Are you printing out all your exceptions? If you are not, you are losing valuable debugging information. I would not expect a network operation to fail silently.
Are you using the same level of JVM on both machines? The same version of code? There can be serialization problems if you are not.

No one said why, but I can guess. On many Linux machines, the default setup will firewall out ports 1098 and 1099.

Too true. Only port open on my linux box is the port I mapped ssh onto. Had to change from default port too because some idiot keeps banging my ssh port trying to break in when I dont even allow password authentication...

Welcome to the club. The #1 attack for my systems seems to be DOS against FTP, but there's a dozen or so ports that get hammered all day long. Once long ago, I actually did have a server get pwned courtesy of an SSL breakin.

Downside of using nonstandard ports is that when I'm on the road, attempts to SSL in via an unusual port number a lot of public Internet service providers block me. Such is life.
 
I agree. Here's the link: http://aspose.com/file-tools
