Java：应用程序在连接GSM USB调制解调器时崩溃

Question

我正在开发一个名为FrontlineSMS的开源应用程序，它可以与GSM调制解调器连接以发送和接收SMS。通过他们的网站可用的Windows安装程序工作正常。由于我想修改它，我得到了源代码并构建了jar并尝试启动它。当我插入GSM调制解调器并启动应用程序时，它有时会检测到GSM设备，我甚至可以发送和接收SMS。要不然 1）我收到以下错误 -

有谁知道是什么原因造成的？

Answer 1

EXCEPTION_ACCESS_VIOLATION（0xc0000005）表示在Windows中拒绝访问，通常是因为您没有权限/权限来执行您正在尝试执行的操作。

您构建的jar可能需要签名才能访问驱动程序。这告诉Java运行时，它的OK键进入系统驱动程序，文件系统等

这里有一个教程：http://java.sun.com/docs/books/tutorial/deployment/jar/signing.html

Answer 2

我们不得不看到代码，不只是在termios.c错误。最有可能的是，从Java调用的本地库存在错误。当您尝试访问已释放的内存中的变量时，通常会发生访问冲突错误。

Answer 3

我得到了和你一样的问题，我的解决方案很简单，我使用的是USB串行电缆，电缆很糟糕，我用一个不同的驱动器更换了更好的电缆，问题解决。该RxTxCom司机有问题，从“端口”越来越UART，这就是为什么崩溃，这里下面的解决方案发现了一些别的地方：

---

那行号。 SetupComm失败。

termios.c（869）：

 if(!SetupComm(port->hComm, 2048, 1024)) 
    { 
      YACK(); <===== 869 
      return -1; 
    } 

SetupComm是一个非常古老的W32 API调用，所以有一些不寻常的 的端口。

YACK（）是一个帮助宏，它只是吐出呼叫失败的原因。 “Yack， yack，yack！” :)

我的猜测是，这不是一个真正的串口，而是一个试图 看起来像一个[很差]的驱动程序。一个'真正'的串行端口有一个UART，通常不需要额外的驱动即可识别。根据我所知道的，我们无法通过 改善该函数调用。你可以看看 是否有一个新的'串口'驱动程序，如果我说的话对你来说有意义 。

我可以建议的另一件事是，当你试图用rxtx找到它时，你不希望任何其他 软件使用该端口。

希望它能帮助你。
