I'm a newbie to JSPs and am trying to write a feedback form that validates
some of the fields, but not others. The problem is the bean never seems to
update its fields. Can you please help?
// Feedback.java
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import javax.mail.*;
import javax.mail.internet.*;
public class Feedback {
private static final String host = "mySmtpHost"; //this is a
valid host
private static final String from = "[EMAIL PROTECTED]";
private static final String to = "[EMAIL PROTECTED]";
private static final String subject = "Website Feedback";
private String title;
private String firstName;
private String surname;
private String company;
private String address;
private String telephone;
private String fax;
private String email;
private String comments;
private String how;
public void setTitle(String s) {
title = s;
}
public String getTitle() {
return title;
}
public void setFirstName(String s) {
firstName= s;
}
public String getFirstName() {
return firstName;
}
public void setSurname(String s) {
surname = s;
}
public String getSurname() {
return surname;
}
public void setCompany(String s) {
company = s;
}
public String getCompany() {
return company;
}
public void setAddress(String s) {
address = s;
}
public String getAddress() {
return address;
}
public void setTelephone(String s) {
telephone = s;
}
public String getTelephone() {
return telephone;
}
public void setFax(String s) {
fax = s;
}
public String getFax() {
return fax;
}
public void setEmail(String s) {
email = s;
}
public String getEmail() {
return email;
}
public void setComments(String s) {
comments = s;
}
public String getComments() {
return comments;
}
public void setHow(String s) {
how = s;
}
public String getHow() {
return how;
}
public void sendMessage()
throws Exception {
//Get system properties
Properties props = System.getProperties();
//Setup mail server
props.put("mail.smtp.host", host);
//Build up message body
String body = "This message has been automatically generated
- do not reply to this address.\n\n";
body = body + "From: " + title + ". " + firstName + " " +
surname + "\n";
body = body + "Company: " + company + "\n";
body = body + "Address: " + address + "\n";
body = body + "Telephone: " + telephone + "\n";
body = body + "Fax: " + fax + "\n";
body = body + "Email: " + email + "\n";
body = body + "Comments: " + comments + "\n";
body = body + "How: " + how + "\n";
//Get session
Session session = Session.getInstance(props,null);
//Define message
MimeMessage message = new MimeMessage(session);
message.setFrom(new InternetAddress(from));
message.addRecipient(Message.RecipientType.TO, new
InternetAddress(to));
message.setSubject(subject);
message.setText(body);
//Send message
Transport.send(message);
}
