implementando EJB sobre JBoss 7.1

Question

Estoy implementando una aplicación EJB de estilo helloworld realmente simple. Al hacerlo me sale ...

Parece que tengo que añadir un include en algún lugar, mi código es muy simple ...

package server; 

import java.io.IOException; 
import java.io.PrintWriter; 

import javax.ejb.EJB; 
import javax.persistence.EntityManagerFactory; 
import javax.persistence.PersistenceUnit; 
import javax.servlet.ServletException; 
import javax.servlet.annotation.WebServlet; 
import javax.servlet.http.HttpServlet; 
import javax.servlet.http.HttpServletRequest; 
import javax.servlet.http.HttpServletResponse; 

import model.MyUser; 

/** 
* Servlet implementation class HelloServlet 
*/ 
@WebServlet("/HelloServlet") 
public class HelloServlet extends HttpServlet { 
    private static final long serialVersionUID = 1L; 


    @EJB HelloBean bean; 
    @PersistenceUnit 
    EntityManagerFactory emF; 
    /** 
    * @see HttpServlet#HttpServlet() 
    */ 
    public HelloServlet() { 
     super(); 
     // TODO Auto-generated constructor stub 
    } 

    /** 
    * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response) 
    */ 
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     PrintWriter out = response.getWriter(); 
     out.print("<html><body>"); 
     MyUser user = (MyUser)emF.createEntityManager().createQuery("select * from myuser").getResultList().get(0); 
     out.println("Username = " + user.getName()); 
     out.print("</body></html>"); 
    } 

    /** 
    * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response) 
    */ 
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { 
     // TODO Auto-generated method stub 
    } 

} 

Persistance.xml se muestra a continuación ...

<module xmlns="urn:jboss:module:1.0" name="com.mysql.jdbc"> 
    <resources> 
    <resource-root path="mysql-connector-java-5.1.18-bin.jar"/> 
    </resources> 
    <dependencies> 
    <module name="javax.api"/> 
    </dependencies> 
</module> 

Standalone.xml tiene la siguiente entrada ...

<subsystem xmlns="urn:jboss:domain:datasources:1.0"> 
      <datasources> 
      <datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true"> 
       <connection-url>jdbc:mysql://localhost:3306/ejbdb</connection-url> 
       <driver>com.mysql</driver> 
       <security> 
        <user-name>root</user-name> 
        <password>root</password> 
       </security> 
      </datasource> 
    <drivers> 
      <driver name="com.mysql" module="com.mysql.jdbc"> <xa-datasource-class>com.mysql.jdbc.Driver</xa-datasource-class> </driver> 
     </drivers> 
     </datasources> 
     </subsystem> 

En mi proyecto, tienen el tarro de MySQL en /WebContent/META-INF/services/mysql-connector-java-5.1.18-bin. jar

¿Alguien tiene alguna idea?

Gracias!

EDIT: Probado ...

<datasource jndi-name="java:jboss/datasources/EjbMySql" pool-name="EjbMySql" enabled="true" use-java-context="true"> 
        <connection-url>jdbc:mysql://localhost:3306/ejbdb</connection-url> 
        <driver>com.mysql.jdbc.Driver</driver> 
        <security> 
         <user-name>root</user-name> 
         <password>root</password> 
        </security> 

se vuelva con el mismo error.

Answer 1

En <JBOSS_HOME>/standalone/configuration/standalone.xml busque la etiqueta <subsystem xmlns="urn:jboss:domain:datasources:1.0"> y agregue lo siguiente dentro del <datasources> elemento:

<datasources> 
    <datasource jndi-name="java:jboss/datasources/MysqlDS" pool-name="MysqlDS" enabled="true" use-java-context="true"> 
     <connection-url>jdbc:mysql://localhost:3306/DATABASE_NAME</connection-url> 
     <driver>com.mysql</driver> 
     <security> 
      <user-name>USERNAME</user-name> 
      <password>PASSWORD</password> 
     </security> 
    </datasource> 
    <drivers> 
     <driver name="com.mysql" module="com.mysql"> 
      <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> 
     </driver> 
    </drivers> 
</datasources> 

Reemplace DATABASE_NAME, USERNAME y PASSWORD de forma automática.

Dentro del elemento <drivers> agregar lo siguiente:.

<driver name="com.mysql" module="com.mysql"> 
    <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> 
</driver> 

Ahora, vaya a <JBOSS_HOME>/modules y crear la ruta com/mysql/main poner el tarro del conductor allí (por ejemplo, mysql-connector-java-5.1.18-bin.jar) y crear el archivo module.xml con el siguiente contenido:

<module xmlns="urn:jboss:module:1.1" name="com.mysql"> 

    <resources> 
     <resource-root path="mysql-connector-java-5.1.18-bin.jar"/> 
     <!-- Insert resources here --> 
    </resources> 
    <dependencies> 
     <module name="javax.api"/> 
     <module name="javax.transaction.api"/> 
     <module name="javax.servlet.api" optional="true"/> 
    </dependencies> 
</module> 

Que debe hacer el truco.

Answer 2

En JBoss 7, se cambiaron varios detalles de configuración para crear una fuente de datos e instalar un controlador JDBC. Eche un vistazo a esta migración guide, en las secciones "Definir la fuente de datos" e "Instalar el controlador JDBC".

Answer 3

creo que es necesario asociar el origen de datos en standalone.xml con el conductor del módulo, como en el siguiente ejemplo (tomado de here:

 <datasources> 
      <datasource jndi-name="java:jboss/datasources/ExampleDS" enabled="true" use-java-context="true" pool-name="H2DS"> 
       <connection-url>jdbc:h2:mem:test;DB_CLOSE_DELAY=-1</connection-url> 
       <driver>h2</driver> 
       <pool></pool> 
       <security> 
        <user-name>sa</user-name> 
        <password>sa</password> 
       </security> 
       <validation></validation> 
       <timeout></timeout> 
       <statement></statement> 
      </datasource> 
      <drivers> 
       <driver name="h2" module="com.h2database.h2"> 
        <xa-datasource-class>org.h2.jdbcx.JdbcDataSource</xa-datasource-class> 
       </driver> 
       <driver name="mysql" module="com.mysql.jdbc"> <xa-datasource-class>com.mysql.jdbc.jdbc2.optional.MysqlXADataSource</xa-datasource-class> </driver> 
      </drivers> 
     </datasources> 

El elemento conductor en fuentes de datos en el presente documento hace referencia a una definición de controlador el elemento del controlador, que en sí mismo hace referencia al módulo que definió y las clases. Así es como lo uso, y funciona para mí en JBoss 7.1.

Answer 4

Es la versión del controlador. Cambiar por una nueva versión. ¡Crea, es solo eso! Cambié el controlador mysql-connector-java-5.0.4-bin.jar a mysql-connector-java-5.1.25-bin.jar, entonces el problema está resuelto.
