Put the result in the same page

Hi,

i have a jsp page very simple, that have a form with a text field and a submit button, above are the code :

As you can see i have a action named "dasaldo" that is the name of my servlet, above are the servlet code :

import java.io.*;
import java.net.*;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import javax.servlet.*;
import javax.servlet.http.*;
/**
*
* @author luis
*/
public class dasaldo extends HttpServlet {
protected void processRequest(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
String sql_query1 = "select campo1 from tabela where campo2 = ? ";
try {
Class.forName("com.ibm.as400.access.AS400JDBCDriver");
Connection connection = DriverManager.getConnection("jdbc:as400:IP_Address/LIB; ,"Admin", "Admin");
PreparedStatement prepared_statement = connection.prepareStatement(sql_query1);
prepared_statement.setString(1, request.getParameter("conta"));
ResultSet rs = prepared_statement.executeQuery();
while(rs.next() ){
System.out.println(rs.getString(1));
}
connection.close();
}catch(Exception ex){
ex.printStackTrace();
}
}
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
processRequest(request, response);
}
public String getServletInfo() {
return "Short description";
}
}

Everything works fone, and when a put the name of client and press submit,
the app print in System.out.println the resultset fine.

the problem is that i want to put the resultSet in the page and not in System.out.println
what can i do to put the result of query in the same JSP that have the text field and the submit button ?
