Thanks Antonio...

I used default configuration file, and maps page started...

Thanks -

What I see in the logs is some error in map.properties.
So I guess you have a broken map.properties. Try out a default map.properties.

Hi,
I have ONMS 1.8.11 and i am facing the same error message, and failed to initialize maps.

Error is given below by opening http://localhost:8980/opennms/MapStartUp.map
