I did a mistake and in components.xml I put
<property name="jndiPattern">">wannabet/#{ejbName}/local
instead of
wannabet/#{ejbName}/local
while I access main.xhtml I got this
exception:org.jboss.seam.InstantiationException: Could not instantiate Seam component: login . . Caused by: javax.naming.NameNotFoundException: ">wannabet not bound . .
sorry I found the problem - i didn't do F5
