From JSP, when you submit the form, then you need to call a Java class in which you write code for sending mail using JavaMail. You can find an example here http://code.geekinterview.com/java/send-email-using-gmail-mail-server.html:
在 JSP 中，当您提交表单时，您需要调用一个 Java 类，您可以在其中编写使用 JavaMail 发送邮件的代码。你可以在这里找到一个例子 http://code.geekinterview.com/java/send-email-using-gmail-mail-server.html：
//set CLASSPATH=%CLASSPATH%;activation.jar;mail.jar
import javax.mail.*;
import javax.mail.internet.*;
import java.util.*;
public class Mail
{
String d_email = "[email protected]",
d_password = "****",
d_host = "smtp.gmail.com",
d_port = "465",
m_to = "[email protected]",
m_subject = "Testing",
m_text = "Hey, this is the testing email using smtp.gmail.com.";
public static void main(String[] args)
{
String[] to={"[email protected]"};
String[] cc={"[email protected]"};
String[] bcc={"[email protected]"};
//This is for google
Mail.sendMail("[email protected]","password","smtp.gmail.com","465","true",
"true",true,"javax.net.ssl.SSLSocketFactory","false",to,cc,bcc,
"hi baba don't send virus mails..","This is my style...of reply..
If u send virus mails..");
}
public synchronized static boolean sendMail(String userName,String passWord,String host,String port,String starttls,String auth,boolean debug,String socketFactoryClass,String fallback,String[] to,String[] cc,String[] bcc,String subject,String text){
Properties props = new Properties();

try

session.setDebug(debug);
MimeMessage msg = new MimeMessage(session);
msg.setText(text);
msg.setSubject(subject);
msg.setFrom(new InternetAddress("[email protected]"));
for(int i=0;i<to.length;i++){
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(to[i]));

msg.saveChanges();
Transport transport = session.getTransport("smtp");
transport.connect(host, userName, passWord);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();
return true;

catch (Exception mex)
{
mex.printStackTrace();
return false;
}
