Java 通过zehon.jar连接到SFTP

我正在尝试连接到本地主机上的SFTP服务器。我在zehon网站上做了一个例子，但我有一些错误。我使用freeshd作为我的SFTP服务器，它在fileZilla中工作良好

sftptest.java

import java.io.BufferedInputStream;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;

import com.zehon.exception.FileTransferException;
import com.zehon.sftp.SFTP;



public class sftptest {

    public static void main(String[] args) throws FileNotFoundException {
        // TODO Auto-generated method stub

        InputStream is = null;
        String filePath = "C:/DATA/echo.txt";
        File localFile = new File(filePath);        
        is = new BufferedInputStream(new FileInputStream(localFile));
        String destFolder = "/";
        String nameOfFile = "echo.txt";
        int status = -1;
        try {

            status = SFTP.sendFile(is, nameOfFile, destFolder,"127.0.0.1", "test", "test" );
        } catch (FileTransferException e) {
            e.printStackTrace();
            //or
            //ex.getCause().printStackTrace();  (
            //Depending on what version of JDK you use)         
        }finally{
            if(is != null){try {is.close();} catch (IOException e) {}}
        }
    }

}

以及启动应用程序时的错误：

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/commons/vfs/FileSystemException
    at com.zehon.sftp.SFTP.getSFTPClient(SFTP.java:20)
    at com.zehon.sftp.SFTP.sendFile(SFTP.java:110)

确保在类路径中。

确定。谢谢，这还不行，因为这是问题之一，现在我需要另一个库。
