如何在Eclipse上运行Java Card Connected Edition Web示例？

Question

我从Oracle官方网站下载了Java Card Connected Edition 3.0.2并进行了安装.JCDK中有一些网络样本.在编写的文档中:

必须在NetBeans IDE中运行所有示例.它们无法在此版本的开发工具包中从命令行运行.

示例正确地与NetBeans IDE一起使用.我可以导入它们并在Java Card Platform上运行.

但我想在Eclipse IDE上使用这些示例.在Eclipse中作为Java Card SDK路径,我展示了Java Card Connected主路径.然后创建了新设备并尝试启动它[ 例如CardHolderApp ].但是Eclipse给出了:

ApduTool thread exited
User input thread exited
APDU|ApduTool [v3.0.2]
APDU|    Copyright (c) 2009 Sun Microsystems, Inc.

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:

设备已成功启动.但项目未部署.它在每个String使用时给出"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Strings.但它必须适用于Connected Edition.

忘记中间所有复杂的软件。只需查看错误消息，您的本地主机上的端口 9025 似乎未打开或不可用：

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: 连接被拒绝: 连接]，每次我看到“连接被拒绝”时，这意味着 java 尝试在端口（本例中为 9025）上创建套接字，并且由于以下原因无法获取端口号阻塞（如防火墙）或不可用（其他东西正在使用端口 9025）。

在 Windows 或 *nix 上，您通常可以使用 netstat 命令来查看正在使用哪些端口。
