Answer 1

时不时找不到数据源呀，看提示是unknown source

Answer 2

public static MM sendMessage(Send send) {

MM rsRes = null;
try {
SubmitReq req = new SubmitReq();

// 设置消息属性
req.setTransactionID(send.getTransactionID());

req.setVASPID(send.getSPID());
req.setVASID(send.getServiceID());
                                  try {
 System.out.println(req.getSender(+"ggggggggg");
 rsRes=（MM ）mm7Sender.send(req);
                 // System.out.println(rsRes+"fffffffffffffffff");
/*if (rsRes instanceof SubmitRes) {
SubmitRes submitRes = (SubmitRes)rsRes;
System.out.println("成功发送消息：submitRes.transactionID="
+ submitRes.getTransactionID()); } else {
System.out.println("不正确消息！rsRes.statuscode="
+ rsRes.getStatusCode() + ";rsRes.statusText="
+ rsRes.getStatusText());
}
} catch (Exception ex) {
System.out.println("发送失败，返回信息为：" + ex.getMessage());
}}} catch (Exception e) {
System.out.println("send mms error in MMSSend:" + e.getMessage());
}
当走到 rsRes=（MM ）mm7Sender.send(req);
时报上面的错误
并且那个send使直接调用包中的，
请问怎么解决啊，
