Problems with java app and remote dbase

I'm having trouble with my java app on the database side of things. It uses connec开发者_如何学CtorJ to communicate with a mysql dbase and works perfectly fine locally. When communicating with a remote dbase, it performs dismally. It's takes ages to start and windows that are supposed to open to display dbase data just say 'Exception in thread "AWT-EventQueue-0" java.util.NoSuchElementException' and prints a stack showing problems in places that work perfectly fine locally. On top of that, features like search and uploads(based on xml-rpc) do not work at all but are fine locally. Am I missing something big? Please help me out.

Have you investigated very carefully that you are not accidentially ignoring an error result or exception?

In other words, the code has told you something is wrong, but you keep continuing and you get lots of errors afterwards?
