Exemplo completo com EJB 3

Criando o Entity Bean

package teste; import java.io.Serializable; import javax.persistence.Entity; import javax.persistence.Id; @Entity public class Cliente implements Serializable {    private static final long serialVersionUID = 1L;    @Id    private int codigo;    private String nome;    private String endereco;    private String telefone;    public String toString() {       return String             .format("%20s%20s%20s%20s", codigo, nome, endereco, telefone);    }    public int getCodigo() {       return codigo;    }    public void setCodigo(int codigo) {       this.codigo = codigo;    }    public String getNome() {       return nome;    }    public void setNome(String nome) {       this.nome = nome;    }    public String getEndereco() {       return endereco;    }    public void setEndereco(String endereco) {       this.endereco = endereco;    }    public String getTelefone() {       return telefone;    }    public void setTelefone(String telefone) {       this.telefone = telefone;    } }

Criando o Session Bean
Interface Remota

package teste; import java.util.List; import javax.ejb.Remote; @Remote public interface ClienteBean {    void inserir(Cliente cliente);    List<Cliente> listar(); }

Implementação

package teste; import java.util.List; import javax.ejb.Stateless; import javax.ejb.TransactionAttribute; import javax.ejb.TransactionAttributeType; import javax.persistence.EntityManager; import javax.persistence.PersistenceContext; import javax.persistence.Query; @Stateless(name = "cli", mappedName = "ejb/ClienteBean") @TransactionAttribute(TransactionAttributeType.REQUIRES_NEW) public class ClienteBeanImpl implements ClienteBean {    @PersistenceContext(unitName = "bean1")    private EntityManager em;    public void inserir(Cliente cliente) {       em.persist(cliente);    }    @TransactionAttribute(TransactionAttributeType.NEVER)    public List<Cliente> listar() {       Query query = em.createQuery("select c from Cliente c");       return query.getResultList();    } }

Cliente do EJB

import java.util.List; import java.util.Properties; import javax.naming.InitialContext; import javax.naming.NamingException; import teste.Cliente; import teste.ClienteBean; public class Consumo {    public static void main(String[] args) {       if (args.length == 0) {          System.out.println("Qtd de parametros incorreta");          System.exit(0);       }       int codigo = new Integer(args[0]);       try {          Properties props = new Properties();          props.setProperty("java.naming.factory.initial",                "com.sun.enterprise.naming.SerialInitContextFactory");          props.setProperty("java.naming.factory.url.pkgs",                "com.sun.enterprise.naming");          props.setProperty("java.naming.factory.state",                "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");          // optional. Defaults to localhost. Only needed if web server is          // running          // on a different host than the appserver          props.setProperty("org.omg.CORBA.ORBInitialHost", "10.0.0.100");          // optional. Defaults to 3700. Only needed if target orb port is not          // 3700.          props.setProperty("org.omg.CORBA.ORBInitialPort", "3700");          InitialContext ctx = new InitialContext(props);          ClienteBean bean = (ClienteBean) ctx.lookup("ejb/ClienteBean");          Cliente cliente = new Cliente();          cliente.setCodigo(codigo);          cliente.setNome("antonio");          cliente.setEndereco("Rua 2");          cliente.setTelefone("6363-5252");          bean.inserir(cliente);          List<Cliente> lista = bean.listar();          for (Cliente c : lista) {             System.out.println(c);          }       } catch (NamingException e) {          e.printStackTrace();       }    } }

Relação de .jar
Arquivos .jar necessários:

No ejb:

• appserv-rt.jar
• javaee.jar

No cliente:

• appserv-rt.jar
• javaee.jar
• appserv-deployment-client.jar

Iniciando ao JavaDB (Derby)

• Passo 1

ligue o servidor com o comando: java -jar derbynet.jar start

• Passo 2

dados para conexão:
url: jdbc:derby://localhost:1527/exemplojpa;create=true
driver: org.apache.derby.jdbc.ClientDriver

Configuração do TopLink para funcionamento com datasource no tomcat:

import oracle.toplink.essentials.jndi.JNDIConnector; import oracle.toplink.essentials.sessions.Session; import oracle.toplink.essentials.tools.sessionconfiguration.SessionCustomizer; public class ToplinkSessionCustomizer implements SessionCustomizer {   public void customize(Session session) throws Exception {     JNDIConnector connector = (JNDIConnector) session.getLogin()         .getConnector();     connector.setLookupType(JNDIConnector.STRING_LOOKUP);   } }

linha a ser acrescientada nas properties:

<property name="toplink.session.customizer" value="pacote.ToplinkSessionCustomizer"/>
