Question

我试图打开一个充满java .class文件的.exe文件..当我用鼠标点击打开它时它可以工作但是当我用我的Java应用程序打开它时我得到了一个JNI错误

该程序名为PokeMMO.exe 网站：PokeMMo

我试图获取输出流...这里是代码：

public static void main(String[] args) throws Exception {
    System.out.println("STARTING");
    System.out.println();

    Runtime rt = Runtime.getRuntime();
    String[] commands = {"C:\\Users\\{MY USER NAME}\\AppData\\Roaming\\PokeMMO\\PokeMMO.exe"};
    Process proc = rt.exec(commands);


    BufferedReader Input = new BufferedReader(new InputStreamReader(proc.getInputStream()));
    BufferedReader Error = new BufferedReader(new InputStreamReader(proc.getErrorStream()));



    System.out.println("OUTPUT:\n");
    String s = null;
    while ((s = Input.readLine()) != null) {
        System.out.println(s);
    }
    System.out.println("ERROR OUTPUT:\n");
    while ((s = Error.readLine()) != null) {
        System.out.println(s);
    }
}

我读到了一些关于在流程中添加libary路径的内容.. 知道如何修复它吗？

您的源代码对我来说很好。此处PokeMMO.exe缺少Java库。

请使用您已安装PATH的地方PokeMMO，即（C:\\Program Files或C:\\Program Files (x86)或C:等），而不是使用{{1} }：

“C：\ Users \ {MY USER NAME} \ AppData \ Roaming \ PokeMMO \ PokeMMO.exe”
