How to store data from database & display

Question

I am trying to connect to the database Northwind through sqlserver.
My code is as follows
public String data() {
        try {
            System.out.println("Control is in fieldlist.data::::::::");
          Context context = new InitialContext();
          Map sessionMap=FacesContext.getCurrentInstance().getExternalContext().getSessionMap();
          FieldList flist=(FieldList)sessionMap.get("fieldList");
          DataSource dataSource =
            (DataSource)context.lookup("java:comp/env/jdbc/Northwind");
            System.out.println("dataSource::::::::"+dataSource.toString());
          Connection connection = dataSource.getConnection();
          System.out.println("connection::::::::"+connection);
          Statement statement = connection.createStatement();
          String query = generateQuery1();
          System.out.println("In data ::query::::::::"+query);
/* Problem Starts here */
         ResultSet resultSet = statement.executeQuery(query);
Result result=ResultSupport.toResult(resultSet);
System.out.println("result::::::::::::"+result);        
          return "success1";
        } catch(Exception e)
            System.out.println("Connection error "+e);
            return(null);
  }So on calling the method data() the above code is getting executed.
Here I am also able to print the value of result which comes in hexadecimal format.
But I am not able to display the data when I run the application.
May I know what I am doing wrong here.

Answer 1

Thanks.
But I want to know what is the method to extract values from ResultSet
while(resultSet.next())
                  //what should be the method here.
          }
