JSP :: Cancel Button Behaves Differently In Chrome And In Firefox
Feb 25, 2014
My current URL is URL....The context rootpath is URL....In my current URL page, I upload a CSV file. This page has two buttons-- ok and Cancel and these buttons are what I'm having trouble with ( I will come to that part in a short while). The relevant JSP part is as follows.
<html:form action="importEmployee?method=save" method="POST" styleId="importEmployee" enctype="multipart/form-data">
....... some headers and title bar and stuff... and then as follows.
<div class="contentSection">
<table border="0" class="formTable">
<html:hidden property = "selectedSet" />
<tr>
[code]...
So, if I click on cancel in the second URLpage (URL...), I go back to the first URLpage, i.e to URL...But this part behaves differently in Firefox and in Chrome browsers.In Chrome, if I click on cancel in the second page, I can still see the uploaded file name( the hidden property in the first JSP is the file name ) in the first page. And if I click on ok, I can do the processing again as was done by clicking ok the first time on the first page.However when I run my application in a Firefox browser, if I click on cancel in the second page, the uploaded file name says 'no file selected' in the first page. Hence to import Employees again, I need to upload a new/same CSV file again.
I don't want the file to be present in the first page when I click on cancel in the second page even when I run my application in Chrome. Yes, I require the file name to be a hidden property. This is because depending on the data in the file, different kind of processings are done and some of them require to take additional inputs from user on another page and a third page does the processing. So the file name should be passed on to the form but I don't want the user to upload the file again.
However in the event the user clicks on cancel, I don't want the file name to be retained in the first page. But this isn't happening.So I have two questions. Why is the behaviour different in Chrome and in Firefox and is there a way I can correct the way it behaves in chrome?

Okay i have done some research and have found that when using the JOptionPane, when the cancel or x button is clicked, the value is returned as null for the particular JOptionPane. It does not seem to work when I try to code it though, I have tried the following:
Java Code:
public static int getBoardType()
{
int boardType = 0;
String boardInput;
boardInput = JOptionPane.showInputDialog(null,
"Enter 1 (LongBoard), 2 (Shortboard), or 3 (BoogieBoard)." ,
"Dwelling Type",
JOptionPane.QUESTION_MESSAGE);
[Code] ....
If the "X" button or the Cancel button does in fact return a null value, why is the way I have this set up not working?

I have a little application that I made, it requires that I save data to a file in data/coins.cdp. When I run the application with java myProg in the terminal everything is correct, when I create the executable jar and run java -jar myJar.jar or ./myjar.jar everything also works. Even if I copy the jar to a different location, and run it through the terminal, it still works fine. Things get weird through when I copy the jar to a new location and double click on it, because then no folder gets created and no file is written.
Why is that?

Here is my code. Obviously this doesn't do a lot but that's only because I abstracted out the problem so there are not many lines to decipher.
Java Code:
import java.util.Scanner;
class threadOne extends threadTwo {
public static void main(String[] args) {
threadTwo threadTwoObj = new threadTwo();
threadTwoObj.start();
while (!userInput.equals("exit")) {
[Code] ....
What its supposed to do: When the user returns "exit" in the console it is supposed to break out of both while loops in both threads.
What it actually does: breaks out of the while loop in threadOne and not in threadTwo.
Basically the idea is to have a thread running doing computation and another thread able to query it for updates or interact to make changes to the flow. This will be useful, among other ways, for the sorts of problems where finding a solution is easy but where a better solution can always be found with more time. So for example finding directions on a map. Its easy to find a solution, but if you search longer you can find a faster route, if you search longer still than faster still.

Can we cance/stop a long running database query execution instantly so that we can do any another task.
As i know swing uses a single thread i,e Event Dispatch Thread (EDT), But at the same time we can use Swingworker class for better use of UI. When we use Swingworker class the process goes to a different thread and our basic UI is not Frozen. Infact we can do another task. But what I want is I want to stop of cancel the execution of swingworker thread ( Because I that thread takes long time to execute). How can I do that??
I used ProgressMonitor and in the cancel option i canceled the task ( worker.cancel(true) also i closed the connection and statement for executing the database query using stmt.close() and conn.close() methods.
But it does not work. How to cancel a long running database background process in a Java Swing Program.

I use Chrome rather than IE. Recently I got an error message when I tried to deposit a check online.
It said that I needed up get a newer version of Java than 6.10, so I downloaded 7u51.
When I tried to deposit the check again, Chrome asked if I wanted to run the app, and I said yes, but that took me back to the download link again.
I spent almost an hour with my bank experts, but they were unable to solve the problem.
When we tried it on Internet Explorer, it worked fine.
Later, I discovered that on the Java Control Panel under the Default Browser for Java, it has only IE and Mozilla, with the IE being checked and greyed out.
I'm assuming that's why the problems on Chrome, even though up until a few days ago, I was able to deposit checks using Chrome-Java.

I have a jsf form which has a drop down. When I select any value in drop down it shows related details. When I use chrome browser, and I press back space key it comes back to the page, it keeps the value selected which was selected earlier, but in the firefox, IE it keeps the zero index selected. The same code is not working for chrome browser.
I would like the zero index to be selected in the drop down in previous page in chrome browser also when back space key is pressed...

I have a simple application ( only 2 JSPs files and one servlet the main components the whole webapp directory is attached ), I am using security constraint to redirect the user to HTTPS instead of HTTP when he submit from first page to the second page.
The problem is when the user submit the first page I get the error HTTP Status 405 - HTTP method GET is not supported by this URL although I m using only POST.
I have traced the firefox browser using httpfox and the result was the first HTTP request was done using POST correctly but after redirect the browser send GET.
This problem appears with FireFOx and IE but doesnot appear with google chrome.
index.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="myTags" tagdir="/WEB-INF/tags" %>
<html>

<title>Welcome Page</title>
<link href="css/style.css" type = "text/css" rel="stylesheet" />

I'm experimenting the basic concepts of Servlet technology with my below simple setup.
I have a welcome.jsp defined under webContent in eclipse and my welcome.jsp looks like
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1" [b]session="false"[/b]%>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
[Code] ....
Now I have few questions based on the above setup
1) As you see session="false" in jsp, and when I used scriptlet like <%= request.getSession(false) %>, I see "null" being printed but if I use pageContext.request.session.id, the session is not null. How does session = "false" influences scriptlets and implicit objects and why the behavior is different
2) If session really exists, even when session=false is used, when I disabled cookies in FireFox browser and click on "click Me" hyperlink, the control goes to Controller, but in the servlet, I see 'No Session Created" being displayed. Which means session was not created and probably because I used false is getSession(false). But if I enable cookies, with the same setup, I get Session ID = << some value>> being printed and this is same as the session what printed through pageContext.request.session.id in the jsp.
So when cookies disabled, how can pageContext.request.session.id actually printed session id , but not in servlet and when cookies enabled, the same session id is displayed in both cases.
My question is why there is no impact in jsp, when cookies are disabled.

I have written sample web application with servlets and jsp. As per the below code the action url should be executed automatically according to the "onload". I have written this below code in one of my servlet, The below "onload" form hits the path in action only in Firefox and IE but not in Chrome(41.0.2272.74 beta-m (64-bit)).I have seen the link [Chrome - <body onload=“”> is not working ][1] , I have my below code in the end of servelt. there is nothing to execute after this code in the servlet.
out.write("<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
");
out.write("<html><body onload="alert('alert has been fired');document.forms[0].submit()">
");
out.write("<form method="POST" action="" + actionUrl + "">
[Code] ....
Is there any reserved key words of chrome in the above action url? If I execute this code in the html format, it is working in chrome. but if it is from servlet, alert() is not running.

The gist of it is to create a very basic memory game. There are 12 buttons, each associated with an icon. Every button that you click will display the icon and will stay there until clicked again. I got the bulk of it taken care of, but my issue lies with switching the icons back and forth. I can get them to display one at a time, but when I click on a new button, all the icons except the button I just clicked don't display. Essentially, only one shows up at a time.

I am creating a mad libs type program. This section of code is for the user to be able to make their own mad lib template (that people will be able to fill out later). The normal blanks in a mad lib are for verb, noun, adjective, adverb, etc. I cam up with 13 or so of these buttons, but it would be nice that if the user wants to add a button that they think we missed, such as 'Person in the Room' or 'Silly Location'...that the user would be able to do this. I sort of pictured there being a button that says 'add button' or something like that. Is there a ways to do this with the way I've set things up?
public class MadLibs {
public static void main(String[] args) throws IOException {
////////////////////
//TEXT PANE WINDOW//
////////////////////
//Set up a JTextPane object : The JTextPane is a specialized form of the JEditorPane
//designed especially for the editing (and display) of styled text.
final JTextPane pane = new JTextPane();
