我正在尝试使用MPI发送和接收字符串,但结果是无跳的.

发送功能:

MPI_Send(&result, result.size(), MPI_CHAR, 0, 0, MPI_COMM_WORLD);

和recv功能:

    MPI_Recv(&result,      /* message buffer */
        128,                 /* one data item */
        MPI_CHAR,        /* of type char real */
        MPI_ANY_SOURCE,    /* receive from any sender */
        MPI_ANY_TAG,       /* any type of message */
        MPI_COMM_WORLD,    /* default communicator */
        &status);          /* info about the received message */

结果是字符串.

我没有得到任何错误,但程序不想完成.

我正在尝试在 javaFX 中创建自定义光标。这是我的代码：

Image image = new Image("mycursor.png");

Pane pane= new Pane();
pane.setCursor(new ImageCursor(image,
                                image.getWidth() / 2,
                                image.getHeight() /2));

Windows 8.1 的光标创建不起作用吗？

我有编译jar的问题.当我做mvn包蚂蚁尝试运行它然后我得到错误无法找到或加载主类.
