      hi guys,
      i had question. i had a mail program in java with sending attachment.
      ok fine it's working good in tools like jdev,netbeans,ecliapse.

      but i want to run the same program in command prompt "D:\Oracle\Middleware\jdk160_24\bin"
      it's running. no error but no mail sending and no attachment sending.

      so my question is:? same program in jdev can able to send mail & with attachment.
      but in command prompt it doesnt work's so what would be a reason?

      anything special in jdev11.

              There's no error messages because you eat all exceptions and turn them into a return code, and you never print out the return code, so we have no idea what may have gone wrong.

                  When you Google for that exception "javax.activation.UnsupportedDataTypeException: no object DCH for MIME type multipart/mixed;" then all will become clear

                    john is perfect always :) as my colleague told.

                    this one helped me while googling against this exception
                    Re: javax.activation.UnsupportedDataTypeException:

                    i found out my first mistake.
                    i extracted jar. as this thread says i did it.

                    second thing. i caught noclassdef error. i understood classpath is not setuped correctly.
                    so i follow this

                    after putting this dot and semicolon my program i identied the class path.

                    now the problem solved. now i got a mail with attachment.

                    atlast i conclude that, extracting jar file and classpath missing is my real problem for sending mail with attachment.

                    great john hat's off brovao thousands of applause for guiding me in right way :)
