Jose,
Hi, your DI annotations on your SSB look fine. You should not need
any glassfish specific descriptors in sun-ejb-jar.xml or sun-web.xml
From your exception it looks like the catalina-based web container does
not have a reference to your EJB on WAR deploy. What kind of client are
you using to access your SSB - I assume you are using @EJB injection on
a servlet or something similar for the ejb abstract or interface
class. Do you have a classpath reference to your ejb project jar from
your PruebaWEB war project jar?
thank you
Michael O'Brien
