Ftplet file upload

[Brooks Lyrette-2]

Hey Guys,

I'm looking at using a Ftplet to intercept file uploads and write them  
to another location. I have tried overriding public FtpletEnum  
onUploadStart(FtpSession ftpSession, FtpRequest ftpRequest) throws  
FtpException, IOException with:

public FtpletEnum onUploadStart(FtpSession ftpSession, FtpRequest  
ftpRequest) throws FtpException, IOException {
           File temp = File.createTempFile("upload", "ftp");
           OutputStream stream = new  
FileOutputStream(File.createTempFile("upload", "ftp"));
         try {
             //tell the client 150 so he sends the file
             DataConnection dataConnection =  
ftpSession.getDataConnection().openConnection();
             dataConnection.transferFromClient(stream);
             stream.flush();
             stream.close();
             ftpSession.getDataConnection().closeDataConnection();
         }
         catch(Exception e) {
             logger.error("Could not upload file", e);
         }
         return FtpletEnum.RET_SKIP;
     }

The file does not transfer. This is probably because I never sent a  
"150: File status okay; about to open data connection." To the client.  
I can not seem to figure out how to send that. The FAQ on the site  
explains how to send files from the database but the signature of the  
interface differs from what I see in SVN.

Any thoughts/Comments on how I can do this would be appreciated!

Thanks,

Brooks Lyrette

We should really do an example of this on the web site...

Besides that, and without Eclipse available at the moment to test this
code, you should be able to do:
session.write(new DefaultFtpReply(150, "File status okay; about to
open data connection."));

Thanks Niklas,

I somehow had overlooked using session.write(). I have it working and  
and here is the example for the site (Using todays M3 release):

public FtpletResult onUploadStart(FtpSession ftpSession, FtpRequest  
ftpRequest) throws FtpException, IOException {
         File temp = File.createTempFile("upload", "ftp");
         OutputStream stream = new FileOutputStream(temp);
         try {
             ftpSession.write(new DefaultFtpReply(150, "File status  
okay; about to open data connection."));
             DataConnection dataConnection =  
ftpSession.getDataConnection().openConnection();
             dataConnection.transferFromClient(stream);
             stream.flush();
             stream.close();
             ftpSession.getDataConnection().closeDataConnection();
             ftpSession.write(new DefaultFtpReply(226, "Closing data  
connection. Requested file action successful"));
         }
         catch(Exception e) {
             logger.error("Could not upload file", e);
         }
         return FtpletResult.SKIP;
     }

Cheers,

Brooks

Thanks,I'll add that as an example on the site.
