+ *
+ * DataHandler dh = proxy.getData();
+ * StreamingDataHandler sdh = (StreamingDataHandler)dh;
+ * // readOnce() doesn't store attachment on the disk in some cases
+ * // for e.g when only one huge attachment after soap envelope part in MIME message
+ * InputStream in = sdh.readOnce();
+ * ...
+ * in.close();
+ * sdh.close();
