I am trying to develop a app for facebook and other social networks using webview. When the app is closed all the cookies are removed and when it is relaunched we can't get use of cookies. I want to know how to store cookies permanently and use them when the browser is relaunched. And I also want to know how to save web history permanently.
View RepliesI am trying to use three cookies in a servlet to store the background and foreground color and text size but my code is not working for some reason. When I run the servlet I get an IndexOutOfBounds exception and in my code is says my cookies are not ever used, when they should be to store the variables?
package httpServlets;

I'm using WebView to display an OpenLayers3 map, e.g. Animation example from openlayers.org. When I lock my screen and unlock it, none of the openlayers layers are re-drawn. Sometimes bringing the window in to focus or a small resize of the component will cause the map to go blank. This doesn't occur in any browser I've tested, so it seems to be a WebView specific issue, although it also seems to be layer specific and possibly cache related. I've only tested on Windows, 1.7.0_51 x64 and 1.8.0_05 x64 ....
View Replies View RelatedI would like to reopen the following discussion: Show SVG-Image in WebView (JavaFX 8)
In our IDE (Eclipse Luna) running with jdk1.8.0_25 we load a html page into the webengine. The html page contains <img> tags with '.png' and '.svg' as src. Everything looks fine.
But if we execute the programm with java -jar, the WebEngine doesn't display the svg-files. Instead it shows the 'File not find'-Icon. The .png files still work
The files are definitly included into the jar and will be displayed if we link to them via <a href="someSvg.svg"></a>
So why it doesn't work.
I tried to print something using the new JavaFX 8 printing logic. Unfortunately, it does not work.
System:
Linux Mint 17x64
Oracle JDK 8u5
Default printer is cups pdf

import javafx.print.PrinterJob;
import javafx.scene.control.TextField;

Debugging shows the array MediaPrintableArea[] mpa at J2DPrinter:839 is missing its first element, which causes the exception at line 844.
If I execute
service.getSupportedAttributeValues(MediaPrintableArea.class, null, null)
instead of
service.getSupportedAttributeValues(MediaPrintableArea.class, null, pras)
I get an array with an element on the first position.
The msn object used for the PrintRequestAttributeSet is "iso-a4", which causes the missing first element in the MediaPrintableArea[] array.
So why does this happen? Am I missing some important config stuff? I tried to fix it myself, but I am not able to debug service.getSupportedAttributeValues(...).
I'm building app using Javafx Webview, but I have problems with running any Youtube video in Webview. The strange thing is that rarely it plays ok but more often it shows info "An error occurred, please try again later".
I tried to figure it out, so I made simple app using Youtube iframe API and firebug lite to show where is the problem:
Here is source of Main.java
Here is source of video.html
When I run it on my PC I see the result as below:
Error state 5 means "The requested content cannot be played in an HTML5 player or another error related to the HTML5 player has occurred.".
When I run this video.html file in firefox, chrome, or internal eclipse browser, everything is ok and always work.
I use JRE and JDK 1.8.20 but tried also with older versions, Windows 7 64 bit. I've also installed DivX - did not work. I tried on different PC (also win7 64 bit) and asked 2 people with similar config to run this - and it is not working. As far as I know there is everything ok on Mac.
I've run in an issue with connection timeout in the WebView. Requesting the URL in a browser will result in an answer, however it may take some time. Running the same request from the WebView results in a connection timeout.
What is the connection timeout for loading a page through the WebView (from issuing the request webEngine.load(url) to the state change failed passes about 40s). The Request in a browser takes about 10s.
Can I manipulate the underlying connection of the WebView (as suggested at java - How to connect to an HTTPS URL from a JavaFX application - Stack Overflow)
Can I set the connection timeout on the WebEngine/WebKit or per request?Is there an issue targeting this?Likewise I would be interested to get a handle on the connection so I can evaluate the header data to retrieve useful information (like response was a PDF which cannot be rendered in the WebView)....
I can't find an handler or a listener to intercept the 'Save as' window that should pops up when i click on a download link in a webview embedded page.
View Replies View RelatedI have a WebView which displays a site. At a specific page I want to fill in some values into <input> elements. So i use such an event handler (browser is of WebView class)
browser.addEventHandler(MouseEvent.MOUSE_CLICKED,
new EventHandler<MouseEvent>(){
public void handle(MouseEvent e) {
Document doc = webEngine.getDocument();
if (doc == null) {
System.out.println("Doc is null");
[Code] ....
The handler sets the "value" but view doesn't reflect that, field is empty.
I have a big issue to render this html page with the webview component :
<html><head lang="en"> <meta charset="UTF-8"> <title>Pb Rotate</title> <style type="text/css"> #myDivRotate {
color: purple; background-color: #d8da3d; height: 200px; width: 300px; margin-top: 20px; margin-left:20px; -webkit-transform:perspective(400px) rotateX(30deg); -webkit-backface-visibility: visible; }
</style></head><body> <div id="myDivRotate"> Coucou
</div></body></html>
The problem is from "perspective" in -webkit-transform. Without it's ok. But with this one, the result is different from a standard browser like chrome or safari.
I have a WebView and a Javascript that appends an <img> tag in a webview.
Like so:
function insertImg(src) {
$("body").append("<img src='" + src + "'/>");
}
I call this function with the following code:
String path = "file://Users/rod/Desktop/123.gif";
webengine.executeScript("insertImg('" + path + "')");
However, this does not work and no image is displayed.
How can this be achieved?
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 am using servlet 2.4 I used the ff. code below to set httponly in my application's cookies but it did not work. When I do a javascrip alert (document. cooke) in my page, the session id still shows up.
Cookie [] cookies = request.getCookies();
for(int x=0; x<cookies.length; x++){
Cookie cookie = (Cookie) cookies[x];
String cookieValue = cookie.getValue();
cookie.setValue(cookieValue + "; HttpOnly");
}
I also tried doing this and it wouldn't work too
String sessionid = request.getSession().getId();
response.setHeader("SET-COOKIE", "JSESSIONID=" + sessionid + "; HttpOnly");
by the way I am using an application server with its JAVA EE version = 1.4 and JAVA SE version = 5

Hello World program. We had to build it. Write a basic Java program that will implement one class to store a state of a project. The class should have one property to store a textual name of the state. When a object of this class is created the initial state should be "Open".
1) Class should have one method next() which will move the project to the next step in the sequence: Open - In progress - Closed.If next method is called for a project in the Closed state it should do nothing.
2) Class should have a method close() which will move the project into the Closed state.
3) Class should have a method print() that will output a current state of the project.

I have been working on this thing for almost a week, and really don't have a clue on what to do. I know I have to use a string = open, and I know I have to create an object. I don't have a clue on how to do this. I have read the chapter so many times, I almost memorized it, but what he wants is nothing like our demo in the book. the Book used set and get, and utility scanner, but he doesn't want any of that. Just a basic code that will move from Open --- in progress --- closed.
The best I can tell what he wants is when I set the object to open it will display " project is open", then when I set it to " in progress" it will read project is "in progress". I don't have a clue what close is suppose to do, or the print method.

Then I want to Let them know if they are correct or not and have a choice to play as many times as they like. When they no longer want to play,I want to let them know how many they got correct and how many incorrect. I am not sure which would be better a hash map or 2d array and dont know where to start with each.

I have a java query like this
query ="Select major_career.Major_Title, career.ISCOTitle,career.FS.... " //only partial,
// I swear the query is correct
resultSet = statement.executeQuery(query); //this executes it
relArr = new ArrayList<String>(); //don't worry it is intialized
In the code below I tried to store the resultset components into the arraylist
int j = 1;
while (resultSet.next()) {
while(j<=numberOfColumns){
relArr.add(resultSet.getObject(j).toString());
j++;
}
} // end while
I am not sure whether the arraylist is able to store the result set because when i try to display it like show below it only shows some rows and only the first column
Iterator it = relArr.iterator();
while (it.hasNext())
{
System.out.println(it.next());
I want to manipulate the resultset results in my program by copying the resultset values to other datastructures.
