Re: [paho-dev] Paho plans

At sierra we built a somewhat custom java mqtt server.
The asynchronous mqtt protocol encoder/decoder can be found here:
https://github.com/jvermillard/mqtt-experiment
IMO it's a good start for a java based mqtt broker, but I'm not sure to get the point to compete against, mosquito, rsmb and ponte.

I didn't hear any lack of committment from the project leads. I think they are simply being pragmatic in explaining that so far there isn't any Java server side code so far. I think you *could* wrap C code but it would be (in my opinion) a really bad idea. 

I think the thing is to start a Java MQTT project, and I'm willing to collaborate.

Hi Mike,
I happen to disagree with the wisdom of the Board's definition, but that doesn't have to do with anything...as I'm not questioning based upon impl language...I don't really care what language it's written in. 
What I do care about is being able to use a framework provided by another EF project...seems to me that everyone should want other EF projects as consumers...but I guess community means different things to different people/companies.
As I've already made clear, I would be one such contributor for a java based Mqtt broker...but sadly, without the commitment of the project leads that seems unlikely to happen for a new project in incubation
I never said anything about a requirement. I simply thought that a new project might want some consumers/community members/supporters. 
In the mean time ECF has little choice other than to use the work of other, non-EF projects in this area. Not what we would prefer to do.

Scott,
The "powers that be" would be referring to the Eclipse Board.
Your viewpoint on what defines an Eclipse project is out of date. The Eclipse Board decided quite some time ago that we are willing to accept projects based on languages and platforms other than Java and OSGi. (Sorry, I'm on my phone or I'd provide a link. I'll do that in the morning. )
If sufficient contributors show up willing to create a Java MQTT broker as part of Mosquitto, that would be great. But there is no requirement for the existing project to port to Java.

I'm not sure who you are referring to with the 'powers that be'. Could 
you explain?
I have no objection to using C as an implementation 
language...particularly as I imagine it could provide size and/or 
performance benefits. But it would be nice if it also ran on the EF 
runtime platform (OSGi framework) so that other EF projects could 
actually use it as a framework. Currently that's not possible...i.e. 
the vast majority of EF projects can't even use the framework. This 
severely limits the usefulness to other EF projects...which hopefully 
are at least a desired consumer of this work.
I'm not asking that the C implementation be at all 
abandoned...rather...why not do what SWT did...and provide a java API 
that uses the C implementation? Like I said, I would be willing to 
contribute to such an effort...so that other EF projects could actually 
consume/use this framework (ECF in my case, but I suspect that other 
projects could be interested also).
Note I'm not asking this for the IDE/tooling per se...rather ECF is a 
runtime project, and is primarily focused on supporting OSGi runtimes 
and standards (e.g. OSGi remote services). So this request isn't about 
the IDE...or even tooling more generally. A lot of work in the RT 
project at EF is focused on OSGi server development, and in the abstract 
M2M would be an ideal combination IMHO...lightweight brokers for 
modular, lightweight OSGi servers.
All I'm asking is that you look to other EF projects as a prospective 
community, and make it possible for them/us to consume this work. Not 
that the existing codebase be abandoned or rewritten.
I'm of the opinion that supporting other EF projects should be some sort 
of metric for all EF projects...so that we don't end up a loose 
collection of unrelated projects...with no/little relationship other 
than that we are hosted at eclipse.org...but that's just my opinion.
