Note that there is also a user that is called SYSTEM. These are not the same. Seems that in your example you use the user SYSTEM and you are not running as SYSTEM. In the answer above you can choose between the methods executeAsSystem and executeAsSystemUser.</p>Reto WeissThu, 23 Oct 2014 20:19:40 -0400https://answers.axonivy.com/questions/1020/permission-denied-needs-permission-system-but-the-session-is-system/1026https://answers.axonivy.com/questions/1020/permission-denied-needs-permission-system-but-the-session-is-system#1025<p>Yes this approach is working. But the next call doesn't: task.writeInternalStartProcessData(processData); (NullPointerException somewhere inside writeInternalStartProcessData) Seems that I cant manually save the Task data..</p>HaraldWeberThu, 23 Oct 2014 15:32:33 -0400https://answers.axonivy.com/questions/1020/permission-denied-needs-permission-system-but-the-session-is-system#1025https://answers.axonivy.com/questions/1020/permission-denied-needs-permission-system-but-the-session-is-system/1024<p>Does it work if you use the SecurityManager approach to call the protected API?</p> <p><a href="http://answers.axonivy.com/questions/744/how-can-i-disable-xpert-ivy-security-permission-checks/746">http://answers.axonivy.com/questions/744/how-can-i-disable-xpert-ivy-security-permission-checks/746</a></p>Reguel WermelingerThu, 23 Oct 2014 15:14:12 -0400https://answers.axonivy.com/questions/1020/permission-denied-needs-permission-system-but-the-session-is-system/1024
