Issue with the Web console after upgrading to 2.1-M1

[adimitrov]

Hello Team ,

I have an issue with the web console. I upgraded my 2.0.6 test server to 2.1-M1 and it works, the console manager is working also, but the web application is not.

i get the error:

Not Found

The requested URL /nxmc/ was not found on this server.

Apache/2.2.22 (Debian) Server at 10.10.10.73 Port 80

I just replaced the war files as it is in the admin guide. Java and tomcat7 are running. Getting in the apache error log i can see :

[Mon Oct 17 13:30:08 2016] [error] [client 10.11.10.149] File does not exist: /var/www/nxmc

Why tomcat7 is searching for nxmc folder in /var/www, i know this is the documentroot, but before the upgrade it was working perfectly fine.

Changing the decumentroot in /etc/apache2/sites-enable/ doesn't solve the issue.

Any ideas ?

Thanks,

Best regards,
Adrian

How is your apache tied to your Tomcat?
Are you using just a redirect, or mod_proxy, or something similar?

With default configs, Tomcat runs on 8080, and nothing you do in Tomcat has nothing to do with apache config, nor /var/www nor /etc/apache2/sites-enable/.

You need to look in Tomcat logs, which are usually in /var/log/tomcat/catalina.out (depends on your config tho).

Hi Tomas, team,

it is the default installation of tomcat7 and i never changed a thing in it's configuration.

there is the tomcat7 log:

Seems that the archive was deployed just fine, but still i get the error.

Best regards,

Make sure you are running Java8

[tomaskir]

It seems to me like you are accessing on port 80 (where Apache runs), but you should be accessing on port 8080 (where Tomcat runs).

Make sure you connect using http://server_address:8080/nxmc/.

Hey Victor, Tomas,

I installed jdk8, but still have the issue.

Following Tomas advise it seems that nothing is listening on port 8080:

tcp        0      0 127.0.0.1:8005          0.0.0.0:*              LISTEN      8568/java

tcp6      0      0 :::4700                :::*                    LISTEN      2245/nxagentd

And i get "connection refused" Trying to connect to the web application using the IPaddress:8080/nxmc.

Any idea what could be causing this behavior and how to make it listen to 8080 port ?

Thanks,

Best regards,
Adrian

Hi,

from log and netstat it seems that Tomcat listens only on port 443 (not sure from the log if it expects https or plain http connection though).

Best regards,
Victor

Hello, I want to share my solution for tomcat7:

1. Upgrade to Java8 (Alex recomendation): https://tecadmin.net/install-java-8-on-debian/
2. On  /etc/default/tomcat7 add line JAVA_HOME=/usr/lib/jvm/java-8-oracle, and restart tomcat7 service
3. I deleted my past 2.1-m3 .war's , deploy the new 2.1-m3 .war, and it work

Regards
