In this example, we could have easily used HTML instead of this JSP page. We
opted to use a JSP to assist with handling prepopulation of the form with
input parameters. We were also able to dynamically create the text that showed
the board. However, we have no controller or command, because this JSP data
does not need any input from command beans.
The model for AddPost
The following classes will take the user's responses on the reply.jsp form and
add them to the database. If we're successful, instead of returning a new JSP
we'll return the user to the ShowBoardResults.jsp view via ShowBoardCon-
troller . Here is the AddPostCommand :
package bbs;
import java.sql.*;
import java.util.*;
public class AddPostCommand {
Here are the usual imports that we use in the rest of our commands:
private String author = null;
private String subject = null;
private String board = null;
private String parent = "0";
private String postText = null;
private ResultSet result;
private Connection connection = null;
private String query = null;
