如何测试Fiware Cygnus

Question

I installed Fiware Cygnus on my Ubuntu 14.04 using this link [1] and I am following this tutorial [2] to test it.

But when I get to the step of sending a notification such as:

$ ./notification.sh http://localhost:5050/notify

I get "connection refused" error.

Note: while starting cygnus I got the error bellow: I dont know what have I missed.

Thanks in advance for your help!

如果您尝试使用的Cygnus版本是0.8.2，则您的问题可能与我相同，请参见Cygnus启动错误：ClassNotFoundException
