    Nokia MMS Java Library and Audio

    Hello there!
    I'm trying to send an encoded Multimedia Message to the EAIF Emulator. The message consists of a SMIL file with text, an image(jpg or gif) and an audio file (wav). As audio files are not supported by the Java Library, I added the new content type audio/x-wav. Everything works fine, the emulator shows a green light. But this is only a solution to satisfy the emulator. Audio is not on the list of the WAP Forum (where is the content type amr?), so the Java Library adds 0 and throws no exception.
    How can I encode and send a message with audio content?

    I hope somebody helps a poor student.
    Thanks in advance,

    I don't exactly understand the question. It seems that Pascal has already managed to both encode and send a message with audio content.

    But if you mean how are content-types such as audio/wav binary encoded into well-known bytes, then the answer is that they're not. Instead of a well-known byte, you simply see the bytes representing "audio/wav", null-terminated.

    As far as i know the content types wich not are in the WAP forum is encoded as plain text, so it should not matter.

    in order to send a mms with audio, you have only to set the right content type in the MMContent object. Here is an example:

    MMContent part3=new MMContent();
    byte [] buf3 = me.readFile(path+"000.amr"
    part3.setType("audio/amr" //content type for amr
    mm.addContent(part3); //mm is a MMMessage object

    In this way you can send all types of content that you want.

    In the Java MMS Library there are only some constants regarding the content-types. But anyway you don't need to use the defined constant (i.e IMMConstants.CT_IMAGE_JPEG, IMMConstants.CT_IMAGE_GIF, ecc.)
