I'm trying to connect to SQL Server using JSP. But the connection is not made.

Connection Class:

package DAO;

import java.sql.*;
public class Conexao {




public static Connection conectar() {


try {
Class.forName("net.sourceforge.jtds.jdbc.Driver");
Connection con = DriverManager
.getConnection(
"jdbc:jtds:sqlserver://127.0.0.1:1433;DatabaseName=minhadb;namedPipe=false",
"user", "123456");
System.out.println("Conexao ok");
return con;


} catch (ClassNotFoundException e) {
e.printStackTrace();
return null;


} catch (SQLException e) {


System.out.println(e.getErrorCode());
System.out.println(e.getMessage());
e.printStackTrace();
return null;
} catch (Exception e) {


e.printStackTrace();
return null;
}


}


}

Index.jsp

<%@ page language="java" import="java.sql.*, DAO.Conexao" %>
<html>
<head>
<title>
Aprendendo JSP
</title>
</head>
<body>
<%


Connection con = Conexao.conectar();


if( con != null){
out.println("Sucesso");


}
%> 


</body>
</html>

Try this, using the microsoft driver

String usuario = "seuUsuario";
String senha = "suaSenha";
String url = "jdbc:sqlserver://seuHost:1433;databaseName=seuBanco" +
                       ";user=" + usuario + ";password=" + senha + ";";
try {
    Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
    Connection conexao = DriverManager.getConnection(url);
} catch (ClassNotFoundException e) {
    // Erro caso o driver JDBC não foi instalado
    e.printStackTrace();
} catch (SQLException e) {
    // Erro caso haja problemas para se conectar ao banco de dados
    e.printStackTrace();
}

Or if you want to try again with jtds

String url = "jdbc:jtds:sqlserver://seuHost:1433/seuBanco";
String usuario = "seuUsuario";
String senha = "suaSenha";
try {
    Class.forName("net.sourceforge.jtds.jdbc.Driver");
    Connection conexao = DriverManager.getConnection(url, usuario, senha);
} catch (ClassNotFoundException e) {
    // Erro caso o driver JDBC não foi instalado
    e.printStackTrace();
} catch (SQLException e) {
    // Erro caso haja problemas para se conectar ao banco de dados
    e.printStackTrace();
}
