REM: i have put the Struts libraries at the top of the EAR because Jboss
could nt load these.

I could see in the forum that there are 2 separate ClassLoaders the
first for EJBs and the second for WebApp. In the following code (which
throws the ClassNoFoundError) , Jboss seems to use the bad ClassLoader
(EJBClassLoader ?) after EJB calls :-(

My Code:

EJBVacationAskFacadeHome home = (EJBVacationAskFacadeHome)
ServiceLocator.getLocator().getHome(EJBVacationAskFacadeHome.JNDI_NAME);

EJBVacationAskFacade facade = home.create();
facade.createNewAsk(VacationAskLineWrapper.getLines(form.getAsks()),
(....)

//The EJBClassLoader is Still used!!!!!!
MailHelper mailer = new MailHelper(props,
Config.getInstance().getProperty(ConfigKeys.MAIL_ASKS_QUERY_BODY_ADV));
// ---> EXCEPTION :-(
mailer.setToAddress(form.getEmail());
mailer.send();

I have the same exception when i m trying to deploy separately the
webapp and ejb in the Jboss-Tomcat server.
Actually, I am obliged to use separately Tomcat and Jboss.
if you have a sample of EAR with Struts Webapp and EJB, I would be very
interested to see that :-D
Thanks for your help and sorry for my english
