Human worklist API TaskQueryService-querying tasks and updating outcome from J2ee application

In my recent project I had a requirement where the HumanTask Worklist API had to be invoked from a J2ee application to fetch all the assigned tasks for a particular user. So we had given them the TaskQuery web service to list all the assigned tasks for particular user. I am listing the input and output.

Querying the task list

WSDL for the Task Query Service: http://<soa_host>:><port>/integration/services/TaskQueryService/TaskQueryService?WSDL

Method:  queryTasks

Input
