> +Question:+
> Cygnus startup error: ClassNotFoundException
> +Description:+
> My environment is VM with CentOS 6.6
> I followed the instruction in https://github.com/telefonicaid/fiware-cygnus/blob/master/doc/quick_start_guide.md to install Cygnus. java-1.6.0-openjdk-devel was also installed and the JAVA_HOME set.
> Installation went fine and it installed package cygnus.x86_64 0:0.8.2-0.g7353160
> To test Cygnus I created the agent_test.conf and notification.sh files as instructed. When I start Cygnus, it outputs following stuff:
> [root at localhost ~]# /usr/cygnus/bin/cygnus-flume-ng agent --conf /usr/cygnus/conf/ -f /usr/cygnus/conf/agent_test.conf -n cygnusagent -Dflume.root.logger=INFO,console
> + exec /usr/lib/jvm/java-1.6.0-openjdk.x86_64/bin/java -Xmx20m -Dflume.root.logger=INFO,console -cp '/usr/cygnus/conf:/usr/cygnus/lib/*:/usr/cygnus/plugins.d/cygnus/lib/*:/usr/cygnus/plugins.d/cygnus/libext/*' -Djava.library.path= com.telefonica.iot.cygnus.nodes.CygnusApplication -f /usr/cygnus/conf/agent_test.conf -n cygnusagent
