Where in server is file stored?

Question

When I upload a file using <input type="file"> in a HTML form and I give the action as <form action=auth> where 'auth' ia a servlet. Now I want to know that When user press Submit button where does the file reside? If in Servlet I want to retrieve the file, What should I do?
Edit
Now I read this file(pdf) using java libraries like

 public void doGet(HttpServletRequest req, HttpServletResponse resp) 
 {
try {
      String INPUTFILE=req.getParameter("filename");
      System.out.println(INPUTFILE);
      PdfReader reader = new PdfReader(INPUTFILE);
      int n = reader.getNumberOfPages();
      System.out.println(n);

      String str=PdfTextExtractor.getTextFromPage(reader, 2); //Extracting the content from a particular page.
      System.out.println(str);


} <br>

But it shows the following error java.io.IOException: java_learn.PDF not found as file or resource

The web server is getting a `POST` HTTP request. It can do whatever it wants with the data. — Basile Starynkevitch, Apr 25 '12 at 08:28
@Basile I want to retrieve that file using servlet? How should i do that? — suraj, Apr 25 '12 at 08:34
I don't know what you call a servlet! Perhaps it is a framework offering you some way of handling the data in the HTTP request? — Basile Starynkevitch, Apr 25 '12 at 08:38
public void doGet(HttpServletRequest req, HttpServletResponse resp) { String INPUTFILE=req.getParameter("filename"); System.out.println(INPUTFILE); PdfReader reader = new PdfReader(INPUTFILE);} Now it is not retrieving the pdf file — suraj, Apr 25 '12 at 08:44
@PrakashK It gives error at this line PdfReader reader = new PdfReader(INPUTFILE); as INPUTFILE just gives the name of file and not the complete path — suraj, Apr 25 '12 at 09:19

As stated in the HTML specification you have to use the POST method and the enctype attribute of the form has to be set to "multipart/form-data".
