UnsupportedDataTypeException in "text/html"

Question

Hi,
I am facing the same problem. I want to send a mail in simple html format without any gif's and all. However I am getting this exception:
javax.activation.UnsupportedDataTypeException
at javax.activation.ObjectDataContentHandler.writeTo(DataHandler.java:
884)
at javax.activation.DataHandler.writeTo(DataHandler.java:313)
at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:980)

at javax.mail.Transport.send(Transport.java:73)
at Email.sendMail(Email.java, Compiled Code)
at MailTest.main(MailTest.java:76)
DEBUG SMTP SENT: quit
E-Mail not Sent!
javax.mail.MessagingException: Can't send command to SMTP host;
nested exception is:
java.net.SocketException: Descriptor not a socket: socket write error
at com.sun.mail.smtp.SMTPTransport.sendCommand(SMTPTransport.java:518)
at com.sun.mail.smtp.SMTPTransport.close(SMTPTransport.java:204)

at javax.mail.Transport.send(Transport.java:73)
at Email.sendMail(Email.java, Compiled Code)
at MailTest.main(MailTest.java:76)
The error is coming after this:
DEBUG SMTP SENT: rcpt to: <[email protected]>
DEBUG SMTP RCVD: 250 <[email protected]>: Recipient Ok
Verified Addresses
[email protected]
DEBUG SMTP SENT: data
DEBUG SMTP RCVD: 354 abc.com: Send data now. Terminate with "."
<<error comes here.....>>
As far as I know java activation framework does not support mime type like text/gif or text/jpg. Does it support text/html? Can I do this ->
message.setContent(htmlMess,"text/html");
Do I need to modify flavormap.properties file ?
How do I resolve this problem? Can you please help me?

You can find a SMTP Mailer Component that will easily send email messages, including attachments, at http://www.codecadet.com/components/ComponentDetail.aspx?ComponentID=ei47v8RePm0=.
