Help with Tomcat 5 and MS Access

Question

Hi
I have a Tomcat 5 running and I want to query to a MS Access. Must I configure the server.xml to allow the connection?
I'm doing the connection in a class, not in JSP:
import java.sql.*;
public class BaseDatos {
String url="jdbc:odbc:sms";
String driver="sun.jdbc.odbc.JdbcOdbcDriver";
Connection con=null;
private Statement statement;
public BaseDatos()
       try{
              Class.forName(driver).newInstance();
   catch (Exception e) {}
public void Conectar()
  try {     
             con = java.sql.DriverManager.getConnection(url);
             statement = con.createStatement();
  catch (java.sql.SQLException e){e.printStackTrace();}
public void Guardar_sms(String prefijoL, String numeroL, String mensajeL, String recibo, String tabla)
     try
           Conectar();
           if (recibo.equals("1")) //si hay recibo eliminamos del texto los car�cteres de recibo
              mensajeL=mensajeL.substring(3,mensajeL.length());     
         statement.executeUpdate("INSERT INTO "+tabla+"(PREFIJO,NUM_MOVIL,TEXTO,RECIBO) VALUES ('"+prefijoL+"','" +numeroL+"','"+mensajeL+"','"+recibo+"')");
     } catch (SQLException e)
           e.printStackTrace();     
     Desconectar();
  public void Guardar_contacto(String nombre, String prefijo,String numero)
     Conectar();     
     ResultSet rs=null;
     try
          rs=statement.executeQuery("Select * from smsagenda where NOMBRE ='"+nombre+"' and NUM_MOVIL = '"+numero+"'");
          if (!rs.next()){System.out.println("no he encontrado el numero de telefono y guardo el nuevo");
          statement.executeUpdate("INSERT INTO smsagenda (NOMBRE,PREFIJO,NUM_MOVIL) VALUES ('"+ nombre+"','"+prefijo+"','"+numero+"')");
     catch(SQLException e)
          e.printStackTrace() ;
     Desconectar();
public void Borrar(int id,String tabla)
     Conectar();
     try
          statement.executeUpdate("DELETE FROM "+tabla+" WHERE ID="+id+"");
     }catch(SQLException e)
          e.printStackTrace() ;
     Desconectar();
public ResultSet leerTabla(String tabla)
     ResultSet rs=null;
     try
          rs=statement.executeQuery("Select * from "+tabla);
     }catch(SQLException e)
          e.printStackTrace() ;
     return rs;
public void Desconectar()
    if (con!=null)
       try
                 con.close();
        }catch (SQLException e){}
}Thanks in advance

Now I have modified the server.xml file in the
TOMCAT_HOME/conf/server.xml................like
this,just a line
/******************************* server.xml
<Context path="/sampleapp" docBase="e:\sampleapp"
debug="0" reloadable="true">
</Context>
/*****************************server.xml***************
********************/You say that your application is under
TOMCAT_HOME/webapps/sampleapp and then you tell
server.xml to look under e:\sampleapp ?? Don't you
find that strange?
you could probably use docBase="/sampleapp"
Also, you NEED to put your classes in packages.Thanks for the information about
