彩信网关接口mm7api的详细说明和实例

/*
 * @(#)SampleMMSCreation.java	1.0
 *
 *
 * This sample was derived from the OriginatingApp.java file which came with the
 * Nokia MMS Java Library 1.1
 *
 * Instead of sending the MMS to an MMSC, however, this sample simply writes the
 * encoded MMS to a file.  That file can then be used, e.g. with various tools
 * that are provided by Nokia -- the EAIF emulator, the Series60 terminal emulator
 * that comes with the Series60 SDK for Symbian OS, the 7210 simulator, etc...
 *
 * The sample is made as simple as possible while still pointing out key points
 * which are *not* explained in the samples that accompany the library.
 * For instance, many of the headers that were set in the original sample were set
 * to default values.  Those have been left out here for simplification.
 *
 * Note - this sample was changed with only limited knowledge of Java.  Java experts
 * are welcome to give feedback, and non-Java-experts may take heart that if we can
 * do it, you can too!
 *
 * Basic gist of this sample will be:
 * 1)Set headers
 * 2)Add various content parts
 * 3)Encode the message
 * 4)Write the encoded message to a file
 *
