Re: [osgi-dev] osgi broker bundle

[Christian Schneider]

I was not suggesting to use karaf. But looking into the karaf features 
can help with the setup for bndtools.
For eclipse paho you just need to download this one bundle and put it 
into your index but paho does not give you a broker it is only the client.


For mqtt I typically use the mosquitto broker. It is written in C and 
very small. So it runs very well on small hardware. Most linux distros 
already provide a package for it.

ActiveMQ is not a good choice for MQTT. It needs a lot of
dependencies.
If you just need a client I would try eclipse paho first.

In karaf it is just this:
install -s mvn:org.eclipse.paho/org.eclipse.paho.client.mqttv3/1.1.0

For bndtools you have to put that bundle into an index first of
course.

Re: [osgi-dev] osgi broker bundle

[Mestiri Meher]

Hello guys,

I was able to bundle the ActiveMQ and push it into the Apache Felix context.
It was not really so hard after all. I'll prepare a video-tuto about it and
share it with you near. It's not complicated.

But right now I have another issue :)

Here is the scenario : 1/ I created the ActiveMQ bundle inside apache
felix, I run it and it listens to the needed port. 2/ I created the
producer bundle and putted all the needed connection and queue creation in
the start method. 3/ I created the consumer bundle following the same
strategy Once I start the producer, I can see my message sent. Once I run
the consumer it's ok I can see the message received, the issue is once I
stop the producer bundle and I restart it, I was waiting to get a
notification from my consumer bundle but not, I do have to restart the
consumer so it knows about the new message and throw it out. Do you have an
idea on how could I get notified by my bundle once a new message pushed
into the broker queue ?


I'm thinking about the fact that I did not used the multithreading, but I'm
not sure, in the activeMq tutos it creates the producers/consumers using
threads.
So probably that's the issue..

Do I have to register my bundle in the osgi service registry ?!


Thanks all for your help and sharing about osgi!

Re: [osgi-dev] osgi broker bundle

[chris . gray]

As I said I haven't tried Moquette yet because I didn't yet have the need
to run an MQTT broker in an OSGi context. However the developer
specifically mentions the *possibility* of "running inside an embedded
OSGi broker like Concierge" so it would be worth contacting him about it.

https://projects.eclipse.org/proposals/moquette-mqtt

If you want to run a broker on an embedded device then probably your
device is some kind of "gateway" between a local network of
sensors/actuators and some kind of "cloud", am I close? In that case I
must say "Welcome to the Fog". :-)

In this use case you probably want your own broker to act in "bridging"
mode, and then you will find that mosquitto is not very dynamic - to
change the bridging configuration you need to stop mosquitto, update the
mosquitto.conf file and restart it, a mere "HUP" is not enough.  So any
OSGi service you create to control the mosquitto lifecycle is going to be
pretty ugly.

Whether Moquette is any better in this case remains to be seen, if the
developer's idea of OSGi is "slap on an Activator and a manifest" then
you're not much further ... how much this all matters depends on your use
case and how much dynamic behaviour you need ...

Hi,

I second that, and I can tell mosquito works out nicely for me.
If you look for a tool to investigate what data is sent to your mqtt
broker, I suggest mqttfx.
It's a nice tool to investigate your broker.

If you really only need MQTT then I think you should be looking at a
dedicated MQTT broker rather than an all-singing, all-dancing message
boroker like ActiveMQ. Moquette looks promising (caveat - I haven't tried

Sounds like it wants Blueprint. Maybe just the API package, maybe the implementation. I would not expect a Blueprint implementation to run in jre embedded.

Hi guys,
 
I'm looking on how deploying an MQTT broker into an osgi environment.
 
I'm running my osgi container in an embedded environment.
 
I tried installing apache Karaf as it already has the ActiveMQ broker integration easy, but i was not able to install it as it needs some junit libraries that does not comply with the jre embedded.
 
The other solution I'm thinking of is installing the ActiveMQ broker against Felix.
 
I found in an mvn repo an osgi bundle for the activeMQ but it needs its dependencies.
 
So I tried adding them as bundles but I faced an issue right now because when I start that bundle it asks for a dependency that I can't find it.
 
->  Unable to resolve org.apache.activemq.activemq-osgi version=5.14.3:

Do you have an idea on how I have to proceed ?

[osgi-dev] osgi broker bundle

[Mestiri Meher]

Hi guys,

I'm looking on how deploying an MQTT broker into an osgi environment.

I'm running my osgi container in an embedded environment.

I tried installing apache Karaf as it already has the ActiveMQ broker
integration easy, but i was not able to install it as it needs some junit
libraries that does not comply with the jre embedded.

The other solution I'm thinking of is installing the ActiveMQ broker
against Felix.

I found in an mvn repo an osgi bundle for the activeMQ but it needs its
dependencies.

So I tried adding them as bundles but I faced an issue right now because
when I start that bundle it asks for a dependency that I can't find it.

->  Unable to resolve org.apache.activemq.activemq-osgi version=5.14.3:
   missing requirement org.osgi.service.blueprint; version=[1.0.0,2.0.0)]

Do you have an idea on how I have to proceed ?

Thanks in advance :)
Meher
