Re: [reverbel-sma] problema com lookup

OLá Alexandre.

Como o seu servlet e seu EJB vão estar executando dentro da mesma
intância de servidor de aplicações, acredito que incluir um
jndi.properties seja desnecessário. Uma outra coisa: você pode usar
"AdministradorDeMatriculasBean/local" ao invés de
"AdministradorDeMatriculasBean/remote" (pois o servlet e o EJB estão
na mesma instância de servidor de aplicações). Nesse caso, você vai
precisar criar também uma interface local. Veja o exemplo em:

http://docs.jboss.org/ejb3/app-server/tutorial/stateless/stateless.html

Se não resolver o problema, por favor volte a escrever. Um abraço!

Olá,

ao executar o seguinte código (dentro de uma servlet rodando no jboss):

AdministradorDeMatriculas adm =


(AdministradorDeMatriculas)
ctx.lookup("AdministradorDeMatriculasBean/remote");

ocorre o seguinte erro:

no JNDIview consta a seguinte informação a respeito do nome que eu
estou fazendo lookup:

 +- AdministradorDeMatriculasBean (class: org.jnp.interfaces.NamingContext)
  |   +- remote (proxy: $Proxy66 implements interface
matriculas.ejb.AdministradorDeMatriculas,interface
org.jboss.ejb3.JBossProxy,interface javax.ejb.EJBObject)


Minha suspeita é de que o problema está no jndi.properties:

java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=localhost

É isso, valeu!
