Question

Hello guys, I'm having problems to use chmod with an outbound adapter, how can this be solved?

I gave a look around the code class FileTransferringMessageHandler, seems to be hardcoded

my dsl

  return flow -> flow
            .handle(Ftp.outboundGateway(FTPServers.PC_LOCAL.getFactory(), AbstractRemoteFileOutboundGateway.Command.MGET, "payload")
                .fileExistsMode(FileExistsMode.REPLACE)
                .filterFunction(ftpFile -> ftpFile.getName().contains("SCN") || ftpFile.getName().contains("REP") || ftpFile.getName().contains("EL"))
                .localDirectory(new File("/localTmp")))
            .log(Message::getPayload)
            .transform(GenericMessage.class, GenericMessage::getPayload)
            .split()
            .handle(Ftp.outboundAdapter(FTPServers.PC_LOCAL.getFactory(), FileExistsMode.IGNORE)
                .useTemporaryFileName(false)
                .chmod(666)
                .fileNameExpression("headers['" + FileHeaders.REMOTE_FILE + "']")
                .remoteDirectory("/dati/recpv"), e -> e.advice(afterFlow()));
    }

The FTP protocol does not support changing the file permissions, only SFTP.

The method is overridden in the SFTP message handler.

@Override
public boolean isChmodCapable() {
	return true;
}

Hello,
I'm using FTP protocol, I'm pretty sure that you can chmod using FTP (at least, as far as I know, you can do it with Filezilla), I tried too with ftp command line client on ubuntu and seems to be possible, I think it should be an enhancement?

[garyrussell]

I should have googled it when I implemented it for SFTP; there is no direct support in the Apache FTPClient - but it appears it can be done with a site command:

So yes; we will add it; in the meantime you can use an FtpRemoteFileTempalte to use that command from the session callback.

Thank you!

Hi guys,
I didn't made it in time to test the library, there's a bug that should be solved for it to work properly.

on the FtpMessageHandlerSpec, the target is still a FileTransferringMessageHandler, you have to use the children class you created FtpMessageHandler so that it can see the override, on my end it isn't working because isChmodCapable still returns false.

[garyrussell]

Please open a new issue - that was a pre-existing bug - clearly it wouldn't work for SFTP either.

thank you, working on it!
