Exception if bean does not implement business interface

Hi, i'm new to seam. I'm getting an exception if I do not make my stateless beans implement a business interface annotated with @Local. Im getting this error when deploying:

java.lang.RuntimeException: bean class has no local, webservice, or remote interfaces defined and does not implement at least one business interface: BuscadorLocalidad
	at org.jboss.ejb3.ProxyFactoryHelper.getLocalInterfaces(ProxyFactoryHelper.java:115)
	at org.jboss.ejb3.interceptor.EJB3InterceptorsFactory.getBusinessInterfaces(EJB3InterceptorsFactory.java:172)
	at org.jboss.ejb3.interceptor.EJB3InterceptorsFactory.isBusinessMethod(EJB3InterceptorsFactory.java:122)
	at org.jboss.ejb3.interceptor.EJB3InterceptorsFactory.createPerJoinpoint(EJB3InterceptorsFactory.java:98)
	... 108 more

The exception message is very clear, and everything works fine if I make them implement an annotated business interface. My question is, because I saw some examples that do not use @Local and work allright (for example, seambay, bean AuctionAction). What am i missing?

Thanks for your time, Juan Ignacio
