NetXMS Support Forum

Also, I should mention that I also couldn't get it to work with java 7.

So I added
deb http://ftp.debian.org/debian jessie-backports main
to /etc/apt/sources.list

Installed
apt-get install -t jessie-backports openjdk-8-jre-headless ca-certificates-java tomcat8 tomcat8-admin

And deployed it using the web manager interface that is linked from the default tomcat webpage.

I also upped the memory and cache sizes based on message I saw in the logs.

Thread right below this one about web interface on CentOS addresses this problem.

TL;DR;

Try installing the war file using the manager interface that you can install along with tomcat.

So instead of loading the file into the webapps directory I deployed it through the manager interface in the browser. That seems to work fine. Not sure what the difference is, but it worked the first time and it seems the problem is solved.

I am trying to install the webui on a debian 8 container and I'm having the same issue. Getting a 404 error. I've tried increasing memory, but no luck. The app does show it's running on the tomcat manager interface, and the only other error I can find in the log is a message about increasing cache size.

Anyone know where I should look next.
