My components.xml is in ear/war/WEB-INF. The debug="true" doesn't help because the componenet has not been read. I have changed the source of seam MailSender.java private String sessionJndiName = "java:/Mail"; | | @Create | public void create() throws NamingException | { | if ( getSessionJndiName()==null ) | { | createSession(); | } else { | session = (Session) Naming.getInitialContext().lookup( getSessionJndiName() ); | } | } and now the email is send. This is quite Hack, but I have run out of correct ideas. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4080457#...
