Fwd: [reverbel-sma] problema com lookup

["Alexandre Freire" <chegado@xxxxxxxxx>]

Sem o jndi.properties ocorre o seguinte erro (tanto na chamada à
interface local quanto na remota)

11:37:53,859 ERROR [[Controller]] Servlet.service() for servlet

No JNDIview consta:

+- AdministradorDeMatriculasBean (class: org.jnp.interfaces.NamingContext)
 |   +- local (proxy: $Proxy68 implements interface
matriculas.ejb.AdministradorDeMatriculasLocal,interface
org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBLocalObject)
 |   +- remote (proxy: $Proxy67 implements interface
matriculas.ejb.AdministradorDeMatriculasRemote,interface
org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)


só consigo chamar a interface remota de fora do jboss.

Valeu Ivan!
