Implementing Database codes FAIL /error in parsing data into jsp page

Question

Hi there,
I have this problem trying to build a portal application. I am using the JSPDynPage, jsp page and a bean to build a page.
I have this problem parsing data from JSPDynPage to the beans and to the jsp page.
I tested out the connection between the beans and the jsp page. There is no error parsing information from the beans to the jsp page.
So i tried to test out the codes for the database from the beans.
Will this work? Because it does not display the results i want.
I need an Solution asap to find out wad is wrong also also the correct codes to the database.
public String db(){
try {
             InitialContext iC = new InitialContext();
             DataSource dataSource = (DataSource)iC.lookup("java:env/jdbc/mySQL");
             java.sql.Connection connection = dataSource.getConnection();
             PreparedStatement st = connection.prepareStatement("SELECT name FROM test WHERE id='123'");
             ResultSet resultSet = st.executeQuery();
             while (resultSet.next()){
                  name = resultSet.getString("name");
                  name = name.toString();
             connection.close();
             return name;
             } catch(Exception n){
                  e = "Exception";
                  return e;
This is the method i put in the beans to test out the database connection.
