    Send MMS, only works in debug mode


    i have a MIDlet that opens an mms port (like this
    ) and the same midlet, running on a different phone may eventually send an mms to another phone (running the very same MIDlet). The code to send the mms looks like this:

    String address = "mms://"+cellPhoneNumber+":54531";
    MessageConnection clientConnection = (MessageConnection)Connector.open(address);
    MultipartMessage multipartMessage = (MultipartMessage)clientConnection.newMessage(MessageConnection.MULTIPART_MESSAGE);
    MessagePart bandyMessage = new MessagePart(
                                                aByteArrayOfSize454[],            /* the actual message content */
                                                BANDY_MESSAGE_MIME, /* mime type */
                                                BANDY_MMS_PAYLOAD,  /* part name */
                                                null,               /* no file name */
                                                null);              /* no encoding */
    I have two instance of SUNs WTK (version 2.2) running this applet, one waiting for the other to send an mms. With the code above, this works fine, BUT only in debug mode (i.e. inside eclipse, running eclipseME with the wtk). If not running in debug mode, I always get an ioexception:

    java.io.IOException: Connection closed
    	at com.sun.midp.io.j2me.datagram.Protocol.ensureOpen(+16)
    	at com.sun.midp.io.j2me.datagram.Protocol.newDatagram(+4)
    	at com.sun.midp.io.j2me.mms.DatagramImpl.send(+354)
    	at com.sun.midp.io.j2me.mms.Protocol.send(+473)
    Which is hard to belief, as I just opened the connection (
    just a few lines above!?

    Does anyone know this problem?

    Cheers, Phibo

    PS The same happens when using the nokia emulator (Nokia Dev Suite for JME 3.0, running S60)

    Me again,

    on the phone I've been able to track it down to a ClassNotFoundError, namely for the com/../symbian/.../mms/Protocol class.
    Is it possible, that the Nokia 6680 does not support MMS sending as defined in JSR-120?!?

    Thanx for sharing your experience.

    Make always a practice to close all the streams and other connections inside the finally block so that you can make sure that the resources were released. Search the web or even this link can help you,
    Thanks with Regards,
