File Lookup on File Server Using the FTP Credentials

There could be requirement when we have to do a file lookup on different server. My previous code will work when we have server mounted over our PI/PO system. From below code snippet you can do a lookup on any FTP server with the help of credentials.

Below is the code:

String host = "<hostname>";

int port = 21;

String username = "anonymous";

String password = "pwd123";

String str = "";

FTPClient ftpClient = new FTPClient();

try {

    ftpClient.connect(host, port);

    ftpClient.login(username, password);

    ftpClient.enterLocalPassiveMode();

 

    String remoteDirPath = "/sap/PO1/PO_Test/Training/Rahul/Input";

 

   FTPFile[] files = ftpClient.listFiles(remoteDirPath);

 if (files != null && files.length > 0) {

            for (FTPFile aFile : files) {

                str = aFile.getName();

result.addValue(str);

// str = str + currentFileName;

}

      }

result.addValue( "Connection Successful");

    ftpClient.logout();

    ftpClient.disconnect();

} catch (IOException ex) {

    System.err.println(ex);

}

This code can be used for anonymous login also. If you are doing anonymous login on FTP server then password string must be blank.
