View Replies View RelatedServlets :: How To Send Json Data From A Server
Aug 11, 2014I'm new to json and the web. My purpose is to use json data from a server and parse it and show meaningful data to the user. I am aware of json parsing, so no sweat there. However, I would like to know how json data is sent to the front end after which it can be parsed.
Usually in my json parsing examples, I have a variable like var data = ]OR I do a getJSON on a data.json file which I have stored in the project folder. However, I want this data to come real time from a servlet. How to go about this?
So, basically my question is, how do I send real time json data from a servlet backend, say some records which I have extracted from the database using jdbc?
Swing/AWT/SWT :: Saving And Loading Data Of Jtable
Apr 6, 2015I am trying to make a program where a user can enter guests name for a hotel, the JTable includes rows for the name of the tenant, the room number, month etc.
I've made the table, however I am having some trouble in saving the data that I put into the table. I used jtextfield and a jbutton to but data into the jtable. I am trying to save the data, and load it just buy clicking a button.
table.setModel(new DefaultTableModel(
new Object[][] {
},
new String[] {
"Room", "Name", "Month", "Payment"//table rows
}
));
This is my basic table. And what I'm trying to do to save the data is:
DefaultTableModel model = new DefaultTableModel();
private JFileChooser myJFileChooser = new JFileChooser(new File("."));
private void saveTable() {
if (myJFileChooser.showSaveDialog(null) ==
JFileChooser.APPROVE_OPTION ) {
saveTable(myJFileChooser.getSelectedFile());
[Code] ....
When I run my program, I'm able to click on a button, and the dialog box will appear, I'm also able to save the data to a file. However when I click on the retieve data button I made the dialog box opens, the file is there, however when I click it, nothing happens.

Unable To Retrieve Information From JSON Repository Stored Online
Feb 25, 2015I'm trying to retrieve information from a json repository stored online. I have so far setup my code to create the string that could be used as the url. What I'm not sure about is how you setup a Json Parser?
- Would you recommend I use a library? I hear google-gson is meant to be good?
- How easy is it to convert a string into a URL? I assumed that this would be good enough
" String searchURL = "randomURL.com"
URL temp = new URL(searchURL);" ,
but I get a MalformedURLException.
- What do I need to know to use JSON?

Images Not Loading
Nov 15, 2011I usually code in PHP, C++ and ActionScript.I'm trying to follow an example of how to add images to a full screen application. What he does is that he adds a JPG background image, and then 4 PNG images. I tried to do it like I always do, by writing the code by myself looking at the book. It didn't work. I searched for errors in the code, changed some things, tried different things, but it didn't work. Then I tried to use his own code, that I downloaded from his website. That didn't work either.. I tried to find another way to add an image, and I can't seem to figure out a way to implement images in any other way into this class that's written in this book.. My Java programming level isn't just high enough.
Here's the code for the file where the images load, downloaded from the authors website (I've modified the brackets and some spaces so that it becomes easier to read):
Java Code:
import java.awt.*;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class ImageTest extends JFrame {
public static void main(String[] args) {
DisplayMode displayMode;
[code]....
Loading File From Input
Mar 24, 2015how I can change my code so that somebody can actually input the specified file path, rather than having it fixed in the code. I previously used
Scanner in = new Scanner(System.in);
System.out.println("What is the filename?");
String input = in.nextLine();
File file = new File(input);
But then the program would not display the frequencies.
import java.io.File;
import java.util.*;
/*
This program will allow the user to enter in a text file name, when prompted the program will anaylser the text and display the frequencies
*/
public class AssP {
public static void main(String[] args ) {
Scanner scan;
try {
Scanner scanner = scan = new Scanner(new File("C:/Users/Mary/workspace/Assingment/src/test.txt"));
[code]....
This is my current code and I need to so the user can load their own files.
