Cannot load applet

Hello to all,
I am developing an application, using JSF, in which I have used applet to upload the directory. But I am not able to load that applet in the browser.
My code is
<jsp:plugin codebase="." code="DirUpload"      height="100" jreversion="1.6" type="applet" width="250">
         <jsp:fallback>Your browser can't display this applet.</jsp:fallback>
</jsp:plugin>It gives me error on the Browser's Java Console
load: class DirUpload not found.

I have also tried to change the codebase to my lib folder
Thanks in advance.

..My applet is responding as it should.What exact applet element were you using? What is the path to the applet HTML?
I am using eclipse for my application in which the lib folder is under the "WebContent/WEB-INF" I suspected as much, by the combination of 'JSF and lib'.
Resources under WEB-INF are only for the servers use. If you try a direct fetch in the browser (using the http://.. style address) the server will provide a message to the effect that the resource is not available. Long story short, the archive used for the applet, as well as the applet web page, must both be in locations where the server will provide them to a browser (by http://.. URL in the browser).
In future, you might do a test in your browser, for each resource mentioned.

IE 6.0 cannot load Applet file

I've found big number of topics about same problem, but I still cannot fix it. I have java 131_2 with SUN plugin. When I try to run very simple applet, IE stopped in "loading Java Applet...".And I've got the following exceptions:
java.lang.NoClassDefFoundError: sun/misc/ClassFileTransformer
at sun.plugin.security.JDK11ClassFileTransformer.init(Unknown Source)

I'll really appretiate any help.

Ahh, I was stuck with this problem
The solution is within one of the options you can select when compiling
Java 1.4 gives the user the option to compile into 1.3, 1.2 and 1.1
try using the following command
c:\>javac -target 1.2 SourceCode.java
Hope this helps

Bridge2Java wrapper IE Browser cannot load applets

I download the bridge2java library and modify one of the samples (QuickIE.java) to visit a url that contains a simple applet (e.g. http://java.sun.com/docs/books/tutorial/uiswing/components/applet.html)
Once the page is loaded, a alert box popped out and said 'Java(TM) Plug-in Fatal Error, Attachment to a running virtual machine failed'. The page is fine when i view it in IE alone.
My machine is WINXP, heard that no such problem in WIN2K. It has 2 jdk, one j2sdk1.4.0_01 and a j2sdk1.4 jre bundled with JBuilder. (Also, j2sdk1.4.2 just uninstalled when i tried to fix the problem). I have set JAVA_HOME to C:\j2sdk1.4.1_01 and add 'C:\j2sdk1.4.1_01\bin' at the beginning of the path.
Anybody knows why that happen? Is it due to my configuration or just a bug in bridge2java? Thanks.

Cannot load applet; coffee cup and exclamation point shown, or black box

I am having trouble loading several Java applets under Safari for Windows. These will load with a coffee cup image with an exclamation point over top, or sometimes will simply show a black retangle. How can I go about troubleshooting this? I see no Java Console anywhere in Safari and no other trace of what's going on. How can I debug this?

Are you using the webkit version of Safari? I think it has more diagnostic information than the public releases.

Cannot load an applet in a local file

With
Fedora Core 3
JDK 1.5.0_05
Firefox 1.0.7 or Appletviewer
I can load most applets loaded fron web sites. But I cannot load a simple file:
<html>
<head><title>diagnostics</title></head>
<body>
<h1>example applet1</h1>
<applet codebase="." code=Applet1" width=120 height=120>
</applet>
</body>
</html>
with a simple hello world applet like:
import java.awt.*;
import java.applet.*;
public class Applet1 extends Applet {
public void paint(Graphics g) {
g.drawString("Hello World", 10, 10);
Loading the page it reports a General exception:
java.lang.ClassNotFoundException: Applet1
Both files are in the same directory.
It happens both with firefox and appletviewer.
I would appreciate any help or feedback of similar behaviour.
Manchu.

I just let your code run in JCreator and I found 1 error in yout HTML code:
<applet codebase="." code="Applet1" width=120 height=120>(that is how the line should look like, corrected)

Appletviewer cannot load Swing Applet

Hi. there
I'm facing the problem that appleviewer cannot load
my swing applet.
Acctually, a few days ago, before I implemented Button Event Handling, appleviewer work properly.
But now It's not working.
java -verbose appletviewer jadmin.html
-> Exception in thread "main" java.lang.NoClassDefFoundError: appletviewer
I already reinstall JDK1.3 because I chaged java.policy file.
and then this is not a source-level problem, I put into source System.out.pritln(), but not printed.
This is my classpath and path.
[classpath]
.;C:\jdk1.3\jre\lib\rt.jar;C:\jdk1.3\lib\tools.jar;C:\jakarta-tomcat-3.2\lib\servlet.jar;C:\jkjdbc\jkjdbc.jar
[path]
.;C:\jdk1.3\bin;C:\jdk1.3\Jre\bin;C:\Program Files\Microsoft SDK for Java 4.0\Bin
Please Let me Know about it.
Thank you for reading.
p.s In Current source, several inner classes(event handling class), but appletviewer work properly with inner class prev. source that I mentioned.

Hi,
You don't have to call java to run the appletviewer. You'll onlyhave to run:
appletviewer jadmin.html
to make it work.

Kurt.

Unable to load applet on one machine, but runs fine on others

Hi there
I have created and deployed, successfully, a JavaFX applet which I tested on my development machine and a separate machine and all is fine. The Applet with its associated HTML, JNLP and JAR file reside on a webserver, and my testing was still successful (and another colleague tried also).
I proudly announced the location to others within the organisation (sorry I am not able to share the URL) and one person reported that all was fine, they loaded and used the application, the other reported the following error message:
Ignored exception: java.lang.NullPointerException
exception: JNLP file error: xxx_browser.jnlp. Please make sure the file exists and check if "codebase" and "href" in the JNLP file are correct..
java.io.FileNotFoundException: JNLP file error: xxx_browser.jnlp. Please make sure the file exists and check if the "codebase" an "href" in the JNLP file are correct.

     at java.lang.Thread.run(Unknown source)
Exception: java.io.FileNotFoundException: JNLP file error: xxx_browser.jnlp
This person, who is in a remote site (so not yet been able to visit the machine) is using Windows XP, IE 6.0. I have a machine which also runs this setup and can load the application.
I am really unsure what could be the problem. I have even asked the user to load the Winter Olympics JavaFX visualisation to see if that works (it does).
Can anyone give me any advise? I am guessing it is a problem local to that machine, rather than the JavaFX application?

Hi there
An update on this situation. I managed to visit said machine on Friday and found the following:
1 - The error in the Java console is:
java.io.FileNotFoundException: JNLP file error: XXX_browser.jnlp. Please make sure the file exists and check if "codebase" and "href" in the JNLP file are correct.
2 - I was able to browse, and resolve, the XXX_browser.jnlp file
3 - The client was able to load other JavaFX applets from the same server/website but they were not behind any password protection.
4 - The client is able to use the JavaFX application via the XXX.jnlp file (i.e. web start)
Whilst on site I noticed that IE was reporting "Could not find privacy policy for http://dl.javafx.com/ping.js". I added this site to the browsers accepted list, and marked this as Always allow this site to use cookies but to no avail.
Remember, this site does work for another user.
My thinking now is, when executing the URL to load the HTML you have to enter a password, (which we did), this loads the HTML which then tries to load the JAR file (in the same location) but for some reason it in turn cannot load it XX_browser.jnlp file and it is does not challenge for a username and password again (like it does when you run it as a web start).
Any thoughts?

Failed to load applet in HTML page

Hi,
I cannot load my applet under IE9+, Chrome (v28). The applet is signed because it access to file resources.
Applet deployment, Javascript code:
<script type="text/javascript" src="http://www.java.com/js/deployJava.js"></script>

var attributes = {'/files/ldep.jnlp'} ;
} else {

var attributes = { id:'ifsAuth', code:'org.ldep.AdminLogin', archive:'ldep.jar', width:1, height:1} ;

Is there something wrong in this code?
Thanks.

Applets run client side - which means the relevant class files need to be downloaded to the client.
Anything under the WEB-INF directory is not directly accessible by the client. Nothing under WEB-INF can be downloaded.
ergo, specifying the WEB-INF directory as part of your applet codebase is a bad idea.
I would suggest try copying the applet classes from under WEB-INF to some other place in your application.
Also, you should probably specify the full class name of your Applet in the plugin tag.
<%@ page import="com.util.MyApplet" %>
<jsp:plugin type="applet" code="com.util.MyApplet" codebase="/classes" width="250" height="100" jreversion="1.6">
     <jsp:fallback>
          <B>Unable to start plugin!</B>
     </jsp:fallback>
</jsp:plugin>cheers,

NoClassDefFoundError when loading Applets from IIS5.0

Hi
I am having trouble loading applets from IIS 5.0. Here is my html code
<applet code="Appli/Loader.class" width="100%" height="100%">
</applet>
All my clases and packages reside in the same directory from where this html is loaded.
The trouble is that it behaves erratically. At times the Applet works fine and at times, the browser cannot locate some class.
The funny part is this behaviour is not consistent. Some times the browser is able to load all the classes and the applet function very well.
Any suggestion/advice/tip will be great help
Thanks

Add the codebase parameter and see if it works.
<applet code="Appli/Loader.class" codebase="DIRECTORY_WHERE_YOUR_CODE_RESIDES" width="100%" height="100%">
</applet>

Using Firefox to access facebook chat Button or online friiend chat button generates a Black screen with CANNOT LOAD IMAGES and no chat window opens.

This does not happen in other browsers and it happens on a variety of computers I have access to and would seem to be a common problem but I can find no identical cases in my searches of
Firefox , Facebook or windows help or Google search. My home machine is only a P2 with WINXPCORP but works fine and I have done all updates but still have this continuing problem every time I try to use Firefox
to access Facebook chat but it does not happen with IE or chrome
The response to clicking on chat button or friend chat is a black screen with small center square box with blue title bar that says
'' VIEW IMAGE FULL SCREEN - (42) FACEBOOK X""
center of box is ""! "" mark in yellow triangle and wording
"" CANNOT LOAD IMAGES ''' OK
clicking on OK returns to facebook page but no chat opens.
Some times |VERY RARLEY if as the page loades you click on
chat button with 1/2 second of it appearing chat will open.

Error message: Cannot load the rpt file

Can anyone please help.
I created a Crystal Report which I deployed into Business One. Tested this report on about 13 machines running Business One and all running well except one machine where it comes up with the following error messages:
1: Cannot load the rpt file
2: Object reference not set to an instance of an object
3: Invalid report file path
I have tried logging into Business One on that machine as a different user and encountered the same issue. Then logged onto another machine as the user who uses the machine with the error message and her profile works well on another machine.
This is leaving me with concluding this problem could be down to the machine but cannot figure out how to fix it.
Does anyone have any ideas to solving this?
Thanks
Tony

Hi Tony,
On the troubled computer, check in Control Panel whether Crystal Report Runtime is installed. If not, un-install client app and re-install from B1_Shr client's folder. The first thing that it will do is to instal Crystal Report Runtime.
Source: when I did an upgrade on a client recently this happened. After troubleshooting everything I found that this issue is a hit-and-miss as some PCs had it some don't. I started comparing between working and non-working PC and found this is the only difference I could found.

The pass 4 days now my iTunes Store is not responding, when I reload it all that comes up is a blank white page that says iTunes Store. Help please!!!! Cannot load my gift card to buy music and such!!!

I tookyour suggestion and SUCCESS! I can now access the Itunes Store. A simple fix, and thanks so much!!.
Below is the advice you forwarded:
I found a solution to my problem.
> start menu
> accessories,
> right click on the command prompt icon and choose "run as administrator".
Once it opens, type in the following command...
netsh winsock reset
hit enter
You should get a message that the winsock reset successful and you will need to reboot your computer.
Reboot and when I reloaded itunes the store loaded fine.
Thanks again, -Dean Stoneburner

Internal error, cannot load engine Number 2 due to error 5

I have had a StartStop transcription program for several years. I bought my Dell computer with Windows 8 (now 8.1) in late 2014. I had no problems running the StartStop program until it got a tune-up by my regular tech. Since then, when I click to
open it, I get the message: "##### Internal error, cannot load engine Number 2 due to error 5." My tech couldn't figure it out and another tech couldn't fix it either after looking at it for hours. StartStop could not figure it out either.
Since then, I bought a Digitope digitalizer, which converts cassette tapes to CD's. When I try to open that program the exact same error message comes up!
So I am thinking there is something awry with certain audio programs. I am able to run another transcription program, Express Scribe.
Any thoughts!
The 2nd tech suggested rebooting the entire computer and reinstalling all programs, but I'm not sure I can find all my original programs.
Thanks!

Hello Silent Fisher,
What StartStop transcription program do you mean?
Please share me a screenshot.
If it is a third-party software, it is recommended to contact the support of the software.
If the issue occurs after your change, please use the system restore to restore your computer’s system files to an earlier point in time.

I rented a film on my iPad but when I try and watch it I get a message 'cannot load video' as soon as I get to around 15 minutes. The film is fully downloaded and paid for.

I Rented the film inhale on my iPad a few nights ago, this is not the first time I've rented from I turnes, I've don't it many times before and never had any problems. This time I cannot get the film to load. Every time I try to play the video it comes up with a message saying 'cannot load video' as soon as I reach around 15 minutes of the movi. and then shuts the video down. I'm annoyed because having got 15 minutes in my film will now expire in 48 hours even though I can't actually watch it. I'd like to see it tonight if anybody can help please, thanks.

Having the same problem. Watched 25 minutes of a rental and it stopped with the message"unable to load video"
