Hello all.
In a jsp application, I´m trying to conect to the application´s db (MySQL) by:
// jsp file
<%
YYY.Atividade atv;
atv = new YYY.Atividade();
atv.criaConexaoBD();
%>
// bean
public void criaConexaoBD()throws ClassNotFoundException, IllegalAccessException,InstantiationException, SQLException
{
String driver = "com.mysql.jdbc.Driver";
String url = "jdbc:mysql://130.1.1.130/mdb1";
Class.forName(driver).newInstance();
this.conexaoBanco = DriverManager.getConnection(url, "root", "");
this.v_statement = this.conexaoBanco.createStatement();
}

I´m getting this server (Tomcat v. 5.0) message:

ERRO :java.sql.SQLException: Invalid authorization specification, message from server: "Access denied for user: 'root'@'egdesenvolv.globoprdom.com.br' (Using password: NO)" .

Even using a password or changing the user i´m getting the same trouble...I know that if i use
url= "jdbc:mysql://localhost/mdb1";
the connection work´s...

Does somebody know´s what´s wrong?
Thank´s for your attention,
Rafael.
