Does anyone know how to use java api to achieve anomaly detection with Thingwatcher8.0?

[weli]

Please see my code in attachment,the output of my code is:

CALIBRATING

WAT9999E

Unexpected exception. {Throwable=[NullPointerException: }]

Is isAnomalousValue false

ThingWatcherStat FAILED

It indicates after calibrating the thingwatcher failed.

I used jar install to run resut and training Microservices.  I can see log from training microservice

com.thingworx.analytics.training.core.TrainingRunner: Successfully stored PMML to modelUri "Optional[http://192.168.31.202:8090/results/models/1/models.xml]" for jobId "1"

But I see error in result microservice:

Hi

As indicated here is an update on fixing the issue.

The

WAT9999E

Unexpected exception. {Throwable=[NullPointerException: }]

exception is due to the use of t.getMessages().getMessages()

When everything works fine, there will be no message and it will be set to null. hence the call to null.getMessages report the NullPointerException.

To avoid this  call instead toExtendedString()

See attached modified code

Thanks
