[Jeison Pereira]

Hi, all!!

I trying very times. but it same problem. Project EJB communication other project web (I created project enterprise application in netbeans) with Glassfish Server. see in below.
You can to help me. tips or fixed the resolve this problem.

Project EJB:

Local

@Local
public interface NomeBeanLocal {
     public void addNome(String nome);
     public ArrayList<String> getListNome();
     public int count();
}

Bean do stateless

@Stateless
public class NomeBean implements NomeBeanLocal {

    private final static ArrayList<String> nomes;

    @PostConstruct
    public void init() {
        nomes = new ArrayList<String>();
        nomes.add("Ingrid Cardoso");
        nomes.add("Suellen Floriano");
    }

    @Override
    public void addNome(String nome) {
        nomes.add(nome);
    }

    @Override
    public ArrayList<String> getListNome() {
        return nomes;
    }

    @Override
    public int count() {
        return nomes.size();
    }

}

Project Web

Bean

@Named(value = "nomesBean")
@SessionScoped
public class NomesBean implements Serializable {

    @EJB
    private NomeBeanLocal nomeBean;
    private String nome;

    /**
     * Creates a new instance of NomesBean
     */
    public NomesBean() {
    }

    public String getNome() {
        return nome;
    }

    public void setNome(String nome) {
        this.nome = nome;
    }

    public ArrayList<String> getListNomes() {
        return nomeBean.getListNome();
    }

    public String salvaNome(){
        nomeBean.addNome(this.nome);
        return "index.xhtml";
    }

}

Index page

<h:body>
        <h:form>
            <h:panelGrid columns="2"> 
                <h:outputLabel value="Seu nome: " for="labelNome"/>
                <h:inputText value="#{nomesBean.nome}" id="labelNome" />
                <h:commandButton action="#{nomesBean.salvaNome()}"  value="Salva seu nome"/>
            </h:panelGrid>
        </h:form>
        <h:dataTable value="#{nomesBean.listNomes}" var="nome">
            <h:column>
                <f:facet name="header">Nomes</f:facet>
                    #{nome}
            </h:column>
        </h:dataTable>
    </h:body>

Welcome to the Ranch.

Were you able to figure out what might went wrong?

I suspect you the web project can't find the EJB from the JNDI. Are the EJBs deployed? Is the JNDI path known/correct? May want to specify the "name" attribute for the EJB annotation:
@EJB(name="myEJB")

This way this will create a reference to JNDI as "java:comp/env/MyEJB" instead of "java:/comp/env/somepackage/MyClass/myField" or something hard to decipher.

Another thing I noticed is @Named. Since you seem to be using JSF, should a @ManagedBean be more appropriate?
