I am trying to use a PeopleCode app engine to delete files from a remote server. GetAttachment would work except that I want to loop through a the whole directory on the server and match files like march.csv.

Also, I am needing to do this by date range. *.csv between date 1 and date 2.

Get attachment seems to require that you know the file name and individually delete the files. So pattern pattern matching will not work.

I can get the list and check dates using java objects:

Local JavaObject &joFile = CreateJavaObject("java.io.File", SFO_DEL_FTP_AET.FTPDIRECTORY); Local JavaObject &joFileList; Local JavaObject &reflectArray = GetJavaClass("java.lang.reflect.Array"); Local JavaObject &dttm_format = CreateJavaObject("java.text.SimpleDateFormat", "yyyy-MM-dd");

but I can only use that with local servers.

Is there a way to actually connect to the server, then use the java objects?

Thanks, JPS

You could use Apache Commons NET library for this. One of the packages is intended for FTP/FTPS access.

FTPClient ftpClient = new FTPClient();
ftpClient.connect(server, port);
ftpClient.login(user, pass);
 
FTPFile[] files = ftpClient.listFiles("/yourDir");     

Once you get the file list, you could retrieve the name from the FTPFile object.

In order to delete a file, you could use FTPClient's deleteFile method.

public boolean deleteFile(String pathname)

Deletes a file on the FTP server. Parameters: pathname - The pathname of the file to be deleted. Returns: True if successfully completed, false if not.

 
for (FTPFile file : files) 
{
    String fileName = file.getName();
    /*if (file.isDirectory()) 
       handle directory access*/
    
    //use getAttachment from the fileName
  
    //in order to delete a file, call FTPClient's deleteFile Method  
    //ftpClient.deleteFile(filePath);
}

ftpClient.logout();
ftpClient.disconnect();

You can download the NET library here
