How to manage the PDF file

Question

Dear all,
I have one question about Servlet. I have been using the Sun Java Application Server 8.0.
0) Obtains the inputs (name, birthday) from the user
1) Creates a PDF file, in which the inputs obtained are to be written
2) Stores the PDF file in the external hard disk drive
3) Only permits the same user to review the file
My question is how to let the permitted user to view the file.
a) Creates an HTML file with an appropriate Content-Type value
b) Exports the PDF file to the HTML file
If you are familiar with this problem, could you please help me to solve it?
Thank you very much in advance.
Yours faithfully,
