Here is small piece of java code to generate binary stream which tells browser to save file as attachment. I believe that this code will help java beginners to understand HttpServletResponse of the Servlets.

package com.gaurangjadia.code.controllers;

import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.io.OutputStream;

import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class Download extends HttpServlet {

	private static final long serialVersionUID = 1L;

    public Download() {
        super();
    }

	public void init(ServletConfig config) throws ServletException {

	}

	protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

		try{
			String fileName = request.getParameter("name");
			String path = request.getSession().getServletContext().getRealPath("/WEB-INF/upload/");
			
			//strFileName: Name of the file which is being downloaded and which exist under /WEB-INF/upload/ path
			if(fileName.equals("strFileName")){
				path += "/" + fileName;

				File file = new File(path);
				Integer intFileLength = (int)(file.length() / 1024) + 1;

				response.setContentType(new MimetypesFileTypeMap().getContentType(file));
				response.setHeader("Content-Disposition", "attachment; filename=" + fileName);

				FileInputStream in = new FileInputStream(path);
				OutputStream out = response.getOutputStream();

				byte buf[] = new byte[intFileLength];
				int bytesRead = 0;

				while( (bytesRead = in.read(buf)) &gt; 0 ){
					out.write(buf, 0, bytesRead);
				}
				out.close();
				in.close();
			}
			else{
				request.getRequestDispatcher("/WEB-INF/download.jsp").forward(request, response);
			}
		}
		catch(Exception ex){
			request.getRequestDispatcher("/WEB-INF/download.jsp").forward(request, response);
		}
	}

	protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
		doGet(request, response);
	}

}
