exception during aborting jBPM6 process

[pandyajayn]

Hi,

i am getting following exception while aborting the process,

please note my code is already in QA environment with all other functionality working, am getting exception only for aborting the process.

I am using REST API for interaction with jBPM

org.jboss.resteasy.client.ClientResponseFailure: Unable to find a MessageBodyReader of content-type text/html;charset="utf-8" and type null

while calling

kSession.abortProcessInstance(processInstanceId);

thanks in advance

Regards,

Jay
