Problem with Java API, to develope the custom worklist application

541951Sep 27 2012 — edited Feb 26 2020
Hi,

I have been trying to develop custom worklist application. I am facing the following exception while trying to access the "queryTasks" operation, from my custom web application.

Please help me to solve this error.
