File not found

I often get an error java.io.FileNotFoundException: /misc/res2/resin-2.0.5/doc/jsp/dc_menu.jsp.(Too many files open )
What is the reason for this error?

The most basic thing which its telling you :

A file is not found, either a file that you are using
or the dc_menu.jsp

Hope that helps . . .

Is it possible that you opened several files and never closed them?

After something like:   PrintWriter pw = new PrintWriter( ... what ever ... );
                                          .... writing ... writing ....
you must do:                       pw.close();

The same goes for reading.

;JOOP!

The follwoing post says increasing the available memory fixes the problem:

I read the article ... I think that everybody forgets that the number of open files
is merely an Operating System limit. You can't go on forever and raise your VM to 2Gb.
I don't know what the per-process limit is on actual systems (I tend to use a few files),
but, for instance, on Windows2000 it's easy to hit the all-system-limit ("out of resources").

I pretty much agree with you but if that is so then why would increasing the available memory get rid of the error.
