JavaFX applet JNLP not working in browser
Hi,
I have developed a JFX applet with multiple stages, which get visible and not visible at different times.
I have a search bar on the main stage which shows up at the beginning. However, on searching, i am not getting any response from the widget when i search.
I am running the jnlp in the browser.
I am doing the right thing ? Anything more needs to be done in terms of creating the jnlp ?

Perhaps you can make a simple mockup application illustrating how you do your stage management, so we can see how you do (if that's "the right thing"...).

Applet JNLP not accessible in browser ?
Hello,
I am new to java and to programiing in general. Thanks in advance for your help. I can't get an Applet to work in any browser (Google, Mozilla, IE) while it works fine in appletviewer. Why?
The Source:
import java.awt.*;
public class Hwa extends java.applet.Applet {
public void init (){
add(new Label("Hello World"));
compiled in Hwa.class, then in a Hwa.jar file,
The JNLP file:
<?xml version="1.0" encoding="UTF-8"?>
<jnlp spec="1.0+" codebase="" href="">
<information>
<title>Hw Applet</title>
<vendor>CCN</vendor>
</information>
<resources>
<j2se version="1.4+" href="http://java.sun.com/products/autodl/j2se" />
<jar href="http://www.ccca.eu/Hwa.jar" />
</resources>
</jnlp>
The HwaAPJNLP.html file:
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html dir="ltr" lang="fr"><head>
<meta content="text/html; charset=ISO-8859-1" http-equiv="content-type">
<title>CCCAEU</title>
<meta content="" name="author">
<style type="text/css"></style>
<link rel="stylesheet" href="CCCAEU.css" type="text/css">
</head><body>
<applet code="Hwa.class" ref_jnlp="Hwa.jnlp" height="50" width="150"></applet>
</body></html>
All files are copied on the http://ccca.eu/. of the server
Executing appletviewer HwaAPJNLP.html (local copy of the html file) works just fine BUT launching http://www.ccca.eu/HwaAPJNLP.html returns a blank rectangle with the JAVA console message "Detected from bootclasspath: C:\\PROGRA~1\\Java\\jre7\\lib\\deploy.jar" and "Incompatible magic value 1008812135 in class file Hwa". WHY ?
FYI, the ".htaccess" file on my WebServer is
AddType x-mapp-php5 .php
AddType application/x-java-jnlp-file JNLP
Thanks in advance for your support.Thank you Baftos. It works but I still do not understand the logic. Before, my Hwa.class was only accessible through my Hwa.jar file on http://www.ccca.eu/Hwa.jar, itself defined as the reference if the jnlp file, see above. My understanding of the jnlp logic is that the html page will load the Hwa.class from the Hwa.jar file. Is that correct ? Thanks to your post, I copied the Hwa.class directly under http://www.ccca.eu/Hwa.class and yes, when accessed through the browser, I can download it. Even better, my previous html page above - unchanged - now WORKS. Thanks for letting me know where I think wrong.

I am coding a video player in Netbeans 6.8. just find two problems:
1. the browser button not working in browser when I run the project from Netbeans under "run in browser" mode. however under "standard execution" mode, everything is fine.
2. can not run the jar file in the project's dist directory directly. in other word, I can not run the jar file outside of Netbeans.
I appreciate any help. thanks.

}thanks for your reply but I need more specific operation.
maybe I am not very clear about the problem one. I mean when I run the code in standard mode, if I click the browse button, a window will pop out and I can choose a video file from my local harddisk. but if I run it in "web start execution" mode and "run in browser" mode. the browse button make no response when I click it.

E72 - Ctrl+C and Ctrl+V not working in browser
yesterday i updated my nokia e72 mobile to latest firmware 31 , after that Ctrl+C and Ctrl+V and Ctrl+A shortcut keys are not working in browser. which have made me feel as bad as typing the same text again and again (usfel in blogging or web messaging).
ALthough these shortcut keys are working in notes and sms application, but not in browser and Quick office applications (word, ecxel etc).
Can some one tell , how to fix it. or do i need to wait for next firware update. firmware 31 was released on 31 of march 2010. and today is 26th of May. almost two months have passed, and nokia has not yet released patch for this bug ....
Nokia, how long i need to wait ?, for this bug fix release.(Had to edit because didn't read previous post clearly.)
I originally thought this was a problem of Quick office 6.2.217 Nokia_S603.2. I think it is a Nokia firmware problem as the previous post had stated. -
Web Cam applet is not working in great consistency
Hi... My video capturing applet is not working very well.
The image stream is displayed on the web page in JPEG format with 0.5 quality. However, it crashes after a while and the it does not release the vfw resource.
I have to restart my machine in order to execute it again.
Can anyone please help?
Thanks.

Applet does not work after conversion
Hi,
A have an html page on with a use an applet. The applet is downloaded in two cab files for the internet explorer.
The applet and the download works fine without the java plugin.
When I convert this page to using the html converter the applet does not work

Sombody any ideas,
Thank
Tom Van de VeldeI recently moved to programming applets and this problem gave me many
headaches. I know that the java compiler is supposed to compile with an
appropriate version, but I suspect that there may be a few flaws in the
system.
Try compiling with a command like this to force a 1.1 compilation:
"javac -target 1.1 yourfile.java"
This enabled my applets to load in Netscape 4.6, something they wouldn't do before.
Installing the java plugin seems to fix the problem on other browsers. This might
be a new bug introduced by Java 1.4, since I had very few problems with
Java 1.3...I dunno...that's speculation... -

Applet with Image not working in Browser, works fine in Appletviewer
Hi,
I encountered a problem , running my Applet in a browser. (IE and Firefox, ame problem).
When I use an ImageIcon, it doesnot work. in a browser.(When I remove the icon, it's oke)
In Appletviewer it works fine. In the browser I first got a security-exception.
I dealed with that by signing the jar (with the test certificate).
Now the browser's java console is not showin any faults, but the applet is showing no picture at all.
Only the text of the label is shown.
Can someone help me?
I downgraded the class to a very simple form, shown underneath. This runs fine in Appletviewer, but not in a Browser.
Best Regards
RemcoI have recently had the same problem, after lots of searching, I found that only Java 1.1 is supported by browsers, leaving out everything else including swing. So if you cant play the applet through your browser you need to download the appropriate patch i think about 5mbs.
You should find one at java.sun.com/getjava/download.html
Mine worked fine afterwards -
Applet work well in appletviewer but do not work within browser
hi, i created an applet that works well in appletviewer,but it does not work within a firefox browser, it issue a message: java.security.AccessControlException: access denied (java.io.FilePermission imgDir/vsam.jpg read). What can i do to solve this issue please ?
sign the applet, use doprivileged and trust the applet when you open it.
Use htmlconverter in jdk/bin folder to convert you applet so it uses
object tag instead of applet so IE won't try to run it with msjvm.
Signing applets:
http://forum.java.sun.com/thread.jsp?forum=63&thread=524815
second post and reply 18 for the java class file using doprivileged
Still problems?

Java Applet is not working in IE11 in win8/win 2008 server
Hi,
we have developed web application using PHP. in the start of the page we have link which will kick start the Java Applet application on click.
It is not working in IE 11 browser with all windows machine until we add that page in the compatibility view settings.
we have tried with many options like setting the meta tag in the start of the HTML page.
but this is also not helped. we expect some more idea/solution to solve this issue.
Thanks in Advance.
Thanks.
Udhayakumar Gururaj.IE 11 is not a supported browser of JavaFx. See http://www.oracle.com/technetwork/java/javafx/downloads/supportedconfigurations-1506746.html.
If you want Oracle to change their support policy, ask Oracle customer support.

Applet can not run in browser, but it wroks in appetviewer. Why?
I wrote a very simple applet, and it works well when I use appletviewer. But when I use browser to open the html file which contains the applet, it always gives no class found error. My browsers are IE5.0 and Netscape4.77. Hwo can I make the applet run in browser?
Quick response is greatly appreciated.see you have to put the proper code base in your html file.check if your browser is java enabled or not.Java plugin comes with IE 5 and it automatically get installed if you won't disagree with that.Check in optin menu of ur browser that java is enabled or not.
Applet works fine with all browser.
2nd thing when you r running applet through appletviewer,it runs as an application from your local JVM while running through browser means you are running applet through browser 's JVM. -
Enforcing JRE version for Applet does not work - 1.4.2
Hi,
Our application (Applet) requires JRE 1.4.2 .
I believe I need to use STATIC VERSIONING as we want the client desktop to ONLY use 1.4.2 for our applet.

http://java.sun.com/j2se/1.4.2/docs/guide/plugin/developer_guide/using_tags.html#in-ie
and
http://java.sun.com/products/plugin/versions.html
But for some reason the JAVA Installer fails to install the package.
It comes back with this pop-up error message:

Applet does not work with a proxy server.URgent
Hi,
I have an asp page being hosted from a IIS server.
The asp page has an applet which gets data from a server side component which is hosted as a service on the server side.For connection to the server I am using URLConnection object and trying to connect over a TCP connection.
The problem occurs when I use an proxy in the middle.
I have changed the browser settings to include the proxy.
The following is the error I recieve:

System.out.println("OPening input stream ");
// is = new DataInputStream(urlconnection.getInputStream());
System.out.println(urlconnection.getInputStream());
is = new DataInputStream(urlconnection.getInputStream());
The exact place where I get the error is whn i call URLConnection.openInputStream().
Usually this error comes with a malformed URL.But the same code words without a proxy.Also I am not making any changes to my code in both scenarios that is with or without proxy.
Please help.This is urgent and a showstopperThanks for your nice solution, but unfortunatelly it does not work with lines longer than 100 chars with Netscape. It works fine with IE and appletviewer too.
Example:
I use this code:
try {
URL url = new URL(protocol,hostName,portNumber,URLstring);
InputStream in = url.openStream();
BufferedInputStream bis = new BufferedInputStream(in);
StringBuffer input = new StringBuffer(60);
int c;
while ((c = bis.read()) != -1){
System.out.print((char)c);
input.append((char)c);
bis.close();
dataFromServer = input.toString();
catch(Exception ex) {
ex.printStackTrace();
}I use input file test.html with exactly 100 chars ('a')
Netscape Java Console:

Some browser links not working - any browser, but just on my mac
I have a strange issue. Over the last while certain page links on browser pages (which seem to be Java script links) won't work in any of my 5 browsers. If I put the same page in to any of my laptop's or my wife's browsers, the links work fine.
For example, I just tried to order some stuff via Staples, and whenever I tried to go to the next screen via a button, nothing happened. Even if I switched User Agents in Safari or Firefox, the "next" button didn't work. Same in Chrome, Camino, Flock and Opera on the same pages. I have noticed lots of drop down menus are not working properly either on many sites.
I figure some bit of OS code must be either blocking or misreading the instruction, but what?
Any ideas? Any input would be greatly appreciated!!errmm... i'm not sure why you are fiddling with java and system extensions...
java has nothing to do with javascript despite the name (you can blame sun for that) the javascript engine is an integral part of the browser not a separate extension.
Java on the other hand is an entirely separate entity and language that is independent of any one browser and is installed on the OS.
Javascript is commonly used in webpages (all most all these days) where as java is hardly used at all and is usually confined to little "applets" that run separately from the rest of the page.
If you suspect that it is something to do with your settings/preferences in your library then the easiest way to find out is by creating a new User account (go to system preferences> users> and add a user.) Then log into that account and try the browsers in there.
If you really think that it has something to do with system extensions then you can disable them by moving them out of the extensions directory (/System/Library/Extensions/) However i must stress that unless you know what you are doing and know what the extension does that you are moving to not do so... you can easily render your system unbootable if you move the wrong extension... unless you have installed a 3rd party system extension there shouldn't be anything in that directory that isn't meant to be there (this is a very different system from OS 9).
However there are internet plugins that may be interfering with your browsers, you can find these in /Library/Internet Plugins/ you can disable these by moving them also... the defaults are various flash, java, shockwave, quartz and quicktime files.

Connect JavaFx(Applets) to J2EE - best practice & browser session
Hi there,
Im new to JavaFX and Applet programming but highly interested.
What I dont get at the moment is how you connect the locally executed code of the applet to your system running on a server (J2EE).
Of course there seem to be different ways but I would like to avoid using RMI or things like that because of the problem with firewalls and proxies.
So I would like to prefer using HTTP(s) connection.
And here my questions:
1.) Is there any best practice around? For example: using HTTP because of the problems I mentioned above. Sample code for offering java method via HTTP?
2.) Is there a possibility to use the browser session? My J2EE applications are normally secured. If the user opens pages he has to login first and has than a valid session.
Can I use the applet in one of those pages and use the browser environment to connect? I dont want the user to input his credentials on every applet I provide. I would like to use the existing session.
Thanks in advance
Tom1) Yes. If you look at least at the numerous JavaFX official samples, you will find a number of them using HttpRequest to get data from various servers (Flickr, Amazon, Yahoo!, etc.). Actually, using HTTP quite insulates you from the kind of server: it doesn't matter if it run servlets or other Java EE stuff, PHP, Python or other. The applet only knows the HTTP API (GET and POST methods, perhaps some other REST stuff).
2) It is too long since I last did Java EE (was still J2EE...), so I can't help much, perhaps somebody will shed more light on the topic. If the Web page can use JavaScript to access this browser session, it can provide this information to the JavaFX applet (JS <-> JavaFX communication works as well as with Java applets).
