Hi Andres,

We are further looking in to this and we'll fix it for our next release...
For the moment please use Integer data type instead of Long if possible..

We'll track the issue using following jira :
https://wso2.org/jira/browse/CEP-634

Regards,
Mohan

[Dev] parser - java.lang.Long, Problem!! CEP

2013-11-21 Thread andresgomez92 
Hi all,

I have a problem when I try to parse java.lang.Long.

For example:

I send to CEP this json event:

*{timestamp:1383580897,sensor_id:0,sensor_name:pablo06}

where:
  * timestamp is a Long.
  * sensor_id is an Integer.
  * Sensor_name is a String.*

My eventBuilder is like this:

*?xml version=1.0 encoding=UTF-8?
eventBuilder name=builder_rb_monitor statistics=enable
trace=disable xmlns=http://wso2.org/carbon/eventbuilder;
from eventAdaptorName=wso2KafkaConsumer
eventAdaptorType=kafkaConsumerBroker
property name=topicrb_monitor/property
/from
mapping customMapping=enable type=json
property
from jsonPath=$.timestamp/
to default=-1 name=timestamp type=long/
/property
property
from jsonPath=$.sensor_id/
to default=-1 name=sensor_id type=int/
/property
property
from jsonPath=$.sensor_name/
to default=none name=sensor_name type=string/
/property
/mapping
to streamName=rb_monitor_stream version=1.0.0/
/eventBuilder*

and my eventStream is like this:

*streamDefinition name=rb_monitor_stream version=1.0.0
payloadData
property name=timestamp type=LONG /
property name=sensor_id type=INT /
property name=sensor_name type=STRING /
/payloadData
/streamDefinition*

But when I send eventJson in the terminal I can see this:

*[2013-11-20 19:54:51,382]  WARN - {JsonInputMapper}  Unable to cast the
input data to required type :java.lang.Long*

and in the eventTracer I can see:

*19:53:08,286 [-] [pool-12-thread-1]  INFO TenantId=-1234 : Event Builder :
builder_rb_monitor, before processing 
{timestamp:1383580897,sensor_id:0,sensor_name:pablo06}

19:53:08,287 [-] [pool-12-thread-1]  INFO TenantId=-1234 : Event Builder :
builder_rb_monitor : Event Stream : rb_monitor_stream:1.0.0 , after
processing 
[0, pablo06]*

Does anyone know why this happens?

Regards and thanks!

Hi Andres,

I think there is an issue with the json parser. We are using
com.jayway.jsonpath as our json parser for CEP. I think there is a known
issue for Long type when converting, Please see the link [1].. We also
using version 0.8.1 com.jayway.jsonpath. We'll go through this further to
find a possible solution and fix it.. Thanks for reporting..
