I am new to OpenNMS and did today an install just like described here:
The only differences are the OpenNMS Version (mine is 16.0.0-1) and it seems that this version of OpenNMS doesn't support Java7, so I installed Java8. Everything went fine and I had no errors, since I try to login via web-browser. Instead of a login page I receive a:
HTTP ERROR: 503
Problem accessing /opennms. Reason:
Powered by Jetty://
I did a few goole searches and came about this:
So I did an uncomment of the "pollerBackend" as described in the woraround (at this moment I noticed that I have the service-configuration.xml file twice. One in /etc/opennms/ and one in /var/lib/opennms/etc-pristine/. So I modified both) and moved the opennms-remoting folder.
But still getting the same error.
Anybody with an idea, how to troubleshot this further.
Thanks in advance
