我正在尝试使用Jsch在Java中建立SSH连接.我的代码产生以下异常:

com.jcraft.jsch.JSchException: UnknownHostKey: mywebsite.com. 
RSA key fingerprint is 22:fb:ee:fe:18:cd:aa:9a:9c:78:89:9f:b4:78:75:b4

我找不到如何在Jsch文档中验证主机密钥.我在下面提供了我的代码.

import com.jcraft.jsch.JSch;
import com.jcraft.jsch.Session;

public class ssh {
    public static void main(String[] arg) {

        try {
            JSch jsch = new JSch();

            //create SSH connection
            String host = "mywebsite.com";
            String user = "username";
            String password = "123456";

            Session session = jsch.getSession(user, host, 22);
            session.setPassword(password);
            session.connect();

        } catch(Exception e) {
            System.out.println(e);
        } 
    }
}

我们公司最近从Windows XP升级到Windows 7企业版.JDK安装不再将user.home设置为用户目录的完整路径,而是将user.home设置为%userprofile%.这对Eclipse,Maven等应用程序造成了很多问题.我现在必须在JVM中为每个应用程序设置-Duser.home.还有其他人经历过这个吗？有没有解决这个问题？这与Windows 7企业版的安装有关吗？我试过1.5 JDK和1.6 JDK.

这是属性列表.注意user.home:

我完全失去了这个:System.getProperty("user.home")并System.getProperty("user.name")返回一个问号"？".

System-Specs:
Kubuntu 9.04
Gnome 2.2.61
Java 1.5.0_16

我的测试用例看起来像这样:

$ more Test.java
class Test { public static void main( String[] args ) { System.out.println( System.getProperties() ); } }

结果是(添加换行符以提高可读性,替换公司名称和自己的名称):
