Jasper Report remove login credentials from URL

[nithinabaq.us]

Hi,

   I am calling report service using rest api like http://localhost:8080/jasperserver/rest_v2/reports/reports/samples/testNew.html?deviceID=9876543210&fromtime=2014-01-01+00:00:00&totime=2014-06-01+00:00:00&accountID=demo&j_username=jasperadmin&j_password=jasperadmin . how can i avoid j_username=jasperadmin&j_password=jasperadmin  so that i dont want user to prompt to sign-in. How can i do this? Please show me some sample code that can pass sessionID in the url/headers so that it wont prompt for creadentials and will directly show the reports.

Thanks in advance,

Nithin
