I am creating cash counter application. i want to generate a pdf receipt in new window and print it.
I am using jsp to take input from user and servlets to process the input.
I am able to generate a pdf but in same page. i want it to be a popup menu. How to implement it?
@RequestMapping(value = { "/mapping" }, method = RequestMethod.GET)
@ResponseBody
public Map<A, List<B>> getAsByB(HttpServletRequest httpRequest) {
return map;
}
when i try to get it by url i get an error. how can i send a response of a map as a json ?
I have a SOAP Client with wsdl to send a query to a SOAP Server. Along with the SOAP response I am supposed to attach a generated csv file (Not required to open and read - just attach).
SOAP Handler has been implemented at server.
Since it is client code I am not supposed to paste the exact contents online.
I can create new SOAPMessage and use AttachmentPart to attach the file but I am stumped regarding where to set it as response. We have used only javax.xml and apache.cxf.
So I have basic java knowledge from 1st year of college and I wrote a program recently that sends keystrokes with the Robot class. Now I would like it to do the same but to send it to a window that isn't my active one.. I've searched and from what Ive found it seems like you cant do that in java, I need another language like C# (whick sux for me since i dont know any other then java).. Is this true? If not how would i send something to notepad for example while it is not the active window?
View Replies View RelatedInspite of not returning anything, what is the purpose of response object in servlet? I have typically used or heard of only response.sendRedirect()
View Replies View RelatedI have a requirement where a form is present with first name, last name, file upload etc. File upload is done through ajax call and then the form is submitted to a servlet. I want to know whether the file has been uploaded or not in the servlet which is called after i click on the form submit button. So is there any way i can read the response of the ajax call in the servlet ?
here is the ajax call below

I have a class that do a soap request to a web service , the response is containing a base64 string repressing a file content , how can i send this string to a servlet (maybe any other way) to send it to the user as a downloaded file .
View Replies View RelatedWhen do i get IllegalStateException in servlets.What it means by trying to write to the output stream (response) after the response has been committed by server. What it means by committing response and uncommitting response. cannot i send uncommitted response.

I have written a code to download .csv file with records from DB.
To download records i am uploading a .CSV file containing telephone number.
After downloading the .CSV file page is not getting refreshed.
Below is the code snippet i am using,where i am setting response content type as test/csv.
ServletOutputStream op = resp.getOutputStream();
// Set content type of output
resp.setContentType("text/csv");
resp.setHeader("Content-Disposition", "attachment; filename="test"");
op.flush();
op.close();
How that page will get refreshed after csv file download or after response.
I have to send a request with post parameters from one web application to another web application,both are running different servers.
In my application i don't have any JSP,html only controller part which will handle request extract request parameters & based on request params i'll do a web service call.
My current requirement is based on request parameters i'll send request to another web application with received parameters.
I tried with sendRedirect() ,but it support only get() method.
how to proceed further.
I'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?
I am learning few concepts in servlets. And i came across this doubt. We used to send data over network using httpsession as below.
HttpSession session = request.getSession();
Object obj = new Object();
session.setAttribute("object", obj);
And get the data in JSP with below code
<%= session.getAttribute("object")%>
However I am not sure whether HTTPSession is serializable or not.
How HTTPSession works?
I can now call the DB on the query I want and return results. What I know want to do is build an array of the data, forward it to the JSP page and display the bits individually.
So THis is the Servlet I havce:
package com.journaldev.jdbc.datasource;
import java.awt.List;
import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
[code]...
I think It is to do either with the way I am adding the values to User or its the forward:
getServletConfig().getServletContext().getRequestDispatcher("/test.jsp").forward(request, response);
I write a Client/Server program,trying to send and receive a object between client and server. I use the ObjectStream but there exists an EOFException on the client side when invoking readObject() .... I've tried many times but couldn't figure it out ...
server-side code
protected void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException, IOException {
try{
ObjectOutputStream out = new ObjectOutputStream(resp.getOutputStream());
ObjectInputStream in = new ObjectInputStream(req.getInputStream());
PersonalData pe = (PersonalData)in.readObject();
System.out.println(pe.getYearlySalary());
[Code] .....
I want to understand how is it possible to send data (image + text) along a single form. Here is my code:
<form method="post" action="updateAccount"
encType="multipart/form-data">
<input type="file" name="file" value="Select image ..." /> <input
type="submit" value="Start Upload" /> <br>
<textarea rows="8" cols="54" name="about">Yes
I would like to understand how does multipart/form-data works during file upload scenario's, Does it chunks the data from client to server while transferring the files ?
View Replies View RelatedI have a question in mind that this is my registration form. I am sending these values from HTML form to server and database. I have question that in my case if I click next to Add Another Mobile no in HTML.then a block is genereated and each time a new name is generated.
My Question is if I click 6 times then 6 name attribute are generated. How can I send and differentiate them on my server side.
Because at their I will use something request.getAttribute("Attr_Name");
But they are same. How to do this?.
I am new to javafx I start using it instead of swing i used the scene builder for my forms the problem i faced i don't know how to have main screen with menu bar at top and depending the select from the menu it will open other windows and those window must be inside my window just like for example netbeans.
I don't need to open new window in separate i need all windows inside my main window and controlling over them minimize maximize perhaps.
Gui java cash register
I have to make cash register system for saloon. it will look like this but I dont know how to do it.
Example : if customer come to make a hair cut. I will click on c button and choose her hair length then the price will come out. Each hair length will have different price. The customer will give the money and the total will show the customer money and the balance will come out after the total is deduct with the price.
I wrote this one all by myself (AND it works!!), but I know that to get really accurate results I need to use BigDecimal instead of Double. The problem is that I can't quite figure out how to do that. How to switch those out?
import java.util.Scanner;
public class CashReg
{
public static void main( String[] args )
{
Scanner userInput = new Scanner(System.in);
String due;
String tend;
[Code] .....
I have my own web application system now i want access a cash register machine from my web application to print receipt
View Replies View RelatedI'm writing this super simple code as I follow along in this java textbook, and I don't know why it's giving me an error in my tester program!
CashRegister.java
public class CashRegister //a cash register totals up sales and computes change due
{
private double purchase;
private double payment; /**establishes instance variables "purchase" and "payment" and assigns them as doubles to store the
two amounts later on. the assignment as private makes it so ONLY methods in this class can access
these instance variables*/
[Code] .....
We're told to make a cash register program for 5 products using Java. It loops until "-1" is entered on the "Continue?" input dialog box.There should be a:
1. Main Menu - where the user will pick what to buy (one product at a time) like the sample code below and prompt the user if he will buy another product or not. If yes, the program will go back to the main menu to buy another product and if not, continue to the program. And it looks something like this: LEvFOwQ.png
2. Receipt - at the end of every transaction.
3. Daily Sales Report where it shows all receipts then grand total like:
Transaction 1
-subtotal
Transaction 2
-subtotal
and so on then,
GRAND TOTAL
4. Inventory Report where it shows the Items Available before the Selling, Items Sold, and Items Available after Selling in table format.
Below is the code for a simple cash register for only one product that I made but I need to upgrade it for it to work for 5 products. That code will serve as the basis for this program.make the switch or if-else statement for the main menu first and if I got it right I try doing the rest.
int userQty1 = Integer.parseInt(JOptionPane.showInputDialog(
"Product ID Product Name Product Quantity Product Price"
+prodID1 + " " +prodName1 + " " + prodQty1 + " " +prodPrice1 "
"
+ and so on until prod5));

I am trying to create a slightly modified cash register. The user will enter the amount of the item, the payment received, calculate the change/refund, and then allow the user to choose the preferred bills.
import java.util.Scanner;
public class Register {
private static Scanner input;
public static void main(String[] args) {
input = new Scanner(System.in);
System.out.println("*****CASH REGISTER*****" );
System.out.print("Item Amount: " );
int amount = input.nextInt();
[Code] ....
I will try to clarify the code, to make things a little easier to interpret. in the refund method, I have set up a 2-d array to exist and function as an excel sheet. The refund amount is passed to the method and compared to each bill of the array. Once the refund is determined to be greater than a bill, the user is prompted to enter the preferred bill type. This is where my problem is...I would like the program to then calculate the number of bills and keep a tally of those bills in the 2nd column and then determine the new refund amount at which point the user will be prompted again to determine the desired bill.
Then print out the array of bills that are not equal to 0.
