利用一下代码可以在JSP页面中发信
<HTML>
<BODY>
<FORM action="sendmail.jsp" method="post">
<TABLE align="center">
<TR>
<TD width="50%">
To:<BR><INPUT name="to" size="25">
</TD>
<TD width="50%">
From:<BR><INPUT name="from" size="25">
</TD>
</TR>
<TR>
<TD colspan="2">
Subject:<BR><INPUT name="subject" size="50">
</TD>
</TR>
<TR>
<TD colspan="2">
<P>Message:<BR><TEXTAREA name="text" rows=25 cols=85></TEXTAREA></P>
</TD>
</TR>
</TABLE>
<INPUT type="submit" name="cb_submit" value=" Send ">
<INPUT type="reset" name="cb_reset" value=" Clear ">
</FORM>
</BODY>
</HTML>
///sendmail.jsp/////
<%@ page
import=" javax.mail.*, javax.mail.internet.*, javax.activation.*,java.util.*"
%>
<html>
<head>
<TITLE>JSP meets JavaMail, what a sweet combo.</TITLE>
</HEAD>
<BODY>
<%
try{
Properties props = new Properties();
Session sendMailSession;
Store store;
Transport transport;
sendMailSession = Session.getInstance(props, null);
props.put("mail.smtp.host", "smtp.jspinsider.com");
Message newMessage = new MimeMessage(sendMailSession);
newMessage.setFrom(new InternetAddress(request.getParameter("from")));
newMessage.setRecipient(Message.RecipientType.TO, new InternetAddress(request.getParameter("to")));
newMessage.setSubject(request.getParameter("subject"));
newMessage.setSentDate(new Date());
newMessage.setText(request.getParameter("text"));
transport = sendMailSession.getTransport("smtp");
transport.send(newMessage);
%>
<P>Your mail has been sent.</P>
<%
}
catch(MessagingException m)
{
out.println(m.toString());
}
%>
</BODY>
</HTML>
但是我在WIN2000 SERVER+RESIN的环境下进行调试，出现以下错误：
500 Servlet Exception
/class/sendmail.jsp:11: Package javax.mail not found in import.
import javax.mail.*;
^
/class/sendmail.jsp:12: Package javax.mail.internet not found in import.
import javax.mail.internet.*;
^
/class/sendmail.jsp:13: Package javax.activation not found in import.
import javax.activation.*;
^
3 errors
不知为什么？而且我也下载了JAVAMAIL和JAF，放到了JDK的LIB中。
请高手们给与指教！！！！！
