I'm interesting in implement OpenNMS but i have some problems that doesn't makes me advance, and the documentation is poor in examples to a beginner like me.

The problem exactly is with the link representation on the map. I configured the "linkd", enabled it on the "service-configuration" and also configured the "Map Adapter Configuration" and the "Link Adapter Configuration" too, but in the web ui doesn't appear the links.

Other problem is when i pick the "Node Ip Route Info" on the router (cisco) node page, i get the following error:

java.lang.NullPointerException
at org.apache.jsp.includes.nodeRouteInfo_002dbox_jsp._jspService(org.apache.jsp.includes.nodeRouteInfo_002dbox_jsp:106)

and more...

I don't know if due to this error, the OpenNMS server can't obtain IP routes, can't update the database of links, and consequently can't represent the links on the maps.

Could you please help me?

Best regards,

Alejandro
