i solve all the error already. But when i do the testing for my send mail application, the email cannot reach the recipient. here i post my code, if i code something wrong please tell me thank you.
Form Code:

<html>
 
<head>
 
<title>Send Mail Application</title>
<script type="text/javascript">
function checking(){
 
if (document.all.toadd.value==""){
alert("Please fill in the email address to send the message");return false;}

}
</script>
</head>
 
<body background="ricebk.jpg" bgcolor="#FFFFFF" text="#000000" link="#666633" vlink="#333366" alink="#990000">
 
<font face="Times New Roman, Times">
 
<p><font face="Amelia BT" size="5" color="#FF0000"><marquee>Send Mail Application.</marquee></font></p>
 
<form method="POST" action="send.jsp" onsubmit="checking()">
 
<br>SMTP Host:<input type="text" name="host" size="40"></br>
<br>To:     <input type="text" name="toadd" size="78"></br>
<br>BCC: <input type="text" name="bccadd" size="78"></br>
<br>CC:    <input type="text" name="ccadd" size="78"></br>

<p> </p>
<p>Content:</p>
 
  <p><textarea rows="7" name="content" cols="81"></textarea></p>
 
<p> </p>
<p>                                                                  
<input type="submit" value="Send" name="B1">   <input type="reset" value="Reset" name="B2"></p>
</form>
</font>
</body>
 
</html>

this is my form code. i need to go in to this page to do my key in address message body and so on and i using smtp.mail.yahoo.com as my host.

send.jsp:

the jsp will call the bean file to send out the message. in the jsp will pass in the relevent information to sending message.

BEAN CODE:

package common;
import java.util.*;
import java.io.*;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;
 
 
public class sendMail{
public void sending(String SMTPServer,

                            String CcRecipient,
                            String BccRecipient,
                            String Subject,
                            String Body,
                            String Attachments){

// Setup mail server
props.put("mail.smtp.host", SMTPServer);

// Define message

try

    message.setFrom(new InternetAddress(Sender));
{

message.addRecipients(Message.RecipientType.TO,TheAddresses);
}

              InternetAddress[] TheAddresses = InternetAddress.parse(CcRecipient);
 
              message.addRecipients(Message.RecipientType.CC,TheAddresses);
           }
if (null != BccRecipient) {
              InternetAddress[] TheAddresses = InternetAddress.parse(BccRecipient);
 
             message.addRecipients(Message.RecipientType.BCC,TheAddresses);
           }

message.setSubject(Subject);
 // Create the Multipart to be added the parts to
           Multipart mp = new MimeMultipart();
 
           // Create and fill the first message part
           {
              MimeBodyPart mbp = new MimeBodyPart();
              mbp.setText(Body);
 
              // Attach the part to the multipart;
              mp.addBodyPart(mbp);
           }
 
           // Attach the files to the message
           if (null != Attachments) {
              int StartIndex = 0, PosIndex = 0;
              while (-1 != (PosIndex = Attachments.indexOf("///",StartIndex))) {
                 // Create and fill other message parts;
                 MimeBodyPart mbp = new MimeBodyPart();
                 FileDataSource fds =
                 new FileDataSource(Attachments.substring(StartIndex,PosIndex));
                 mbp.setDataHandler(new DataHandler(fds));
                 mbp.setFileName(fds.getName());
                 mp.addBodyPart(mbp);
                 PosIndex += 3;
                 StartIndex = PosIndex;
              }
              // Last, or only, attachment file;
              if (StartIndex < Attachments.length()) {
                 MimeBodyPart mbp = new MimeBodyPart();
                 FileDataSource fds = new FileDataSource(Attachments.substring(StartIndex));
                 mbp.setDataHandler(new DataHandler(fds));
                 mbp.setFileName(fds.getName());
                 mp.addBodyPart(mbp);
              }
           }
 
           // Add the Multipart to the message
           message.setContent(mp);
 
           // Set the Date: header
           message.setSentDate(new Date());
 
           // Send the message;
           Transport.send(message);
}
 
catch (MessagingException e)
{
    System.err.println("Caught Exception: " 
                      + e.getMessage());
 
}
 
}
}

this is the bean file that use to send out the message to the recipient.

albert, please read this and in the future, use a more meaningful subject for your posts. "PleaseHELP Me !!!~~~" doesn't convey one iota of information about your problem.

I have adjusted the subject line of this topic to better suit the question.

You'd be best served to factor all that Java code out of your JSP and into a bean or servlet.

But in any case, the JavaMail API is best discussed in the Other Java APIs forum, so this topic has been moved there.

the email cannot reach the recipient.

What does this mean? Can you connect to the email server? Is the email sent? What do you see in the log files of the email server?

Stuff like this is hard to get right in a JSP; I'd advise to follow Bears suggestion of using a bean or a servlet. You could also use one of any number of SMTP classes that are available on the web, instead of writing your own.

And just to nitpick: the fact that no message arrives at your account does not mean that no message was sent. That's why it's helpful to use a mail server you control for testing purposes, so you can check the log files.

Yahoo doesn't do relaying. They don't want to have people using their accounts to send out spam.

You're testing an application? So when it goes live, will you be using some other server? If so, that will be a server where you can work with the administrator to make sure it will send out your e-mail messages, right? You should get together with that administrator sooner rather than later to learn the facts of life with respect to Internet e-mail.

Otherwise your project may be in trouble. Administrators of e-mail servers don't open their systems to everybody in the world. They need to know who you are, and they need to know that you won't be sending spam. Yahoo can't do that.
