如何在Eclipse上运行Java Card Connected Edition Web示例

Question

我从Oracle官网下载Java Card Connected Edition 3.0.2并安装。在JCDK中有一些web示例。在文档中写:

所有示例必须在NetBeans IDE中运行。他们无法逃避这个开发工具包版本中的命令行。

Samples与NetBeans IDE正确工作。我可以导入它们并在Java Card Platform上运行。

但是我想在Eclipse IDE上使用这个示例。在Eclipse中作为Java Card SDK路径，我显示了Java Card Connected的主路径。然后创建新设备并尝试启动它[例如CardHolderApp]。但是Eclipse给出:

ApduTool thread exited
User input thread exited
APDU|ApduTool [v3.0.2]

APDU|Opening connection to localhost on port 9025.
APDU|Connected.
APDU|java.net.ConnectException: Connection refused: connect
ApduTool process finished with code: 1

. log文件:

是否可以在Eclipse IDE中运行Java Card Connected Web项目?

更新:

设备启动成功。但是项目没有部署。它在每次使用String时给出"不支持的String类型常量"。代码示例:

public void doGet(HttpServletRequest request, HttpServletResponse response) throws IOException, ServletException {
    response.setContentType("text/html"); // unsupported String type constant
    PrintWriter out = response.getWriter();
    RequestDispatcher dispatcher = null;
    dispatcher = request.getRequestDispatcher("/WEB-INF/header.i");//unsupported String type constant
    response.sendRedirect(response.encodeRedirectURL("http://www.sun.com"));//unsupported String type constant
    dispatcher.include(request, response);
    dispatcher.include(request, response);
}

经典版不支持字符串。但它必须在Connected Edition上运行

忘记中间所有复杂的软件。查看错误消息，看起来端口9025在本地主机上未打开或不可用:

APDU|Opening connection to localhost on port 9025.
APDU|Connected.
APDU|java.net.ConnectException: Connection refused: connect
ApduTool process finished with code: 1

文本[java.net.ConnectException: Connection refused: connect]，每次我看到"Connection refused"，这意味着java试图在端口上创建一个套接字(在这种情况下为9025)，并且由于阻塞(如防火墙)或不可用(其他东西正在使用端口9025)而无法获得端口号。

在windows或*nix上，您通常可以使用netstat命令查看正在使用的端口。
