hola a todos, tengo el siguiente problema al querer conseguir una conexion usando jndi, me da el siguiente error:

cuando intento obtener la conexión lo hago con el siguiente método:
public Connection getConnection() {
Connection cn=null;
try{
/*Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.enterprise.naming.SerialInitContextFactor y");
env.put(Context.PROVIDER_URL,
"localhost:3306/virtual_shop?user=root&password=root");
Context initialContext = new InitialContext(env);
*/
Context ic = new InitialContext();
DataSource ds;
ds = (DataSource) ic.lookup("jdbc/virtualshop");
cn = ds.getConnection();
}
catch(Exception e){e.printStackTrace();}
return cn;
}
donde jdbc/virtualshop es el nombre JNDI, al connectionpool dentro del glassfish le pase todos los parametros: usuario, password, server, puerto y lo tengo bien configurado ya que al hacerle ping no da ningun problema
no se en si cual sera el problema ??
