Open Source Document Management System | OpenKM

Guys, i have an error in my openkm while using openkm. when i login to the openkm the error is "OKM-015024 (findUserTaskInstances) : Database Error...." i attach the error,

what should i do?
i'm using Openkm 6.3.0 Community, Jboss Developer Studio 8.1.0 GA, jBPM jPDL 3.3.1.GA

Please i need advice from you all..Thank you

First I suggest go for http://sourceforge.net/projects/openkmportabledev/ ( OpenKM portable edition ).
I think there's a problem with workflows and HSQL database, I suggest you configure for MySQL database, read here http://wiki.openkm.com/index.php/MySQL_-_OpenKM_6.2 ( on production you must go for it )

Thanks for the reply.. the problem is solved, but i have a new error again.

"error communicating with the server (setTaskInstancesValues)"..

i want to get the Input Values ("Superiors") then i assign that values as actor in next task. is that possible? And what should i do.. I'm newbie in Java and jbpm..

below i attached the .par project..

Please do not merge several questions on same topic, add another post for it. Thanks
