Send Japanese Characters In Java Mail

[Nitin Sinha]

I have been using the following code in my program to send mail in English -

    
            System.out.println("Sending mail...");
            Properties props = new Properties();
            props.setProperty("mail.transport.protocol", "smtp");
            props.setProperty("mail.host", "smtp.myhost.com");
            
            Session mailSession = Session.getDefaultInstance(props, null);
            mailSession.setDebug(true);
            Transport transport = mailSession.getTransport();
        
            MimeMessage message = new MimeMessage(mailSession);
            message.setSubject("THIS IS MY SUBJECT LINE");
            message.setFrom(new InternetAddress("[e-mail]"));
            message.setContent("HELLO HOW ARE YOU DOING TODAY", "text/html");
            
            message.addRecipient(Message.RecipientType.TO, new InternetAddress(to));
            
            transport.connect();

            transport.sendMessage(message, message.getRecipients(Message.RecipientType.TO));
            
            transport.close();

But, now I have a requirement to send Japanese characters in mail.
I tried to google alot but couldn't find a viable solution.
Can anyone assist me with the code (if possible)

When I try to harcode Japanese Characters ino Subject & Content Line, the mails outputs ??? in place of all the Japanese chractersets. Like this -

message.setSubject("全て半角英数字で");
message.setContent("定されていないシステム", "text/html");

I also tried using the code given at : http://www.example-code.com/java/java-japanese-email.asp

But this code throws me an exception stating :

java.lang.UnsatisfiedLinkError: new_CkMailMan
at com.chilkatsoft.chilkatJNI.new_CkMailMan(Native Method)

How are you verifying this? Using the console? Because then maybe it's a console problem, not a JavaMail problem.

I have this Java Mail embedded in a servlet which is called upon submission of a JSP form which consolidates all the inputs from the user in a mail and mails them to me. Now, I want to allow user to enter Japanese characters in the inut boxes So those Japanese characters should get mailed to me too.

But this is other part of the story. Even if i try to hardcode anything in the mailer Body content, it returns a mail to me which has all ??? wherever I hardcode Japanese characters

Ok, so it shows up wrongly in a mail client that usually can handle Japanese characters.

Can you set the charset in the emails? I found a website that used the following code:

msg.setContent(Content, "text/html; charset=ISO8859_1");

Surely you could try something similar?
