Problem installing Kura 1.2.1 [message #1706178]

Hi,

i've tried to upgrade my Kura installation from 1.2.0 to 1.2.1 but afterwards i couldn't access the Web-UI anymore.
So i tried to install it on a fresh raspbian installation (Raspbian (Model 2, with Web UI) - Stable) which led to the same problem.
When i'm trying to access the Web-Ui then there is only the message:

HTTP ERROR: 404
Problem accessing /kura. Reason:
ProxyServlet: /kura

kura.log contains no errors messages.
kura-console.log contains an error message which says that jdk.dio_1.0.1.jar is missing (i fixed this by adding the missing jar but this didn't resolve the 404 error)

Can you give me any advise how to fix this or is the current build broken?

Thanks and regards
Michael

Hi Michael,

The probable reason of getting such a 404 error is that the web container bundle inside the Equinox OSGi container doesn't find any servlet on "/" (web root). It is because of the delay of the bundles to get started after a device restart or a bundle update. I would suggest you to restart your machine and wait for few minutes after the restart to boot up Kura successfully.

If this doesn't solve your problem, execute the following command on the console.

telnet localhost 5002

This will get you inside the Kura's Equinox Console and once you're inside the OSGi console, execute ss command. This will enlist all the bundles deployed in the Equinox container. Here you should see all the bundles must be in the ACTIVE state unless you have any fragment bundle which would be in RESOLVED state.

Execute the ls command as well which will enlist all the Declarative Services Component in the container. Here you will find all in ACTIVE state as well.

If you find any discrepancy in the outputs of both the commands, it would be good if you can post it here.

Hope it helps.

Hi Amit,

i waited some time after restarting the pi as you said but unfortunately nothing changed and the error message keeps the same.I already had a look at the bundle states bevore but there was nothing which looks suspicious for me.
Nevertheless i attached the output of the two commands.

Thanks and regards

Michael

--------- EDIT: ---------------

I found the problem. Comparing the list of bundles of my running 1.2.0 installation with the 1.2.1 one I discovered that the kura.web bundle was missing. I checked the prebuild .deb files and none of them contains the kura.web bundle. Maybe something went wrong while building the packages or creating the links.

I installed the kura.web bundle via the osgi console which solves the problem.
I will try to build the current version of the bundle from source now.

Oh I see. I think you have built Kura without the web bundle.

Build with CAN support

mvn -Dmaven.test.skip=true -f manifest_pom.xml -Pcan clean install

Build without CAN support

mvn -Dmaven.test.skip=true -f manifest_pom.xml clean install

Build with web UI

mvn -Dmaven.test.skip=true -f pom_pom.xml -Pweb clean install

Build without web UI

mvn -Dmaven.test.skip=true -f pom_pom.xml clean install

Just for your reference.

Just to make things clear Smile

. I didn't build Kura from source but i used the provided installers from here:
http://www.eclipse.org/kura/downloads.php

All packages I checked don't contain the web bundle although the description says they do (like "Raspbian (Model 2, with Web UI) - Stable" for example).
The previous versions from the download page worked without a problem.

Due to this problem i built Kura from source now which worked without problems.
Thanks for your help Amit!

Then I think it needs to be reported to the Kura Dev Team for the correction. Anyways you are welcome and also thanks for such a good finding. It will surely help Kura Team to rectify the discrepancy.

Hello,

Please check the log files (/var/log/kura.log and /var/log/kura-console.log) for any errors. Also, login to the OSGi console and report the output of the 'ss' and 'ls' commands.

Thanks,
--Dave

Hello,

The easiest way is to browse to the IP address of the unit where Kura is installed. For most platforms, this is hosted on port 80. If you are using the Intel Edison distribution, the port will be 8080.

You can also login to the OSGi console and issue the ls command. You should see something like:

38 Active org.eclipse.kura.web.Console org.eclipse.kura.web(bid=82)

Thanks,

Hello,

The Kura installers are tested against specific platforms (Raspberry Pi 2/3, Raspberry Pi B+, Intel Edison, etc.). Kura has native libraries which are compiled for specific architectures. My guess is the native libraries are not loading for your platform. You can verify by checking the contents of /var/log/kura-console.log. There are several posts in this forum for compiling the needed libraries for different architectures.

Thanks,
--Dave
