java - Spnego Keytab测试给出了Java安全异常

我无法运行以下程序：

import java.net.URL;

import net.sourceforge.spnego.SpnegoHttpURLConnection;

public class HelloKeytab {

    public static void main(final String[] args) throws Exception {
        System.setProperty("java.security.krb5.conf", "krb5.conf");
        System.setProperty("sun.security.krb5.debug", "true");
        System.setProperty("java.security.auth.login.config", "login.conf");

        SpnegoHttpURLConnection spnego = null;

        try {
            spnego = new SpnegoHttpURLConnection("spnego-client");
            spnego.connect(new URL("http://as1.test.local/hello_spnego.jsp"));

            System.out.println("HTTP Status Code: "
                    + spnego.getResponseCode());

            System.out.println("HTTP Status Message: "
                    + spnego.getResponseMessage());

        } finally {
            if (null != spnego) {
                spnego.disconnect();
            }
        }
    }
}

我安装了JDK7，并将JAVA_HOME环境变量设置为管理员。
我在Windows XP计算机上以常规域用户的身份进行编译和运行。

我将spnego-r7.jar与HelloKeytab.java放在同一目录中，并使用以下命令进行编译：

javac -cp .;spnego-r7.jar HelloKeytab.java

成功创建了类。

当我运行程序时：

java -cp .;spengo-r7.jar HelloKeytab

我收到以下错误：

spnego-r7.jar可以在这里找到：http://sourceforge.net/projects/spnego/files/

我收到此错误有什么问题？

最佳答案

我在login.conf中出错。

spnego-client {
    com.sun.security.auth.module.Krb5LoginModule required;
    storeKey=true
    useKeyTab=true
    keyTab="file:///C:/sys-spn.keytab"
    principal=sys-spn;
};

所需的分号不应该在那里！
