Estoy creando una aplicación para ejecutarse en JBoss utilizando hibernación. Cuando ejecuto la aplicación me sale el siguiente error:

    21:15:55,848 ERROR [org.hibernate.tool.hbm2ddl.SchemaUpdate] (MSC service thread 1-8) HHH000319: Could not get database metadata: java.sql.SQLException: No suitable driver found for jdbc:mysql://localhost:3306/researchprojects

He incluido el controlador mysql en la carpeta WEB-INF / lib y también lo he agregado en la ruta de compilación. No he modificado el archivo standalone.xml ya que incluyo toda la información requerida sobre la conexión a la base de datos en el archivo persistence.xml.

El archivo persistence.xml es así:

<persistence xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="2.0">
  <persistence-unit name="test"  >
  <provider>org.hibernate.ejb.HibernatePersistence</provider>    
    <!-- <jta-data-source>java:jboss/datasources/DefaultDS</jta-data-source>  -->        
    <properties>
      <property name="hibernate.dialect" value="org.hibernate.dialect.MySQLDialect"/>    
      <property name="hibernate.show_sql" value="true"/>   
      <property name="hibernate.max_fetch_depth" value="3"/>
      <property name="hibernate.hbm2ddl.auto" value="update" /> 
      <property name="hibernate.connection.driver_class" value="com.mysql.jdbc.Driver"/>
        <property name="hibernate.connection.url" value="jdbc:mysql://localhost:3306/researchprojects"/>
        <property name="hibernate.connection.username" value="root"/>
       <property name="hibernate.connection.password" value="351984"/>            
    </properties>
  </persistence-unit>
</persistence>

¿Alguien podría darme una pista de cómo resolver este problema? He mirado todas las publicaciones relacionadas antes de la publicación aquí, pero nada me ayudó.
