Fala pessoal tudo bom?

Estou com o seguinteproblema , eu tenho um módulo ejb que eu queria fazer um crud,
Porem utilizando um DataSource e o EntityManager junto com JPA

Comecei adesenvolver a aplicação desde modo:

InterfaceLocal e Implementação

package br.com.crud.service;

import javax.ejb.Local;

import br.com.crud.model.Employee;



/**
 * @author Gabriel Castilho
 *
 */
@Local
public interface EmployeeServiceLocal {
	
	public void change(Employee e);

	public void delete(Employee e);

	public void save(Employee e);

}

package br.com.crud.service;

import javax.ejb.Stateless;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import br.com.crud.model.Employee;

/**
 * @author Gabriel Castilho
 */

@Stateless
public class EmployeeServiceLocalImpl implements EmployeeServiceLocal{

	@PersistenceContext
	private EntityManager em;
	
	public void change(Employee e){
			
	}
	public void delete(Employee e){
		
	}
	public void save(Employee e){

	}
	

}

Eu tenho um persistence.xml, MySQL-ds.xml no ejbModule

MySQL-ds.xml

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;datasources&gt;
  &lt;local-tx-datasource&gt;
    &lt;jndi-name&gt;mysqlDS&lt;/jndi-name&gt;
    &lt;connection-url&gt;jdbc:mysql://localhost:3306/learning&lt;/connection-url&gt;
    &lt;driver-class&gt;com.mysql.jdbc.Driver&lt;/driver-class&gt;
    &lt;user-name&gt;root&lt;/user-name&gt;
    &lt;password&gt;root&lt;/password&gt;
    &lt;exception-sorter-class-name&gt;org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter&lt;/exception-sorter-class-name&gt;
    &lt;metadata&gt;
       &lt;type-mapping&gt;mySQL&lt;/type-mapping&gt;
    &lt;/metadata&gt;
  &lt;/local-tx-datasource&gt;
&lt;/datasources&gt;

persistence.xml

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"&gt;
    &lt;persistence-unit name="myPersistence"&gt;
    &lt;provider&gt;org.hibernate.ejb.HibernatePersistence&lt;/provider&gt;
        &lt;properties&gt;
            &lt;property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect" /&gt;
            &lt;property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/learning" /&gt;
            &lt;property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver" /&gt;
            &lt;property name="hibernate.connection.password" value="root" /&gt;
            &lt;property name="hibernate.connection.username" value="root" /&gt;
            &lt;property name="hibernate.hbm2ddl.auto" value="create-drop" /&gt;
        &lt;/properties&gt;
	&lt;/persistence-unit&gt;
&lt;/persistence&gt;

My POJO:

package br.com.crud.model;

import javax.persistence.Entity;
import javax.persistence.Id;

/**
 * @author Gabriel Castilho
 * 
 */
@Entity
public class Employee {

	@Id
	private Long id;

	private String name;

	private String mail;
	
	
	// Getters and Setters
	
}

Me vem a seguinte mensagem quando eu subo o ejb.

ObjectName: jboss.j2ee:service=EJB3,module=crud-ejb.jar
  State: FAILED
  Reason: java.lang.RuntimeException: Illegal @PersistenceUnit on private javax.persistence.EntityManager br.com.crud.service.EmployeeServiceLocalImpl.em :There is no default persistence unit in this deployment.

Por favor alguem pode me ajudar?

Obrigado

Não sou muito bom em EJBS mas acho que está faltando isso.

Espero ter ajudado.

Valeu Pessoal

Meu EJB agora não está subindo estranho… vou dar uma olhada

breno500as 27 de fev. de 2010

Qual erro está dando agora?

Abraços…

GabrielCardelli 27 de fev. de 2010

Mudei o persistence.xml para isto:

&lt;?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot;?&gt;
&lt;persistence version="1.0" xmlns="http://java.sun.com/xml/ns/persistence"&gt;
    &lt;persistence-unit name="myPersistence"&gt;
        &lt;jta-data-source&gt;mysqlDS&lt;/jta-data-source&gt;
	&lt;/persistence-unit&gt;
&lt;/persistence&gt;

agora estoou tentando pegar o EntityManager com

@PersistenceContext(unitName="myPersistence")
	private EntityManager entityManager;

e no final das contas o final do log do jboss é:

19:54:29,614 ERROR [URLDeploymentScanner] Incomplete Deployment listing:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:jar=crud-ejb.jar,name=EmployeeServiceLocalImpl,service=EJB3
  State: NOTYETINSTALLED
  I Depend On:
    persistence.units:unitName=myPersistence

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:unitName=myPersistence
  State: NOTYETINSTALLED
  Depends On Me:
    jboss.j2ee:jar=crud-ejb.jar,name=EmployeeServiceLocalImpl,service=EJB3

e o ejb não sobe =/

pode dar um help?

Vou fazer duas perguntas bobas mas não custa conferir:

1 - Seu arquivo MySQL-ds.xml está no diretório /server/default/deploy do seu jboss ?
2 - Seu driver de comunicação com o banco de dados(mysql-connector.jar) está no diretório /server/default/lib ?

Abraços…

GabrielCardelli 27 de fev. de 2010

Está tudo no meu projeto dentro do eclipse o MySQL-ds na raiz, e o jar no classpath.

Então faz um teste colocando estes artefatos nos diretórios que te falei para ver se continua com o mesmo erro ou não…

Abraços…

GabrielCardelli 28 de fev. de 2010

mesmo erro =/

breno500as 28 de fev. de 2010

Bom, vc vai ter que ir fazendo mais testes,erros assim são meio chatos de encontrar…

Lá no seu persistence.xml altere a tag:

para:

GabrielCardelli 28 de fev. de 2010

vou fazendo uns testes aqui.

Sò que pintou uma duvida o @PersistenceContext no código que tem nesse tópico:

http://www.guj.com.br/posts/list/75823.java

E os outros que ja vi não configuram nenhum atributo e funcionanm por que devo configurar?

E em que momento eu mapeio minha classe?

Abraço.

breno500as 28 de fev. de 2010

A anotação @PersistenceContext não necessita de ter um atributo unitName desde que exista apenas uma unidade de persistência no persistence.xml … Por isso acho que vc tbm deve dar uma conferida no build do seu ejb.jar para ver se não esta fazendo mais de uma vez, limpar arquivos temp no container e faça tbm a alteração que eu falei na tag …
