Bean não encontrado (Servlet + EJB + JBoss)

Programação Java
#1

Pessoal,

Eu acho que abri o meu problema na seção errada no post anterior: http://www.guj.com.br/java/302958-erro-ao-acessar-servlet-ejb–jboss
O meu servidor está subindo corretamente, sem nenhum problema.
Porém ao acessar o meu Servlet e efetuar uma busca do meu Bean remoto, apresenta a seguinte erro:

E meu ServletController.java

[code]
public class ServletController extends HttpServlet {

private static final long serialVersionUID = 1L;

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	doPost(request, response);
}

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
	try{
		request.setAttribute("grettings", getClientesModel().sayHello());
		request.getRequestDispatcher("listaClientes.jsp").forward(request, response);
	}catch(Exception e){
		e.printStackTrace();
	}
}

private Clientes getClientesModel() throws Exception {
	InitialContext ctx = new InitialContext();
	
	return (Clientes) ctx.lookup("ClientesBean/remote");

}

}[/code]

O meu ClientesBean.class já está com @Stateless na classe e implementando a interface CLientes onde o mesmo define o acesso como @Remote

Consegui resolver o problema.
Visualizei em um fórum americano uma possível solução e naveguei até a documentação do EJB3 no JBoss: http://docs.jboss.org/ejb3/app-server/tutorial/ear/ear.html

Eu estava fazendo o lookup da seguinte forma:

InitialContext ctx = new InitialContext(); return (Clientes) ctx.lookup("ClientesBean/remote");

Porém de acordo com a documentação, deve ser dessa forma:

InitialContext ctx = new InitialContext(); return (Clientes) ctx.lookup("ClientesEAR/ClientesBean/remote");

Padrão:
EARNAME/EJBNAME/local para interfaces Local e EARNAME/EJBNAME/remote para interfaces Remote
