Caros,
Sou iniciante em EJB3 e estou tentando fazer um exemplo simples: cadastrar um Usuario(id, nome) em um banco de dados mysql. Por favor, caso algum desenvolvedor mais experiente puder me ajudar:
1- No Netbeans 7.2 criei uma Aplicação Enterprise, gerando CadUsuarios-war e CadUsuarios-ejb
2- No CadUsuarios-ejb:
2.1- Uma Unidade de persistência
2.2- Uma Classe de Entidade do Banco de Dados
2.3- Um Bean de Sessão @Local UsuarioSessionBean que apenas da um entityManager.persist(usuario) no método save, que e está definido na interface UsuarioSessionBeanLocal
3- No CadUsuarios-war
3.1- Adicionei o Framework Java Server Faces
3.2- Gerei uma Classe Java UsuarioController:
public class UsuarioController {
@EJB
private UsuarioSessionBean usuarioSB;
private Usuario usuario;
...
public void create(){
try{
usuarioSB.save(usuario);
System.out.println("Usuário cadastrado");
} catch (Exception ex) {
System.out.println("Erro ocorrido");
}
}
3.3- Criei um index.jsp:
...
<h:commandButton action="#{usuarioJSFBean.createSetup()}" label="Criar objeto"/>
<h:panelGrid columns="1">
<h:outputText value="Seu nome:"/>
<h:inputText id="userEmail" value= "#{usuarioJSFBean.usuario.nome}" title="Seu nome" />
</h:panelGrid>
<h:commandButton action="#{usuarioJSFBean.create()}" label="Cadastrar"/>
...
3.4- Configurei o faces-config.xml:
<managed-bean>
<managed-bean-name>usuarioJSFBean</managed-bean-name>
<managed-bean-class>br.com.jsf.UsuarioController</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
</managed-bean>
Implantei a Aplicação Enterprise. Quando rodo o http://localhost:8080/CadUsuarios-war/ ocorre o erro: Um erro ocorreu ao realizar a injeção de recurso no bean gerenciado usuarioJSFBean
com.sun.faces.mgbean.ManagedBeanCreationException: Um erro ocorreu ao realizar a injeção de recurso no bean gerenciado usuarioJSFBean
