Fiware Cygnus Handler Not Found

Question

I have done a clean installation of Fiware (Orion ContextBroker, MongoDB, Java JDK & Cygnus) on a CentOS 6.9 machine. But i got a problem with Cygnus, i cant get him start. When i try anything, event the Quick Start Guide Test i got the following error :

java.lang.ClassNotFoundException: com.telefonica.iot.cygnus.handlers.OrionRestHandler

Do you know what the problem is? Thanks !

Answer 1

OrionRestHandler was the name of the Http handler in charge of parsing NGSI notifications until 0.13.0 version. From 1.0.0 its name is NGSIRestHandler.

The same occurs with the name of the sinks, a OrionXXXSink is now NGSIXXXSink.

Sinply replace the old names with the new ones if you are using a recent version of Cygnus.
