Thank you, it is a little bit clearer now.=20
One thing I don't understand however is this:
In
http://turbine.apache.org/turbine/turbine-2.3.3/services/torque-security-=
ser
vice.html there is an exapmple of an extended user class. It looks lie =
this:
public class ExtendedUser extends TorqueUser
{
  public ExtendedUser()
  {
      super();
  }

  public ExtendedUser(Persistent obj)
  {
      super(obj);
  }

  public String getPhone()
  {....

How is this class created? Do I write it myself or is it created via the =
ant
script? The thing that confuses me is that it extends TorqueUser and not
BaseExtendedUser. How do I make that connection?

Hi Ludwig,

so not use the TurbineUser Directly. Please use TurbineSecurity Object =
for
that.

Please read=20

http://turbine.apache.org/turbine/turbine-2.3.3/apidocs/org/apache/turbin=
e/s
ervices/security/TurbineSecurity.html
http://turbine.apache.org/turbine/turbine-2.3.3/services/torque-security-=
ser
vice.html

It will make everything a lot clearer

Kind regards

Juergen
