Does etdFTPJ-PRO 7.6.0 support system parameters, specifically to set MaxQueuedReadRequests

Question

Hello,

We are getting this error on certain files

and saw in one reply to call setMaxQueuedReadRequests(1) prior to connection.

First question is what this actually accomplishes and secondly was wondering if it's also possible to set it through JVM System Properties with -D

which would make it much easier to configure things for compiled code instead of having

to add it in Java and re-compile

Thanks!

The server doesn't appear to support queued requests (which is a speed optimization), so you may need to call setMaxQueuedReadRequests(1). There's no way to set it through system properties, unfortunately.

Thanks for the quick answer! Appreciate it.

Does this look ok to you?

SSHFTPClient ftp = new SSHFTPClient();
ftp.setMaxQueuedReadRequests(1);

Thanks!

Yes, that's how to do it - prior to connecting.
