Kura WebUi giving 404 [message #1731533]

We installed Kura (kura_1.4.0_beaglebone-nn_debian_installer.deb) on Beaglebone Black. But after installation the WebUI is giving 404 error:

Problem accessing /. Reason:

    ProxyServlet: /

We followed this link and checked the state of bundles. We could see that kura web was not ACTIVE:

65      INSTALLED   org.eclipse.kura.web_1.0.7

So we tried starting kura web using OSGI console like this:

osgi> start 65                                                                  
gogo: BundleException: The bundle "org.eclipse.kura.web_1.0.7 [65]" could not be
 resolved. Reason: Missing Constraint: Import-Package: com.allen_sauer.gwt.log.c
lient; version="0.0.0"

Can someone let me know if this is the core issue? why is "allen_sauer.gwt.log.client" missing? How can I add it?

Attached OSGI log.

Hello,

I just did a fresh install and the web bundle started and worked as expected. Can you confirm that you downloaded using this link [1] from the "Extended Downloads" section?

[1] https://s3.amazonaws.com/kura_downloads/debian/release/1.4.0/kura_1.4.0_beaglebone-nn_debian_installer.deb

Thanks,
--Dave

Yes. Thats the one I installed. But after your reply, I installed it again:

md5sum kura_1.4.0_beaglebone-nn_debian_installer.deb
c3b595a0ad9566f599b847b4f2d6bd17  kura_1.4.0_beaglebone-nn_debian_installer.deb

But I am getting the same error.

This is my setup:

BBB revision: C
Debian GNU/Linux 7 (Wheezy)
Java:

# java -version                                                
java version "1.6.0_38"                                                         
OpenJDK Runtime Environment (IcedTea6 1.13.10) (6b38-1.13.10-1~deb7u1)          
OpenJDK Zero VM (build 23.25-b01, mixed mode)

I had switched to wheezy ( from jessie ) due to wifi issues. I was unable to enable Edimax wifi dongle.

Java was installed using the command:

apt-get install default-jre

If you need any more info please let me know.

Hello,

Can you please check the log files (/var/log/kura.log and /var/log/kura-console.log) for any errors? Can you post the output of this command: netstat -tulpn

Fixed this by upgrading java.

echo "deb http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee /etc/apt/sources.list.d/webupd8team-java.list
echo "deb-src http://ppa.launchpad.net/webupd8team/java/ubuntu xenial main" | tee -a /etc/apt/sources.list.d/webupd8team-java.list
apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys EEA14886
apt-get update
apt-get install oracle-java7-installer

Thanks for the help.
