Hi all,

   I am new to the concept of JSON. I was trying to start a new process using the following URL:

*http://192.168.1.1:8080/wflow-wfweb/web/json/workflow/process/start/email_check#1#e_mail_process?j_username=chait&j_password=XXXX*

I am getting following output:

"{"activityId":"","processId":""}"

i.e. no activityId or processId is being shown.
And in logs, there is NullPointerException error. I am not understanding what is the problem.

Thanx.
