Start with the obvious, since you are managing files on the file system make sure that the file permisions and file paths are correct and the servlet can access the files.

I had some problems so I'll get logs only now...

### I'm connecting to the remote computer with tomcat and my webapp with Firefox 1.0.7 - the webapp seems to work.. but I get that error when the app tries to load a db present (the app uses normal XML files as db)

ah... I've just installed tomcat on my new pc and it gives the same error... so now I can't run it on WIndows :-/

note: the web app works.. it fails when i use recMan class (through recManServ called by my index.jsp)... so I can't load forms with a database with 1 or more elements... but some of them loads... but they didn't show any element at all (only the total records number)...
