/**
 * The intended purpose of this testcase is to test the MTOM functions in Axis2. 
 * It demostrate an alternative way of sending an attachment using DataHandler.
 * 
 * This testcase uses a JAXWS Dispatch invocation with JAXB generated request object
 * as parameter. The endpoint for these testcase is a JAXWS Source Provider.
 * 
 * These JAXB generated artifacts is based on jaxws\test-resources\xsd\samplemtom.xsd
 * schema.
 * 
 * Available Content types are:
 *       "image/gif"
 *       "image/jpeg"
 *       "text/plain"
 *       "multipart/*"
 *       "text/xml"
 *       "application/xml"
 * This initial testcase only covers the "multipart/*" and  "text/plain" mime types.
 * The ultimate goal is to provide testcases for the remaining mime types.
