Java FTP文件到大型机

我正在尝试将JCL txt文件FTP到大型机：

// Connect to the server
        ftp.connect(host);
        replyText = ftp.getReplyString();
        System.out.println(replyText);

        // Log into the server
        ftp.login(userId, password);
        replyText = ftp.getReplyString();
        System.out.println(replyText);


        // Tell the server to use the JES interface
        ftp.sendSiteCommand("FILETYPE=JES");
        replyText = ftp.getReplyString();
        System.out.println(replyText);

        //read JCL file in input stream
        FileInputStream fileStream = new FileInputStream(file);

        String originalFileName = "ca7jcl.txt";

        ftp.setFileType(FTP.ASCII_FILE_TYPE);

        //store the JCL file
        ftp.storeFile(host, fileStream);
        replyText = ftp.getReplyString();
        System.out.println(replyText);

但是得到250，这是众所周知的未知

如何解决此问题？

我假设您希望在FTP'ed时运行JCL文本文件

封闭

try{}

和

catch{}

块（如果未完成）

以下是代码（这对我很有用）：

让我们知道这是否有帮助。：）

你能展示一下你得到的全部成果吗？好奇地想知道你是否希望它能有所帮助。看起来大型机正在反弹，可能是访问问题或打字错误。它工作正常@BillWoodger您遇到了什么错误？

// FTPClient ftp = new FTPClient(); Assumed in your code
//Connect to the server 
try
{
    ftp.connect(host);
    replyText = ftp.getReplyString();
    System.out.println(replyText);
} catch (Exception  e)  { e.printStackTrace () ; }

try

// Tell the server to use the JES interface
try

    ftp.site ("filetype=jes") ; 
    String replyText = ftp.getReplyString() ; 
    System.out.println (replyText) ;

//Submit the job from the text file.Use \\ to avoid using escape notation 
try

    String path = "" //Store your file's absolute path here 
    FileInputStream fileStream = new FileInputStream(path);

    ftp.storeFile(host, fileStream);
