How to force browser to open/save/save as the file from server instead of browser cache.
I am creating a csv file through a pl/sql procedure and forwarding the link to user once user clicks on link he downloads the file, however if the same thing is repeated then browser returns the old cached file instead of new file generated on server.
Here my code . Iam trying to open text file in window_pane it will open when i click on save it will ask destination to save file if i save example like Read.txt it will save...when i go and check in that folder Read.txt file won't found...what is the error ....

import javax.swing.*; import javax.swing.filechooser.FileFilter; import javax.swing.filechooser.FileNameExtensionFilter; import java.io.*; import java.net.MalformedURLException; import java.awt.*; import java.awt.event.*; public class Read extends JFrame

I insert a link to a file, that you need to download. After I click the download button and that's performed this action. And how me save the file, where i chose?
private void actionAdd() { JFrame parentFrame = new JFrame(); JFileChooser fileChooser = new JFileChooser(); fileChooser.setDialogTitle("Specify a file to save"); URL verifiedUrl = verifyUrl(addTextField.getText());
I want it to save the names of the "Items" that were put into the "Cart" along with their retail prices and the subtotal of all of them, and the sales tax, and the final total, to a text file.
Main: package shoppingcartselection; import javax.swing.*; import java.util.ArrayList; public class Main { public static void main(String[] args)
This part of the code searches for every word in the text file and saves it to an ArrayList. It searches for the word if its valid of not.How can I offer a list of similar words when the word that the user inputs is not in the dictionary. Also I want it to prompt the user to accept the word or enter a replacement that gets saved in the dictionary.
New to programming. Am supposed to create a program that reads a text file (of integers) and computes a series of computations on these integers. I don't have the code for the integers in my code yet, (i know how to do those), but am struggling getting the array to simply print in the print writer. I have the user select a text file, read the file with a scanner, and then save the computations done from my code into another file. specifically, the problem is as follows: Write a program that uses a file chooser dialog to select a file containing some integers. The file contains an integer N followed by N integers. The program then uses a file chooser dialog to let the user specify the name and location of an output file to write results to.The data written to the output file will be as follows
(1) The original list of N numbers from the input file, (2) The original list of N numbers printed in reverse order of how they appear in the input file. (3) The sum and average of these numbers, (4) The minimum of all the numbers, (5) The maximum of all the numbers.
is my current exercise.so far i have gotten the code to create a file, and ask the user to input their age.what should i use to save what the user writes into the file?
Java Code:
package assignment7; import java.io.*; import java.util.*; public class Exercise2 { public static void main ( String [ ] args ) throws IOException { Scanner scan = new Scanner(System.in);
In our currenr project we have a requirement to open a local/network driver file/folder using JSF 2.0 <h:outputLink> in Firefox browser find the below sample code & correct it, how to achieve the above requirment

With my *nix command line I could "program file | tee savefile", but savefile holds the result of prior runs, gets read before I parse 'file', and this command line zero's out savefile before the program can read it.
The data is standard ASCII, I doubt I'll ever have 20k of data.

I am wondering how to do the following:when a user clicks on a save menu item, a save JFileChooser pops up. I would like to have a default file name set in the FileName box on the chooser, similar to what applications like Microsft word has. Right now, no file name will appear until the user has selected a file.I also need to know how to get the text from this box in the case that the user enters a new file name (the getSelection function is not useful here because the user will not have selected an existing file.)

I am wondering where the attributes I put into the Httpsession are stored.
For example, if I do the following HttpSession session = request.getSession(); session.setAttribute("usr", usr); session.setAttribute("pwd", pwd);
where does the ("pwd", pwd) pair store?
In my case, my web application needs to use the usr and pwd to login to another application, so I have to store them somewhere. So for security reason, if the pwd is kept in the browser side, I need to encrypt it first before I put it in the session. On the other hand if it is stored in the server memory then encryption seems not necessary
