BPM API fetching Tasks (7.3)

Question

Hi All,
based on this documentation: http://help.sap.com/saphelp_nw73/helpdata/en/79/d505324ef8429489979e43b76b56a9/content.htm i tried to fetch all active tasks for the currently logged in user, but the result is always a empty list. I found the following thread which is nearly facing the same problem: UWL api doesn't seem to see items ,but i dont know how to configure the system alias or if its even the fault of the alias.
Are there any other important steps to execute for using the new BPM API? What could be missing in the configuration?
Best Regards
Michael

Hi,
at the moment my web.xml looks like this (based on http://www.urz.uni-heidelberg.de/saphelp/helpdata/DE/34/96c041a2236a24e10000000a1550b0/frameset.htm):

</web-app>
and my web-j2ee-engine.xml:
<?xml version="1.0" encoding="UTF-8"?>
<web-j2ee-engine xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:noNamespaceSchemaLocation="web-j2ee-engine.xsd">

     <login-module-configuration>
          <login-module-stack>

                    <flag>SUFFICIENT</flag>
               </login-module>
          </login-module-stack>
     </login-module-configuration>
</web-j2ee-engine>
If i call my index.jsp i get a little popup window where i can put my username and password in, but then it gets stuck. The http-request is loading endless and on serverside the responsible thread got a infinite loop - resulting in a server restart.
Can someone provide me a working example of these xml files?
