Hi Markus ,

I think that it has nothing to do with flow but I already received such a message when using a component that I created and that has to use a datasource.

This datasource has to be defined in cocoon.xconf and if he can not open it you will get an error

hope it could help

Laurent

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. How
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 [org.apache.avalon.excalibur.datasource.DataSourceComponent])
(Key='org.apache.avalon.excalibur.datasource.DataSourceComponent') (key
[org.apache.avalon.excalibur.datasource.DataSourceComponent])


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.ROLE);
                                 DataSourceComponent datasource =
(DataSourceComponent)selector.select(this.poolId);
                                 Connection con = datasource.getConnection();
                                 ...
                }
...


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
