How to add mailcap file to service assembly (UnsupportedDataTypeException)

[sorin7486]

Hello,

        I am trying to send a signed MimeBodyPart  via HTTP and I got stuck when trying to convert it: when I try to do writeTo I get the folowing error:

javax.activation.UnsupportedDataTypeException: application/pkcs7-mime; name=smime.p7m; smime-type=signed-data

     at javax.activation.DataHandler.writeTo(DataHandler.java:75)

     at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:1383)

     at javax.mail.internet.MimeBodyPart.writeTo(MimeBodyPart.java:852)

I tried to add that data type to the MailcapCommandMap but it didn't help. I also tried to add a mailcap file but nothing changed. Any ideas?

Thank you,

                  Sorin.
