Hello,

I am new to Kura
trying to follow this tutorial:
eclipse.github.io/kura/doc/configurable_component.html

blocked on the deployement step, when I install the package on the remote target (Raspberry Pi) it did not show up under services.

Any idea of what I have missed?
Thanks in advance

Hello,

Two things to check:

1. Are there any errors in the logs? Check both /var/log/kura.log and /var/log/kura-console.log.
2. Telnet to the OSGi console and verify your bundle is running. Do this by first logging into the remote target (ssh), then open the console by issuing the command:

telnet localhost 5002

Once you have the OSGi prompt, issue these commands:

osgi> ss
osgi> ls

Your bundle should be in the 'Active' state.

Thanks,
--Dave

Thanks for your reply

No 'Error' in the log file, just INFO and Warn:
WARN o.e.k.w.s.s.SkinServlet - Resource Directory /opt/eclipse/kura/console/skin does not exist
INFO o.e.k.l.n.u.LinuxNetworkUtil - ethtool not found - setting driver to unknown

osgi> ss
70 ACTIVE org.eclipse.kura.example.configurable_1.0.0.201504151414

osgi> ls
29 Active org.eclipse.kura.example.configurableExample org.eclipse.kura.example.configurable(bid=70)

-> my bundle is in the 'Active' state but not shown under services

However I can't access to the web interface administration after launching the OSGI command, had to reboot the Raspberry Pi to access to it, is it normal?

Thanks.
Sabrina

Hello,

After you install and start your bundle, did you refresh the web UI? It does not do this automatically, so you will need to do this to see your service listed.

Two important notes from the tutorial: 1. You must implement the ConfigurableComponent interface with your class; 2. You must expose your bundle as a service to Declarative Services [1].

If you have done these things, I would need to see parts of your code. Maybe post the relevant parts to Github.

Thanks,

Thanks for your help, I did the mentionned notes

Here is my code:

package org.eclipse.kura.example.configurable;

import java.util.Iterator;
import java.util.Map;
import java.util.Map.Entry;

import org.eclipse.kura.configuration.ConfigurableComponent;
import org.osgi.service.component.ComponentContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class ConfigurableExample implements ConfigurableComponent {
	    private static final Logger s_logger = LoggerFactory.getLogger(ConfigurableExample.class);
	    private static final String APP_ID = "org.eclipse.kura.example.configurable.ConfigurableExample";
	    private Map<String, Object> properties;

	    protected void activate(ComponentContext componentContext) {
	        s_logger.info("Bundle " + APP_ID + " has started!");
	    }

	    protected void activate(ComponentContext componentContext, Map<String, Object> properties) {
	        s_logger.info("Bundle " + APP_ID + " has started with config!");
	        updated(properties);
	    }

	    protected void deactivate(ComponentContext componentContext) {
	        s_logger.info("Bundle " + APP_ID + " has stopped!");
	    }

	    public void updated(Map<String, Object> properties) {
	        this.properties = properties;
	        if(properties != null && !properties.isEmpty()) {
	            Iterator<Entry<String, Object>> it = properties.entrySet().iterator();
	            while (it.hasNext()) {
	                Entry<String, Object> entry = it.next();
	                s_logger.info("New property - " + entry.getKey() + " = " +
	                entry.getValue() + " of type " + entry.getValue().getClass().toString());
	            }
	        }
	    }
	}

my configuration file component.xml

<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" activate="activate" name="org.eclipse.kura.example.configurableExample">
   <implementation class="org.eclipse.kura.example.configurable.ConfigurableExample"/>
   <service>
      <provide interface="org.eclipse.kura.example.configurable.ConfigurableExample"/>
   </service>
   <property name="service.pid" type="String" value="org.eclipse.kura.example.configurable.ConfigurableExample"/>
</scr:component>

Do you need to see other code parts?

have a nice day,
sabrina

Try running kura in debug mode: https://dev.eclipse.org/mhonarc/lists/kura-dev/msg00143.html
The project might be throwing an error that it isn't showing you.

Hi all,

Today I ran into the same problem. In order to make your configuration working, you need to introduce one small change to the component.xml. Your service must be registered under the org.eclipse.kura.configuration.ConfigurableComponent interface, not the org.eclipse.kura.example.configurable.ConfigurableExample.

Try to make this change and see what is the result:

   <service>
      <provide interface="org.eclipse.kura.configuration.ConfigurableComponent"/>
   </service>

Issue reported as: Bug 470001

Best regards,
Pawel

Hello John,

Are you getting this error from the emulator or from a physical device? If running from an emulator, which platform are you using (Linux or OSX)?

Thanks,
Dave

Hi Folks,

Based on the bug 47001, this is not the good answer.
Did you find the answer fixing this issue?

Thanks a lot

Hello,

Bug 47001 was closed as invalid. Can you please provide the following information:

1. Kura Version
2. Target hardware (Emulator, Raspberry Pi, etc.)
3. Output of OSGi console 'ss' command
4. Output of OSGi console 'ls' command

Thanks,
--Dave
