CEP events

[Marco Stenico]

Hi,

I use only start/stop instance command. I configure Proton using the user
interface.
I created a project, but I am having the same problems also with the demo
project DoSAttack where I created a new event.
The instance runs because the status is started and I can send previously
defined events with success.
What I can't do is to send new events. In one case restarting tomcat solved
the problem, but now this trick doesn't seem to work anymore.

PUT
http://MY_IP/ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer
data {"action":"ChangeState","state":"start"}

GET
http://MY_IP/ProtonOnWebServerAdmin/resources/instances/ProtonOnWebServer
output:
{
  "state": "started",
  "definitions-url":
"/ProtonOnWebServerAdmin/resources/definitions/DoSAttack"
}

POST http://MY_IP/ProtonOnWebServer/rest/events
{"Name":"TrafficReport", "volume":"123"}
*WORK!*

POST http://MY_IP/ProtonOnWebServer/rest/events
{"Name":"NewEvent", "volume":"123"}
*DOESN'T WORK!*


Thanks,
Marco
