problem with exp utility when called remotely

I have problem with exp utility. I have export script which work fine when called on Oracle server computer. It's ok when we have application server on the same computer as database server. But sometimes we use another configuration. One computer as app server and another as db server.
The problem is on second configuration.
We have to make backup before one operation. We have to call exp from Java application. Locally it's ok but remotely we have to use exp user/pass_at_connection_string syntax. And that's the problem. Export fails.

Here is text from console:

My friend tested it on the same configuration on his system and realized the same fault. So the problem is probably on Oracle side. Have you seen this problem? Or even solved it? Is there any way to call exp from Java more effectively(script, method on server)? If so please tell me.

Thanks
