我正在使用eclipse进行开发，并且我已将包包含在构建路径中，但我仍然收到此错误。

Apache Tomcat/6.0.30

这是我正在使用的代码，

private void putFile(File f){
        Connection Conn = null;
          try {


           Conn = new Connection("servername");
           ConnectionInfo info = Conn.connect();
           Conn.authenticateWithPassword("username" , "password");
           SCPClient SCP = new SCPClient(Conn);

           SCP.put(f.toString(), "foldername", "0755");
           Conn.close();
          } catch (Exception e) {
           try {
            Conn.close();
           } catch (Exception e1) {}
    }
    }

任何想法？

需要将相关的jar文件（包含无法找到的类的文件）放在webapp的WEB-INF/lib目录中。仅将其添加到构建路径是不够的。

使用ganymed-ssh2包的java scp文件
