patch against the axis2 trunk and attach. Yes I have
to work on test cases. Will start working on that aspect as well.

thanks,

This can be a good addition to Axis2 transport module. I'm not quite sure
about EPL ( which used by the Eclipse Paho) is compatible with Apache if
there is no issue then you can contribute your codes to Axis2 project.
Please create a JIRA and attach your SVN patch against current trunk. One
thing I noticed is you have to provide more test cases for this transport
implementation.

Thanks !
