Description
Hi all,
i have some troubles integration Orion and CEP
Orion version:
Name : contextBroker
Arch : x86_64
Version : 1.2.0
Release : 1
Size : 3.8 M
Repo : installed
From repo : testbed-fi-ware
Summary : Orion Context Broker
URL :
http://catalogue.fiware.org/enablers/publishsubscribe-context-broker-orion-context-broker
License : AGPLv3
Description : The Orion Context Broker is an implementation of NGSI9 and
NGSI10 interfaces.
: Using these interfaces, clients can do several operations:
: * Register context producer applications, e.g. a temperature
sensor within a room.
: * Update context information, e.g. send updates of
temperature.
: * Being notified when changes on context information take
place (e.g. the
: temperature has changed) or with a given frecuency (e.g.
get the temperature
: each minute).
: * Query context information. The Orion Context Broker stores
context information
: updated from applications, so queries are resolved based on
that information.
CEP version: the one installed with the image cep-r3.3.3-img
<https://cloud.lab.fiware.org/#nova/images/91ea7bbc-714c-403c-930d-e575a8c81916>
I have subscribed CEP to Orion updates, and i got the following error in
catalina.out
Tue Jun 14 10:53:42 CEST 2016 - Archon1 loaded sucessfully

This is data definition in CEP:

{"dimension":0,"name":"entityId","type":"String"}],"createdDate":"Mon

2016"}],"name":"Archon1","consumers":[],"epas":[],"contexts":

This is the definition on Orion:
{
"contextResponses": [
{
"contextElement": {
"attributes": [

,
{ "name": "temperature", "type": "float", "value": "23" } ],
"id": "Room2",
"isPattern": "false",
"type": "Room"
},
"statusCode":
}
]
}
Can you help me on this topic?
Thanks
Daniele

Last question we got for Uri to answer:
Comment by ds@archon.ai :
Orion sends this data to CEP:
POST /ProtonOnWebServer/rest/events HTTP/1.1
User-Agent: orion/0.28.0 libcurl/7.19.7
Host: 192.168.100.155:8080
Accept: application/xml, application/json
Content-length: 902
Content-type: application/xml
<notifyContextRequest>
<subscriptionId>575fd8b6d57eb098cfd3c17e</subscriptionId>
<originator>localhost</originator>
<contextResponseList>
<contextElementResponse>
<contextElement>
<entityId type="Room" isPattern="false">
<id>Room2</id>
</entityId>
<contextAttributeList>
<contextAttribute>
<name>pressure</name>
<type>integer</type>
<contextValue>713</contextValue>
</contextAttribute>
<contextAttribute>
<name>temperature</name>
<type>float</type>
<contextValue>23</contextValue>
</contextAttribute>
</contextAttributeList>
</contextElement>
<statusCode>
<code>200</code>
<reasonPhrase>OK</reasonPhrase>
</statusCode>
</contextElementResponse>
</contextResponseList>
</notifyContextRequest>
And the error is as follows:
INFO: started event message body reader
20-jun-2016 10:35:48
com.ibm.hrl.proton.webapp.providers.EventXmlNgsiMessageReader readFrom
*GRAVE: Could not parse XML NGSI event java.lang.NullPointerException,

Still looking into this issue and will respond soon with more clarifications.
Thanks,

As far as we can see, the user is sending JSON NGSI events which Proton doesn't support.
It will help if the user shares how notifyContextRequests notifications sent by ContextBroker look ?
(just to make sure it is indeed JSON and not XML)
Thanks.
Hi Daniele,
This tickets has been created to give you support for CEP questions since Fermin, Orion GE Owner informs last questions are related to CEP.
Thanks.
