ConfigurableExample service isn't showed in Kura Web UI [message #1716588]

Hello,
I followed the hello example from the Kura documentation and it seems to work fine.
I followed the configurable example but I'm in troubles.

The configurable example service isn't showed in the Kura services Web UI.

The strange thing is that I can see the bundle in the Active state (from Device -> Bundles menu) but I can't see in the console the message printed by the logger instance as provided by the class implementation.
So ... the bundle is active but the active() method isn't executed ?
I'm using the emulator.
The active() method of hello example works fine.

I can't see any error.

What's the problem ?

Thanks,
Paolo.

Hi Paolo,

If you are running the emulator, please go to the Eclipse IDE Console window and press 'enter'. This should bring up an 'osgi>' prompt. From the prompt enter the 'ls' command and paste the results to the forum. We need to make sure your configurable example is satisfied and being exposed as a service.

Thanks,
--Dave

Hi Dave,
thanks for your reply. I noticed the following ...

If the configuration policy of the ConfigurableExample is set to "require" as documentation describes, this is the output of "ls" command.
As you can see the service is in the list with Unsatisfied state.

ID State Component Name Located in bundle
1 Unsatisfied org.eclipse.kura.example.configurable org.eclipse.kura.example.configurable(bid=1)

27 Active org.eclipse.kura.demo.heater.Heater org.eclipse.kura.demo.heater(bid=54)

If I leave empty the configuration policy in the component.xml, the ConfigurableExample is activated as you can see (Active state) :

27 Active org.eclipse.kura.demo.heater.Heater org.eclipse.kura.demo.heater(bid=54)

However in both cases it doesn't appear in the Kura Web UI.
Any idea ?

Thanks,
Paolo.

Hi Paolo,

For this you want the configuration policy to be "required". The issue appears that ConfigurationAdmin can't find your metatype XML. Did you create all the directories and xml files from the tutorial in your bundle? It should look something like:

/META-INF
/META-INF/MANIFEST.MF
/OSGI-INF
/OSGI-INF/metatype
/OSGI-INF/metatype/org.eclipse.kura.example.configurable.ConfigurableExample.xml
/OSGI-INF/component.xml

The step about including the OSGI-INF directory in your build.xml file is also very important. You should be able to compare your example with the org.eclipse.kura.example.heater project. The two setups should be nearly identical except for the namespace.

Thanks,
--Dave

It's what I have done. It seems that the two projects are identical Sad

Sad

For this reason it's driving me crazy !

I can't find a reason why ConfigurableExample doesn't work properly.

Hi Paolo,

It is almost certainly a typo somewhere. Can you attach your XML files or, preferably, send a link to a Github site with your source files?

Thanks,

For sure ... I agree with you ... there is something I'm missing.
Attached the XML files and the manifest.

Please make sure that your packaged bundle actually contains the resources in the OSGI-INF folder.
Your build.properties should contain a bin.includes entry along the lines of:

bin.includes = META-INF/,\
               .,\
               OSGI-INF/

The build.properties is the following :

bin.includes = META-INF/,\
               .,\
               OSGI-INF/

ID State Component Name Located in bundle

typing comp 1 (or whichever is the ID of the bogus component) may give you more hints on what's actually wrong.
I would suggest you do as Dave said and provide us with a link to a git repo with the full code, as that may help tremendously narrow down the problem.

Hi Paolo,

I was able to get your example running. It is a simple typo, but probably not well described in the tutorial. The issue is in the 'name' field of your component.xml file. The 'name' field must match the id specified in the configuration file. You 'name' field was set to:

org.eclipse.kura.example.configurable

It should be set to:

org.eclipse.kura.example.configurable.ConfigurableExample

I think if you make this change, the example should work for you.

Thanks,
--Dave

Thank Dave,
I found out what is the problems.
I try to save component.xml with:
-Configuration policy: require
- Check box option: This component is enabled when started & This component is immedieately actived.

But it's not really save to my component.xml.

I try to re-saved it again. And it's ok.

Thank you very much, Dave.
