Question

我正在尝试以下代码连接到SFTP服务器

    final String sftpURL = <<my hostname here>>;
    final String username = <<username here>>;
    final String password = <<password here>>;
    SshParameters params = new SshParameters(sftpURL,username,password);            
    Sftp ftp = new Sftp(params);

    // Connect, upload PNG images and release the connection.
    ftp.connect();        
    ftp.disconnect();

当尝试连接时，它抛出了以下错误:::

上面的代码几个月前才开始运作。但现在它抛出了错误。我也下载了最新版本的sinet-factory.jar。有人可以帮我解决这个问题吗？

Answer 1

问题是因为它需要在CLASSPATH中再添加一个jar bcprov-ext-jdk15on-148.jar 以及sinetfactory.jar 我补充说，问题解决了。

感谢。

使用sinet工厂连接到SFTP服务器
