Applet is not working in IE 5.0
Hello,
I've programmend a Applet which uses only Java 1.1 programming but it doesn't work in IE 5.0 with Opera 5.02 it works fine . Now somebody told me that I either need to install a plugin in IE 5.0 or look for a Java 1.1 Compiler. Is this wright ? Where can I find this old Compiler ?

If you're using a newer compiler, you can use the "-target 1.1" option to specify that the class files generated should work with a 1.1 version JVM. However, it is better to compile your code with JDK 1.1 if you will run it with a version 1.1 JRE -- that way, you don't use newer library features. You can get a version 1.1 compiler from the Products & APIs link on Sun's Java website.

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.
CarterOk. Thanks.

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 is not working and I do not know why it is not working

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.

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.
So I followed the instructions mentioned in
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:

hpYeah, after hours of searching it must be so that my son has a 8GB i.e. a 2G version and mine just happens to be the 3G as I bought mine a month later....did not know how to know the difference but now solved, thnx.

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:

Applet showDocument not working for local files!!
Hello:
I wrote a signed applet that is generates html files in user temp folder (for my Win 7: C:\Users\ren\AppData\Local\Temp\jTmp\ )
The applet is supposed to display the html files in browser by using showDocument().
I tested it on firefox 25 and IE9 enabling pop-up windows
However, it does nothing. Not even an exception.
The applet fails when running from web (but works in c:\)
For the case, it happens the same with oracle's sample: Displaying Documents in the Browser (The Java&trade; Tutorials &gt; Deployment &gt; Java …
In this applet, if you input a local file (file:///c:/ etc) , it won't open it.
I supposed showDocument was not subject to security restrictions, but seems the new rule is:
-applets running locally will display all pages (web/local)
-applets running from the web will display only web pages.
My applet used to work fine, but in some jre7 upgrade it was broken!!
Is this a bug or a new security issue?
Thanks in advance!Did you get this resolved..
I am using Internet Explorer v. 5.2 on Mac OS X v.10.2.8. I have successfully run an applet, using jre 1.3.1 which implements the "showDocument" method and opens a new page.
Could you post your code.. -
SetStartDate() and setEndDate() applet methods not working
I am Using setStartDate() and setEndDate() applet methods to set Start and End Date of my XACUTE output. But its not working.
document.<appletname>.getQueryObject().setStartDate(<Start Date>);
document.<appletname>.getQueryObject().setEndDate(<End Date >);
This is the part of the code i am using.Hi,
It seems you are trying with proper format following things i can suggest.
Check date time format which you are passing should be correct.
also you can try setParam(SD,StartDate) and setParam(ED,EndDate)
hope it helps!!

Applets does not work in Safari (IE,FF,Konqueror,Opera are OK) pls hlp
I have an applet on http://www.akropolis-uh.cz/html/_emptybody/hry_jimmalovani.html page
(it is czech site but is not important - applet is graphics only)
The page is XHTML 1.0 Strict and is valid.
Applet works in:
Firefox 2, 3
Internet explorer 5.5, 6, 7
Konqueror 3.5.x
Opera 9.5x
But in safari 3.3.1 (525.17) not run (on Windows platform ... behind proxy)
I think, there is a problem where safari loking for the main class (watch in java console).
I'v tried many changes ... moving to the same directory ... but nothing ...
The server use mod_rewrite but I'v tried many combination (including RewriteRule to same directory etc.).
Is there a bug in the html code ? any idea ?
I'm confused becouse only Safari is not working
Thank you 4 hlpI answer myself.
It is ok from diferent site without proxy and use Safari 3.1.2 (525.*21*).
Maybe there was a Safari/Proxy problem. :)
Sorry and thank you myself :) -
Applet is not working properly on windows 7 with java update 23
I am using applet in web application to serve as Image Viewer.
Problem Description :
1.Client machine configuration: Windows 7, java update 23 , IE8
2.When my web application is not secure (i.e. accessible via HTTP), applet is
able to download image from server.
3.But when my web application is secure (i.e. accessible via HTTPS), applet
is unable to download image from server.
4.When applet try to download image using HTTPS, somehow it takes it as
crossdomain access.
5.When Client machine has Windows vista or Windows xp OS no such problem
is there, applet works fine.
Note : Applet method to download image is called from javascript.
6.Java log console -

But this is only in Windows 7 machines. In Windows XP it is working fine.Windows 7 is much more fussy than XP about permissions. I can't make you investigate the Protocol relative URLs issue but surely it must be worth spending some time on it. -
We have about 1,800 workstations running Windows 7 (both 32-bit and 64-bit) running various versions of the Java JRE from 6 update 32 through 7 update 51. Most are on 6 update 45. We would like to standardize on Java 7 update 51 (32-bit) and get everyone updated to that version for security reasons.
For the past two weeks, we have been having trouble with our installation pre-pilot. What we are seeing is that our procedure successfully closes any open Internet Explorer windows and Java-related processes, uninstalls all old versions of the Java JRE, and then claims to have successfully installed Java 7 update 51. The Java Control panel works. We can even take Internet Explorer to Verify Java Version or Java Tester - What Version of Java Are You Running? and confirm that the Java applets on those sites are loading (though the latter only works after adding the site to the exceptions site list); however, when testers try to access our Kronos Workforce Central 6.3.10 system, the Java applets used by that system do not load.
We have tried the following things, none of which worked:
Clear Internet Explorer browser cache and cookies.
Clear the local Java cache.
Reboot the computer.
Reset Internet Explorer settings, including personal settings.
The one thing which does work is going into the Java Control Panel, going to the Security tab, unchecking "Enable Java content in the browser", pressing Apply, pressing OK on the pop-up window, checking the "Enable Java content in the browser" box again, pressing OK, pressing OK on the pop-up window, and then restarting Internet Explorer. It is only after this point that all Java applets, including the ones used by Kronos Workforce Central 6.3.10, work.
What I need to know is how I can automate the procedure of reinitializing the "Enable Java content in the browser" checkbox after installation or am I doing something wrong or missing a step in the automated installation that is causing this to happen?
We are using Microsoft SCCM 2007 R3 to accomplish this upgrade, and everything is being run on the client machine using the SYSTEM account. First, the PowerShell script "javaclean.ps1" is run, with part of the command-line process changing the PowerShell script execution policy to Bypass. This script handles the closing of Java-dependent applications and Java processes and uninstalls old Java versions.

Help on this issue would be much appreciated!It turns out that this is actually a problem with Kronos Workforce Central. We had the "site.java.plugin.CLSID.familyVersion" setting in that application set to "clsid:CAFEEFAC-0016-0000-FFFF-ABCDEFFEDCBA", which is the Java CLSID for Java 6. After updating this value to "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" (the Java universal CLSID), this problem did not occur upon the automatic upgrade of Java.
We have both Java 6 and Java 7 in our environment, and did during our Kronos implementation, so I don't know why we were using the Java 6 CLSID in the first place.

Java Applet HelloWorld "Getting Started With Applets" example not working
Hi there,
It's been ages since I ran my Linux CentOS boot of Linux but I am going through the official oracle java applet tutorials, just every time I try and run the "Hello World" applet in Firefox 17.0.3 and I am running the Iced Tea thing for java applets.
Every time I try and run the example from the following code:
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
import javax.swing.JLabel;
public class HelloWorld extends JApplet
// called when the user enters the html page:
public void init() // keep apps within the init() function very small as per the http://docs.oracle.com/javase/tutorial/deployment/applet/appletMethods.html
try{
SwingUtilities.invokeAndWait(new Runnable()
public void run()
JLabel myLabel = new JLabel("Hello World");
add(myLabel);
} // end running the application
}); //end of swing invokeand wait
} catch (Exception error){ // end user running the app in page
// System.err.println("GUI didn't work on initial run");
}It keeps bringing up the error "Start: Applet not initialized" I did google that basic error and from what I found I should consult the JavaConsole, I know the console was removed from the Firefox menu quite a while ago. So went to find a way of loading it using the IcedTea one but it keeps bringing up a load of errors in even trying to run that.
Is there anyway of sorting this out? I mean I have even tried installing the one on the oracle website, the plain JDK but nothing seems to work.
Is there anyone that can help me get applets working? I was even going to go as far as to reinstall my distro but I want to avoid that as much as possible.
Thanks and I look forward to any replies,
Jeremy.in the Getting Started with Java DB tutorial they
tell u how to set ur "DERBY_HOME" (what is that?).
once i press enter after typing this command:
set DERBY_HOME=D:\Java\Java
Phonebook\javadb in my command prompt do i get
any message or does it just go to the next line?type env or set or whatever in the command line to see what your environment variables are set to
they also tell u how to set ur "JAVA_HOME" (what is
that?). The Java installation you want to use
in their example they give u this: set
JAVA_HOME=C:\Program Files\Java\j2se1.4.2_05but in my java folder i have jdk1.6.0 and jre1.6.0
but no j2se1.4.2_05, so which 1 must i choose?It's up to you. I'd go with 1.6
also once ive done this: set
DERBY_HOME=D:\Java\Java Phonebook\javadb this
set JAVA_HOME=D:\Program
Files\Java\jre1.6.0 and this set
PATH=%DERBY_HOME%\bin;%PATH% and then type
sysinfo to verify that the variables were set
correctly i get these errors: 'D:\Java\Java' is
not recognized as an internal or external command,
operable program or batch file and '""'
is not recognized as an internal or external command,
operable program or batch file any help would
really be appreciated because this is really killing
me!you need to set your path variable - so something like:
set PATH=C:\Program Files\Java\j2se1.4.2_05\bin -

Applet showDocument() not working properly.
I'm having some problems with the showDocument(). Sometimes it works and sometimes it doesn't. It is very inconsistent and i can't seem to find the bug that is causing it. I would need to call the showDocument() function a few times (i added a refresh button calling the showDocument()) before it will finally show. The number of times i have to refresh is also not consistent.
Please help, thanks :)Did you get this resolved..
I am using Internet Explorer v. 5.2 on Mac OS X v.10.2.8. I have successfully run an applet, using jre 1.3.1 which implements the "showDocument" method and opens a new page.
Could you post your code..
