Newbie Servlet getParameter() Problem!

Question

Hi there i'm trying to upload a file to a tomcat webserver. I'm using the import com.oreilly.servlet.MultipartRequest and that seems to work fine.
My problem is that i need to specify the directory to store the file by getting the users name.
i'm trying to use request.getParameter(user) but this doesn't seem to work. if i get the parameter using the MultipartRequest that works but the problem is that o need to know the user name before i create the MultipartRequest. Heres a copy of my code. if anyone could help i'd REALLY appriciate it!!!
import com.oreilly.servlet.MultipartRequest;
import javax.servlet.*;
import javax.servlet.http.*;
import java.util.*;
import java.io.*;
public class fileupload extends HttpServlet
     public void doPost(HttpServletRequest request,HttpServletResponse response)
                   throws ServletException,IOException
          response.setContentType("text/html");
          PrintWriter out = response.getWriter();
          try
               String uname      = request.getParameter("user");
               String pass      = request.getParameter("password");
               MultipartRequest multi = new MultipartRequest(request, "C:\\tomcat\\webapps\\301\\galleries\\"+uname,10*1024*1024);
                     database db = new database();
               db.setConnection(); 
               if(db.login(uname,pass))
                    File uploadedFile = multi.getFile("file");
                    InputStream bis = new BufferedInputStream(new FileInputStream(uploadedFile));
                    bis.close();
response.sendRedirect("http://localhost:8080/301/unpack_gallery.jsp?file="+uploadedFile.getName());
          catch(IOException ioe)
               System.out.println(ioe);
} Many Thanks Tom

I'm not familiar with the MultipartRequest package but it seems that you cannot go
easily with that. I think you have few options:
1) use the MultipartRequest package and provide a temporary filename in constructor.
Then get the user name and copy the file from the temporary directory to a appropriate
place with a appropriate name (including the username).
2) Or use jakarta commons file upload package which does the job for your.
Take a look at http://jakarta.apache.org/commons/fileupload/
