What is the error in my code? It is not making a new file which contains the string values coming from a HTML page. Any help appreciated.

Code is-:

package myprogram;

import javax.servlet.http.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.RequestDispatcher;

public class LoginPageServlet extends HttpServlet
{
    public void doGet(HttpServletRequest req,HttpServletResponse res) throws ServletException,IOException
    {
        res.setContentType("text/html");

        String fname=req.getParameter("p1");
        String lname=req.getParameter("p2");

        PrintWriter out=res.getWriter();

        out.println("HI from Login Page Servlet");
        out.println(fname);

        try{

        File file=new File("C://abc.xml");

        FileWriter fr=new FileWriter(file,true);

        BufferedWriter br=new BufferedWriter(fr);

        br.write("First Name" +fname + " Last name is " + lname);

        br.newLine();       

        out.println("File is created successfully");

        br.close();
        }

        catch(Exception e)
        {
            e.printStackTrace();

        }


    }


}
