Java applet faild
I try to open a web page and i get this message in the status bar :
java applet failed
dominoactionbar notinited
where can i find a plug in or something like that so i can properly view the web page?
i was having the same problem
i used to get message:
dominoactionbar notinited
but i solved it. first i installed MVM(microsoft vertual Mechine) I found an installable version of msjvm for XP (msjavx86.exe)searching on internet(5.5MB). after installing re-start. then
I have gone to
Tools-Internet Options-Advanced-Microsoft VM -enable all options. and disable all option under SUN(java).etc. I enabled only Microsoft VM.
restart computer. it really working

Hello,
I have a customer that is looking to set up SSO with an application that uses a Java Applet as its login screen to the app.
Any advice on how this can be set up. SSO via External Application doesn't seem to work since it doesn't use a GET or POST method.
Thank You!
PadminiAn applet (with normal security setup) can only open up socket connections to the host from whence the applet came. Sounds like your applet is trying to talk to port 5000 on the client's box. Can't do that, unless:
a) The client's box is the server (which is the case under your first scenario)
b) The applet is signed or otherwise set up to be "trusted" that it doesn't contain harmful code.
The security policy is there for a reason. I, for example, wouldn't want to stumble across some rogue applet out on the internet which then tries to open up socket connections to things on my corporate intranet or local machine -- unless I KNEW it was going to do that (I "trust" it). -
Can I save as pdf when printing from a Java applet on a webpage in Safari?
I am trying to use a webpage that is running a Java applet. A dialog comes up that asks me, "Do you want to run this application?" The dialog also says, "This application will run with limited access that is intended to protect your computer and personal information." I select "Run". The applet generates an image I want to print. There is a "Print" button on the applet. I select "Print". A Security Warning dialog comes up that says, "The applet has requested access to the printer. Do you want to allow this action?" I select "OK". The Print dialog comes up. I choose the PDF button in the lower left corner. I choose "Save as PDF...". A second Print dialog comes up. I input a title in the Save As box. I choose Desktop in the Where box. I do not change anything else and select the "Save" button. A dialog appears that says, "Print Error while printing." There is an icon with paper, a pencil, a ruler and a paintbrush on the dialog.
Is this an issue with Apple and Java security? Does "run with limited access" mean I can't print and save as PDF? Should I upgrade to Mavericks? It seems like others have not been happy with Mavericks and have had problems saving as PDF with Mavericks. How do I let Apple know about this error? The error dialog is useless.
I am on a Mac running OS X 10.8.5 and Safari 6.1.2. My Java version is 7 update 51.
What other information can I provide to help solve the problem (if it can be solved)?
Thank you for your help!Correction I would like to save as PDF/A-1b
for archiving.

Problem Launching Java Applet with Plug-in: Version 1.4.2_01
Hello out there:
I recently installed j2re-1.4.2_01 on my home computer but have been unable to access Web sites emmploying JAva applets. The following is an email exchange with Jeff Hall of Lowell Observatory, manager of an educational site hosted by Lowell, trying to resolve my problem. The messages are better understood if read in reverse order.
I'm hoping that someone will recognize the source of my problem and can recommmend a solution. I would appreciate any help offered.
Thanks,
Mike Coucke
Hi Jeff:
Well, I guess the problem lies with me somewhere. Here's my answer/status to your questions/suggestions:
1) I'm using MS Windows Me version 4.90.3000
2) I do have the directory C:\Windows\.jpi_cache\jar\, but the only thing in it is an empty folder labeled "1.0". The file LP.jar does not exist anywhere on my hard drive.
3) I tried several game sites that utilized Java applets and got the same results: the Java cup in the upper left corner followed a few seconds later by the red "X". So, evidently the problem is somewhere on my end.
I'm going to post our email exchanges in a Java Users Forum managed by Sun to see if anyone out there can solve my problem. However, if you have any more suggestions, I'll be glad to try them.
Thanks for the help.

Mike,
Rats! What version of Windows are you using? It's a little strange to
see the user directory set to C:\Windows; if you're using XP, I'd expect
it to be something like C:\Documents and Settings\Mike Coucke. In any
event, the output that is of concern is these two lines:
java.lang.ClassNotFoundException: LPRemote.class
Caused by: java.net.UnknownHostException: proxy
It looks like your browser is not finding our server's IP when it comes
time to download the necessary Java code.
LPRemote.class is the fundamental code that runs LOPARC, and your
browser should be downloading it automatically when you click connect.
LPRemote.class is stored along with a bunch of other classes in a file
called "LP.jar" that you download from our server. So, if you go to C:
in Windows Explorer and do a file search for LP.jar, you should find it.
On my machine, it's stored in a directory called ".jpi_cache\jar\" in my
user home directory. Let me know if you have this file, or the
jpi-cache directory.
One other thing you might try is going to a different site that you know
uses Java applets -- I think some of the online game rooms at Yahoo use
Java. See if other sites that use Java load correctly. Then we'll know
if it's our server specifically, or a more general problem on your end.

Hello Jeff:
I still have the Java "blues". I followed your instructions, but am still unable to launch a LOPARC session. After an initial failure, I uninstalled all three Java versions I had (1.4.0, 1.4.1, 1.4.2), then reinstalled 1.4.2_01 from the Sun website.
Now, when I try to launch LOPARC, I initially get a blank window with the Java cup in the upper left corner. After about 20 seconds, the cup changes to a red "X". During those 20 seconds, the following appear in the IE message bar at the bottom of the window: "Applet LPRemote notinited" (their spelling) which changes to "Loading Java Applet Failed..." when the red "X" appears.
Following is a copy of the log from my Java Console during all of this:

Hi Mike,
Try it now. I think this problem has arisen because Sun just
released a new version of the Plug-in (1.4.2), and when we released the
public beta of LOPARC, only one relevant version (1.4.0) was available
and the LOPARC code was written to look for that by default. I have
just recoded the relevant routines so they should now cause your browser
to simply pick up the latest 1.4 version of the Plug-in you have
installed, whatever it is. I "broke" Java on my machine to replicate
your problem, and the code I inserted today did fix it. Hopefully it
will have the same effect for you. I am running IE 6 and plugin
1.4.2_01 (as accessed via Tools->Sun Java Console).
One broader problem: some (non-LOPARC-specific) users on the Sun
forums have reported the "JRE collision" you are seeing when multiple
versions of the Plug-in are installed on the same machine. So if the
fix I made to our code doesn't work, one option would be to uninstall
all Java components from your computer and do a fresh install of the
latest runtime environment.
Let me know how/if this works. Thanks for the feedback and for your
patience.
Best regards,
Jeff Hall

Hello Jeff:
So far, I have been unable to launch a LOPARC session. I repeatedly

My browser is MS Internet Explorer version 6.0.2800.1106 Initially I was
using Java Plug-In version 1.4.1 and received the error message. I went
to the Sun website and downloaded/installed Java Plug-In version 1.4.2
and still get the message.
Before I try to launch LOPARC, I can select Tools->Sun Java Console from
IE's pull down menu to check my Java Plug-In version. When I try to

Dear Michael Coucke:
Thank you for registering with Lowell Observatory's online education
site. We hope you enjoy using it and visit regularly as we continue to
expand its features and capabilities. This is a one-time welcoming
email.
For your records, your user ID is xxxxx, and your password is #########.
You'll need to supply these each time you log in.
This site gives you access to research-grade equipment including a 16"
telescope, CCD detector, and image processing software. Our online
archive of data is now available 24/7. The telescope will be opening to
our onsite users in May, and on select nights to the Internet at large
in June.
We have designed this site so you don't need a huge monitor or a
supercomputer to use it. All pages are viewable on screens running at
800x600 resolution or higher. To use LOPARC, you'll need a Java-enabled
browser with the Java 1.4 plug-in installed. If you don't have the
plug-in, you'll be prompted to download it the first time you attempt to
connect. This is an admittedly large (9 MB) but one-time-only download.
This site works correctly under Internet Explorer version 5 or higher.
If you use Netscape, you must be running version 6 or higher, and
display or applet behavior anomalies may occur.
If at any time you can't connect to our server, simply try again later.
We do experience several power outages each year, particularly during
Flagstaff's summer thunderstorm season. Our server is fully protected
and backed up, and can be quickly brought back on line, but any active
user sessions will be lost. Thanks for your patience during these
inevitable downtimes.
Your questions, comments, suggestions, and bug reports about this site
are always welcome. On behalf of the LOPARC development team, thanks
for signing up!

I just helped my Dad set up his computer with a new

access any secure Web sites. The cable folks had us
disable the proxy. It looks like the error message is
saying it can't find your proxy server, and the logs
you posted say that you've decided to configure your
proxy manually, rather than using the settings from
IE (which is how mine is set up in the plugin
control panel.)
Could that be the problem?

I am trying to use and education program that needs Java applets and it will not run on Safari. IE will not install from the web. How do I get a browser that will work to install so I can use this program when I travel.
Try using FireFox. IE will only run on a Mac if you run Windows on the Mac.
Windows on Intel Macs
There are presently several alternatives for running Windows on Intel Macs.
Install the Apple Boot Camp software. Purchase Windows 7 or Windows 8. Follow instructions in the Boot Camp documentation on installation of Boot Camp, creating Driver CD, and installing Windows. Boot Camp enables you to boot the computer into OS X or Windows.
Parallels Desktop for Mac and Windows XP, Vista Business, Vista Ultimate, or Windows 7. Parallels is software virtualization that enables running Windows concurrently with OS X.
VM Fusion and Windows XP, Vista Business, Vista Ultimate, or Windows 7. VM Fusion is software virtualization that enables running Windows concurrently with OS X.
CrossOver which enables running many Windows applications without having to install Windows. The Windows applications can run concurrently with OS X.
VirtualBox is a new Open Source freeware virtual machine such as VM Fusion and Parallels that was developed by Solaris. It is not as fully developed for the Mac as Parallels and VM Fusion.
Note that Parallels and VM Fusion can also run other operating systems such as Linux, Unix, OS/2, Solaris, etc. There are performance differences between dual-boot systems and virtualization. The latter tend to be a little slower (not much) and do not provide the video performance of the dual-boot system. See MacTech.com's Virtualization Benchmarking for comparisons of Boot Camp, Parallels, and VM Fusion. A more recent comparison of Parallels, VM Fusion, and Virtual Box is found at Virtualization Benchmarks- Parallels 10 vs. Fusion 7 vs. VirtualBox. Boot Camp is only available with Leopard and later. Except for Crossover and a couple of similar alternatives like DarWine you must have a valid installer disc for Windows.
You must also have an internal optical drive for installing Windows. Windows cannot be installed from an external optical drive. -
Problem with java applet and array of arrays
hi!
i'm passing an array of arrays from java applet using
JSObject.getWindow(applet).call("jsFunction", array(array(), array()) );
in every other browser than safari 4.0.2 it's no problem to iterate over this array. in safari "array.length" is undefined. is such construction supported in safari's js engine?

The method waiting a ArrayofAlicIva, but if i define this object is not posible to set the object inside the array because the wsdl not have this functions.
I need to define array of objects but the object is inside is the diferent type of array.
If i Define the array of object correct to object inside, the method expect that the other array type.
Is a Deadlock ??
The solution in Java is Simple
AlicIva[] alicIva = new AlicIva[1];
alicIva[0]= new AlicIva();
alicIva[0].setId(Short.parseShort(1));
fedr[0].setIva(alicIva);
this is the method imported in java class to form

Removing the 'Warning Java Applet' Status Bar
Hi,
I've written an applet that does not require access outside the sandbox so doesn't need signing. However, it pops up an instance of Window, and because it's not signed the window has a status bar across the bottom which says 'Warning Java Applet' or something similar depending on the browser. Is there any way to remove this status bar without signing the applet or changing the security settings of the browser. I guess it must be added to the window so maybe it's just a component that can be removed, but how?
Thanks in advanceToday the Security Warning sign appeared at the bottom of my computer screen - how do I get rid of it. I do have Java whose icon used to be in the lower right hand section of my screen - along with all the other icon programs that I have.
Now the icon is no longer down on the bottom right of the screen, but in the middle with a Security Warning -(the wording) next to the jave icon.
This is really annoying me - how can I get rid of it, and - why did it appear here?
Anxiously awaiting your reply.

Java Control Panel wont open at all and any Java Applets crash web browsers
Hello,
I recently installed a fresh fully updated copy of Windows 7 Home Premium 64 bit, and I have not for the life of me been able to get Java working at all. Java version is the latest JRE 6U31. I only have Internet Explorer 9 installed but I doubt it is a browser issue since I cannot even open the Java control panel. I have tried using the 32 bit version of Java, and the 64 bit. Anytime I try to open the Java control panel with either 32 bit or 64 bit, I get an error message (click link below to view error message):

I can only bring up the Java Control Panel using the command “javaws –viewer” . Anytime I try to load a web page with a Java applet in either 64 bit or 32 bit, it freezes and crashes. I am running Internet Explorer 9 and have tried both the 32 bit and 64 bit browser versions. I saw Java’s recommendation to only use the 32 bit version so I have mainly been trying to get the 32 bit version working 1st, with no success. I have tried ALL of the following steps, and have done some exhaustive research on this problem. It seems others have had this issue as well, with no solution to be found:
• Uninstalled and reinstalled only Java 32 bit JRE 6u31 multiple times (Used Javara and reg cleaner to remove all old Java traces)
• Uninstalled and reinstalled only Java 64 bit JRE 6u31 (Used Javara and reg cleaner to remove all old Java traces)
• Uninstalled and reinstalled bit JRE 7 (Used Javara and reg cleaner to remove all old Java traces)
• Used SFC /scannow in safe mode to verify Windows files
• Ran spyware and virus scan with no issues detected
• Added all java processes to windows firewall
I am out of solutions here. If anyone has had this problem with Java or knows what I need to do to fix the problem your advice would be greatly appreciated. I don’t think reinstalling windows is the solution because this is a fresh install.

Help with creating an animated java applet...
Hello, everyone! I'm working on a homework assignment for my Intro to Java class, and I'm having a problem I've never run into before. My assignment is to create a animated Java applet which displays an image of an alien spaceship which travels in diagonal lines across the applet area. My main problem is that when I try to compile my code, I get three "cannot find symbol" errors about my variable "alien." I can't figure out why declaring it as a class variable hasn't solved my problem. The errors pop up for the repaint() method, as well as the pane.add and the paintIcon. Here's my code:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.Timer;
class DrawAlien extends JPanel
public class Alien extends JApplet implements ActionListener
ImageIcon alien;
public void init()
Container pane = getContentPane();
alien = new ImageIcon(getClass().getResource("alien.gif"));
pane.setBackground(Color.black);
pane.add(alien);
Timer timer = new Timer(30, this);
timer.start();
public void actionPerformed(ActionEvent e)
alien.repaint();
}I've only posted the section which I think is relevant to my problem, but I can post the rest if anyone thinks it's necessary.
I'm aware that the code isn't ready yet in several other ways, but I don't think I can move on until I figure out what's up with the "alien" variable. I don't need anyone to write code for me or anything like that, I just lack perspective here. A couple hints in the right direction would be invaluable. Thanks!
Edited by: springer on Nov 25, 2007 10:46 PMYou can?t add ImageIcon into pane, you can do like below.
alien = new ImageIcon(getClass().getResource("alien.gif"));
pane.setBackground(Color.black);
JLabel label = new JLabel(alien);
pane.add(label); -
Forms Client Java Applet waiting several minutes
Hello,
We use Forms 10.1.2.0 and html/javascript/plsql applications.
All forms applications are working but
we have the problem that from time to time the client java applet must wait minutes until there is an answer from the forms-servlet (especially when there is high activity in the system).
More than one user is working in the form with high activity - the applet sends a request
over the network - after 4 minutes the result is shown and you can go on working
without problems.
So a lot of users think the application has crashed and terminate before.
The applet shows no error messages.
There is no sign that there is a lost connection between applet and servlet.
It is not reproducible. That means you can work 2 hours and everything is ok
or you work 5 minutes and you have to wait.
network problems?
firewall problems?
do requests of the forms servlet to the database have minor priority on the application server
than html/plsql requests?
any ideas?when the problem occurs (user has to wait 3-4 minutes) we found in the log
3 heartbeats from the forms client within 2 seconds ?
after 3-4 minutes the forms client is ok (user can go on working)
and the pings are every 2 minutes (like it is expected).
The application.log file may contain duplicate posts requests with
identical pragma header numbers, indicating that the client
is resending
requests due to network packet losses. Under normal circumstances,
only the last Post request, terminating a Forms session,
should contain
a duplicate pragma header number.
...a network problem ?
anyone else who had the same problem ? -
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.

Printing problem on java applet
Hi, I'm Korean and MacBook air user.
I'm very not good at English, please excuse me .
I use OS X 10.8.3 and jdk 7.
I make a simple java applet program includes printing functionary.
But, only browsers (Safari and FireFox) on Mac OS X not printing font correctly.
I use setFont() function and then drawString() function.
If you cannot understand my question, enter the link below. I think that question is same with my question.
http://stackoverflow.com/questions/15466060/java-app-on-mac-os-x-not-printing-fo nts-correctly
Thank you for reading my question.Points/questions.
It is a lot easier to debug these things if we can see the applet. Is it on the net? Can you give us the URL?
Have you considered launching this applet using web start? (If it turns out to be related to security, the web
start JNLP API has a neat way to sidestep that problem.)
Edit 1: Deleted the entire first two paragraphs when realised you said 'always prints'.

Java Applets not running in Any browser
Hi,
I have JRE / JSE (1.6.17) installed on a windows 7, 32 bit Intel Machine.
I am able to do all the programming and stuff (in Java), but when i try to open a web page with a Java Applet, it just does not show.
The page gives a message saying that an additional plugin is required.
I tried, Google Chrome, Firefox, Internet Explorer...all have the same problem.
The environment variables are correctly set.
This is something completely new for me, so would appreciate some helpActually i think its more related to JRE.
I was actually referring to general applet loading.
I cannot open any applet in any browser. -
Java applet will not install in browser
My VI will not install a JAva Applet. I jsut keeps saying "Installing Java Applet" and it never prompts for an install or anything. Any ideas? Is there something extra that I need to do that I am not realizing? I attached a screenshot of the window where is says installing.
Solved!
