        Subject:        [flow] cocoon.createObject() problem

Hi Friends!

I've written a java class "User" which stores user data selecting from a
database. I want to use the cocoon datasource defined in the cocoon.xconf
and the logging for it and I need to use the class within my flowscript. 
can I manage this?

Searching a while I found the cocoon.createObject() flow function that may
help me but I don't understand how to use it. I tried something like this

var user = cocoon.createObject("some.package.User");

which returns the User object. but calling the function

user.load("username", "password"); // (see below)

throws the following exception:

org.apache.avalon.framework.component.ComponentException: Could not find
component (key 
(Key='org.apache.avalon.excalibur.datasource.DataSourceComponent') (key

The User class looks like the following:

public class User implements LogEnabled, Composable {
                 public boolean load(String authUsername, String 
authPassword) {
                                 ComponentSelector selector = 
(ComponentSelector) manager.lookup
                                 DataSourceComponent datasource =
                                 Connection con = 

What am I doing wrong? Can somebody help me please? I really need it. I'm
using the current CVS head and SDK 1.4.2.

Thanks a lot!

Greetings, Markus
