Description
Hi Marco,
Usually it indeed happen when the structure of the event definition does
not match the event you send.
In order to analyse the issue could you please send us:
1. The CEP definition file (exported from the Authoring tool)
2. The tomcat log file (under <tomcat installation dir> / log)
3. Proton.properties file (from the <tomcat installation
dir>/webapps/ProtonOnWebServer/config/Proton.properties)
4. The data you send in the POST command and the command header.
I cc the fiware tech help in order to have the issue documented.
Thanks,
Tali

Subject: CEP events
Hi,
I am using CEP Proton in the contest of Finodex challenge. I am having
some problems in sending events through the REST interface.
The error I receive is
Could not parse json event java.lang.NullPointerException, reason: null
Event definition matches my POST request. The demo project works, but not
for new events. I tested it with duplicates of TrafficReport without
success.
Thanks,
Marco

Hi Marco,
My intention was for you to send me the commands you use to configure the
server on your computer, like what definition file to read, and when you
start and stop the server. Examples of commands which I'm talking about:

Hi,
I configured Proton using the web interface.
Anyway, I restarted tomcat and now it works for Test event.
However, if I create a new event, it doesn't work for that event even
after restarting.
Are you able to create events using the web interface? Without importing
models.

Hi Marco,
After consulting with Tali on the matter, we would like to ask you to
clear tomcat's log files, start tomcat over again, do the procedure you
did last time to try to get it working, and then send us the log files and
also details about the REST commands you use to configure proton before

Hello Marco,
I've re-created your scenario on my computer, with your DoSAttack.json
definitions file, and it works fine for me.
Looking at your Proton.properties file, it looks as if your problem is
that the path is absolute (there is no drive or root directory at the
beginning as it seems to me), instead of relative.
Please check again that the routing to your definitions file is correct,
and let me know.
I will note that even if this is the problem, I'm not sure why the error
you're getting is this specific one, but let's try to understand this one
thing at a time.

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.

Hi Marco,
Have you saved AND exported the definitions from the user interface to
/ProtonOnWebServerAdmin/resources/definitions/DoSAttack?
Saving in the Authoring Tool is not enough, as it only saves a local copy
of it in the authoring tool. You also need to export it back to it's
original place for changes to take place.

Hi Marco,
I have tried to replicate your problem on my machine, but without success.
I made a new EPN (defintions file), put it into ProtonWebServerAdmin
through the RESTful API, and then sent events, and they were successfully
processed.
Therefore, I would appreciate if you can write more details about the
whole process you are doing. Especially - I would like to get a screenshot
of your definitions repository that ProtonOnWebServerAdmin uses, and your
definitions file that is stored there that you use.

Hi Marco,
After consulting with Tali on the matter, we would like to ask you to
clear tomcat's log files, start tomcat over again, do the procedure you
did last time to try to get it working, and then send us the log files and
also details about the REST commands you use to configure proton before
you try to send your POST requests.

Hi Itai,
I do not understand what you mean. What should the path be?
Anyway I didn't edit that file, it was created by proton.
thanks
Marco

Hello Marco,
I've re-created your scenario on my computer, with your DoSAttack.json
definitions file, and it works fine for me.
Looking at your Proton.properties file, it looks as if your problem is
that the path is absolute (there is no drive or root directory at the
beginning as it seems to me), instead of relative.
Please check again that the routing to your definitions file is correct,
and let me know.
I will note that even if this is the problem, I'm not sure why the error
you're getting is this specific one, but let's try to understand this one
thing at a time.

Thanks for your answer.
I modified DoSAttack project and duplicated TrafficReport just for
testing. The original TrafficReport works, the duplicate Test doesn't.

Hi Marco,
Usually it indeed happen when the structure of the event definition does
not match the event you send.
In order to analyse the issue could you please send us:
1. The CEP definition file (exported from the Authoring tool)
2. The tomcat log file (under <tomcat installation dir> / log)
3. Proton.properties file (from the <tomcat installation
dir>/webapps/ProtonOnWebServer/config/Proton.properties)
4. The data you send in the POST command and the command header.
I cc the fiware tech help in order to have the issue documented.
Thanks,
Tali

Subject: CEP events
Hi,
I am using CEP Proton in the contest of Finodex challenge. I am having
some problems in sending events through the REST interface.
The error I receive is
Could not parse json event java.lang.NullPointerException, reason: null
Event definition matches my POST request. The demo project works, but not
for new events. I tested it with duplicates of TrafficReport without
success.
Thanks,
Marco
