Hallo Johannes,
Yes. They are both in the same directory WEB-INF/classes/hib.
Here is the source code for both file.

public interface PersistenceFactory extends Component {
String ROLE = PersistenceFactory.class.getName();
public net.sf.hibernate.Session createSession();
}
*****************************************************************
Aditional Notes:
- i used jdk1.5 to compile both classes without problem
- i use tomcat 5.5 as container
- cocoon version is 2.1.7
- hibernate version 2.1.8
Thanks is advance,
CarlosN.
ps: shouldn't we do PersistenceFactory.class.getName(); in other way??

Hi Carlos !
You should not need to import the class explicitly when
addressing it via packages.
Another question, though: Do you also have the "HibernateFactory"
class in WEB-INF/classes/hib ?
If so, please post the source codes of both to have a look.
Greetings,
Johannes

hi mike,
that's a good point. i just tried it with the same result. Yes i restarted
tomcat before doing it...

hi carlos,
did you made an import like this
"importClass(Packages.ch.bfh.hti.elquerito.User);" in your flowscript
file?

Mike

Hello!
I'm using cocoon 2.1.7 on tomcat 5.5 and in my
flowscript when i do:
cocoon.getComponent(Packages.hib.PersistenceFactory.ROLE)
i always get this exception:
java.lang.NoClassDefFoundError: hib/PersistenceFactory$1 .
This PersistenceFactory class is in
\Web-inf\classes\hib\
and the role is declared on
\Web-inf\cocoon.xconf
as
<component class="hib.HibernateFactory" role="hib.PersistenceFactory"/>
What can be the problem here??
The PersistenceFactory is an interface class and Role is a string of this
type:
String ROLE = PersistenceFactory.class.getName();
