Some questions about "Sending email using java applet",thanks!!

[Zhao Wang]

Hello, everybody: I want to send email using Java applet (using Javamail
API) through Web (I installed J2SE-j2sdk1.4.1_02 and also jaf-1.0.2 and
javamail1.3.2), after I used signed applet, it ran perfectly by
appletviewer(I can received the email), but when running the applet through
the browser(IE6.0), the java consol shows 'java applet notinited'. And I
know the reason is due to .set sentence.

msg.setContent(message.getText(), "text/plain");
msg.setFrom(from);
msg.setRecipient(Message.RecipientType.TO, to);
msg.setSubject(subjectField.getText());


Can anybody tell me how to solve the problem? I was confused with this for
quite many days. I'd appriciate your help. Thank you.

The source code is followed:

import java.applet.*;
import java.awt.event.*;
import java.awt.*;
import java.util.*; import javax.mail.*; import javax.mail.internet.*;
import javax.activation.*;
