Can not connect to Local Web UI of Kura

Question

I want to install Kura in my computer (ubuntun 14.04, JDK1.7) with eclipse. I followed http://eclipse.github.io/kura/doc/configurable_component.html. My problem is I can not connect to localhost:8080.

In console of eclipse, I inputted 'ss' and its outputs are

"Framework is launched."

Is there anybody ever had this problem may help me, please. Thank you in advance

Answer 1

I can see that you have lots of INSTALLED or RESOLVED bundles, which should be ACTIVE after Kura started. This might be the reason of fail activation of Kura Web UI service. Because the web service might depends on other bundles or services.

So if you still haven't solve it yet, try followings:

1. Change log level by editing /opt/eclipse/kura/kura/log4j.properties file. Set log4j.rootLogger=INFO,kura to log4j.rootLogger=DEBUG,kura. And restart kura.
2. See /var/log/kura.log, there may be some debug messages.
3. See /var/log/kura-console.log, there may be some exceptions that explained why the bundle is not activated.

If you still don't know why, post it here and we can discuss it.

Hope this solve your problem, cheers

Answer 2

I had the same problem... The answer was I downloaded the wrong package. There are 2 Developers Workspaces for download. On the left side without the WebUI. Try to download the Developers Workspace on the right side (Extended Downloads) Developers Workspace (With Web UI) https://www.eclipse.org/kura/downloads.php
