put() hangs

Question

I am using the following code:

if( ! asciiType ) 
            m_client.setType( FTPTransferType.BINARY );
        else
            m_client.setType( FTPTransferType.ASCII );
        
        
        if(usePassive)
            m_client.setConnectMode( FTPConnectMode.PASV );
        else
            m_client.setConnectMode( FTPConnectMode.ACTIVE);
        
        m_client.put( file.getCanonicalPath(), remoteName );

Everything seems to work fine until I tried connecting to an FTP server over the internet. I can retrieve and put files on the server for a while, then suddenly it just hangs. It is not the local file as it happens on different files. I cannot seem to find any consistancy.

The server throws a 553 data transfer failed error, yet the client still sits there.

I have a timeout of 15000 on the socket, and it doesnt timeout either. I left it running for 5 minutes without a timeout exception.

This is happening on Windows XP running JDK 1.4.2-b28, edtftpj-1.4.5.

Thanks!

sorry for the delayed reply, we've been busy.

unfortunately the timeout value is for reading data from the socket (i.e. downloads), not writing to the socket (uploads). This is a function of the Java API, not our implementation - see setSoTimeout.

at some point we'll look at moving to the async socket API, which is a bit more flexible in this area.
