Let me give you a back ground of my webapp.
tomcat is under /root/apache* directory, I have given a link to actual
source files and uploaded files stored in the webapps directory of
apache.
The actual files are stored under another users home/projects
directory.
So when a web user uploads some files it is being stored at above
mentioned location and when I want to convert the files to pdf I'm am
not having write permissions to the files as the UID for these files
is 65534.
Now, please tell me what should I do so that whenever files are
uploaded they are stored with the user's name where all code and other
files are stored.

That depends in great measure on the deployment environment (Tomcat?
WebSphere?), but ultimately on what user ID the application runs under.
Presumably it's running as 'nobody', right?

This is actually a Linux question - check your HOW-TOs and the documentation
for your application server. I usually just run the startup script under the
desired user ID.

Another thing you can do is run a 'chmod' script that's setuid to root.
