javamail的中文问题

sheek 2002-09-25 12:15:21

为什么在javamail里用普通的中文转换行不通呢？
为什么还是有那么多乱码？
请高手帮忙？
提醒一下小弟应该怎么解决？
谢谢！

中文转换怎么普通法？？你是怎么样转换的？

try{
String temp_p = str;
byte[] temp_t = temp_p.getBytes("ISO8859-1");
String temp = new String(temp_t,"GBK");
return temp;
}catch(Exception e){}

this is main.html:

<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>

this is sendmail.jsp:

<%@ page contentType="text/html;charset=gb2312" 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.setSubject(new String(request.getParameter("subject").getBytes("ISO-8859-1")));
newMessage.setSentDate(new Date());
newMessage.setText(new String(request.getParameter("text").getBytes("ISO-8859-1")));
transport = sendMailSession.getTransport("smtp");
transport.send(newMessage);
%>
<P>Your mail has been sent.</P>
<%
}
catch(MessagingException m)
{
out.println(m.toString());
}
%>
</BODY>
</HTML>
