NoClassDefFoundException in seam-gen generated code !!!

[simplex-software]

Greetings,

After having ran "seam generate-entites" on my db and after having deployed the EAR, I got the following exception in the log file:

2008-01-23 17:16:58,786 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[localhost].[/SimplexCRM]] Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.jboss.seam.servlet.SeamListener

................. etc.

The reason of this exception is displayed further, in the log file:

Caused by: java.lang.NoClassDefFoundError: fr/simplexSoftware/crm/jpaBeans/AccountsAuditId

 ... 139 more

The EAR file contains in its lib directory a jar which contains all the required classes, including the one flagged as missing. The application.xml correctly defines the modules, so I don't understand how is it possible that this exception is raised, given that all the classes are there.

Could anybody help please ?

Many thanks in advance.

Post the application.xml and the output of ls -R on the exploded ear.
