Apache can not find file.

I am working on this JSP web page in netbeans which uses the Apache
distribution which comes with the ide. My problem is that whenever a
user uploads a file via my web site then goes to view it Apache can
not find the file and returned a 404 error. However it can find all
other files in that directory and after I restart Apache it can find
all files now. Why?

Could it maybe be because whenever Apache is first run it takes a
snapshot of the file system and so that any files created while Apache
is running will not be visible because they are not included in the
snap shot.

Here is the error message...

HTTP Status 404 - /MyNotes/NoteFiles/8chapter1.doc

type Status report

message /MyNotes/NoteFiles/8chapter1.doc

description The requested resource (/MyNotes/NoteFiles/8chapter1.doc)
is not available.
Apache Tomcat/6.0.16

"NoteFiles/8chapter1.doc" does exist an can be found once I restart
the server.
