Getting Applet to Work in an HTML Document

I have written an Applet which works perfectly in the Applet Viewer, but crashes when I attempt to put it on my web page. The crash gives no errors, no exceptions, no nothing. Just a grey square with the words "Applet Crashed". I tried it both with the files in a .jar,and with all the files uncompressed, and used the W3C's code validator at http://validator.w3.org/ to verify that my HTML is correct.
The HTML code using the .jar file is:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<a bunch of HTML code>
<object data="ComicTemplate.class" type="applet/java" archive="AICS.jar" WIDTH=620 HEIGHT=650>
If you can read this, your broswer doesn't support Java. Go to Sun's website to get the latest version of Java. You may also need to turn on Java in your browser's preferences.
</object>
<more HTML>
</html>
The code without the .jar is the same, except that the archive lists the 8 .class files and 18 images used individually.
Any advice?

I tried it both ways. It works using either method in the applet viewer, but niether works in the browser.
In the good news, however, I found a hidden Java console inmy browser, which did have some error messages. Cut-n-pasted:
-- Opera Java Console --

Getting applets to work in Firefox or IE7!!

Hi folks.
I've been reading Jason Hunters excellet book on Java Servlet Programming and become rather stuck on being able to get applets to work in a browser.
1) I managed to briefly get an Applet to work in IE7. Then things went astray (I say work, because applet initially displayed correctly graphically)
2) I introduced a bug and tried to redisplay. And haven't been able to recover.
3) When 2) occurred I swapped over to Firefox, since IE7 doesn't have a Java Console. (& theres no setting to enable it in security settings either)
4) Then Firefox prompted to download JRE... This was an odd one to me.... Since I already had a Java runtime...
I got this through downloading file java_app_platform_sdk-5_04-windows.exe
java -version yeilds:
Microsoft Windows XP [Version 5.1.2600]
(C) Copyright 1985-2001 Microsoft Corp.
C:\Documents and Settings\Jeremy>java -version
java version "1.6.0_04"
Java(TM) SE Runtime Environment (build 1.6.0_04-b12)
Java HotSpot(TM) Client VM (build 10.0-b19, mixed mode)
C:\Documents and Settings\Jeremy>
Browser Versions
IE : is at version 7.0.5730.13
Firefox started out at 2.0.0.12... Now Firefox didn't seem to detect the JRE
5) It said additional plugins are required to display the media on this page...
6) I clicked the button to "Install missing plugins"
It then presents Plugin Finder Service with "Available Plugin Downloads" of Java Runtime Environment with checkbox ticked.
7) I clicked "next", at which point it completes saying
No plugins were installed
Java Runtime Environment failed with "Manual Install" button...
Clicking said button gave me executeable xpiinstall.exe from http://sdlc-esd.sun.com
8) When I ran this it
a) proceeded to cause Firefox to crash and a report was sent to Mozilla...
b) created a restore point called "Installed Java (TM) 6 update 5..
9)So now I went back to IE 7 having given up on Firefox...
Now it complained about missing classes which I felt sure were in a jar I'd deployed in Tomcat...
10) I tried to validate my assumptions by looking inside the Jar with Winzip...
Then I got a pop up with "Java Virtual Machine Launcher" in its title saying..
"Failed to load Main-Class manifest attribute from cos.jar"
At this point I realised 8) was the culprit after posting here and looking at possible causes for said pop-up.
[http://www.artima.com/forums/flat.jsp?forum=1&thread=61427&start=75&msRange=15]
None of solutions posted there seemed to apply to me
11) So now I restored to a restore point prior to 8) and though my problems were over
12) I've since upgraded to Firefox 2.0.0.14. Firefox pushed update to me. Also tried manually uninstalling and downloading file. Still saying missing plugin!!!
13) I've tried changing my tags in my html from
APPLET to OBJECT for IE7 or EMBED for Firefox..
I've validated my APPLET with APPLETVIEWER following advice posted here:
[http://java.sun.com/docs/books/tutorial/deployment/applet/index.html]
No tell tale signs appear in Tomcat Console or logs..
*The only thing that seems weird is codebase tag*
14) Book I've been reading mentioned putting both html code and applet class in root folder of tomcat
I've hosted both files here:
C:\Apps\apache-tomcat-6.0.16\webapps\ROOT
15) When I test with appletviewer from this folder and codebase set to / appletviewer doesn't find class.
I think I need to set this so when web browser runs it finds class. Maybe this is the route of my problems.
What's haunting me here though is placeholder for applet graphic worked at one point!
I don't recall fussing with codebase attribute of applet tag, yet suddenly things stopped working.
16) When I tried to verify with appletviewer I had to remove codebase attribute completely to get things to work.
Here are three versions of html file. Firefox version doesn't seem to be recognized by Appletviewer
Applet tag version: (BTW have tried with CODEBASE=/ too. This was how it appeared in book, Remember I'm hosting in Tomcat 6.0.16)

I don't want to be staring at a placeholder in a Web Browser.
I want to GUI as it appears in AppletViewer and how it once had it working in IE7!
You wouldn' t think that was to much to ask for would you! Sorry for length of this post.
Any clues as to where to go next would be greatly appreciated as I'm pulling hairs out with frustration at the moment...
A few of footnotes:
1) I've relaxed my security zone settings for intranet, added localhost to local intranet sites..
2) I've tried deleting all temporay files in IE7 even to point of resetting to install setup thinking there may be some sort of caching issue with bad applet... No luck
3) I can still get Glassfish server to login to Admin Console.
So the integrity of my pc should me intact based on the shenanigans of point 11. Restoring to get rid of second JRE

I'm not sure what to tell you. I've never had any trouble installing the JRE and getting applets to work. Maybe it's an IE7 thing. Firefox is usually easier to configure.
Anyway, it sounds like something that you need to be sitting at your computer to fix, so I don't know how useful a forum will be. It might be best just to ask a coworker with a lot of arcane knowledge to take a look at it.1) Unfortunately I'm learning from home and don't have the luxury of asking a co-worker. Have fired off email to one of folks at Sun..
In my efforts to try and track down the problem yesterday, Google uncovered some interesting findings regarding Caching of Applets. Thought I'd share this:
2) [http://www.velocityreviews.com/forums/t603400-ltobjectgt-tag-and-applet-caching.html]
There is an interesting post some way down posted by james.a.cleland
Quote:
"My solution is to x-c in the Java console to clear
this cache. This works without unloading the JVM and while the applet
is running. It looks like the browser isn't caching any applets. At
least my browser cache doesn't contain any, although I do regularly
use half a dozen, so it must be the JRE. Anyway, clearing through the
console solves my problem".
I can't access Java Console in IE7 as you know...
3) There is always another way to skin a cat regarding clearing cache.
Found this here:
[http://www.aurigma.com/Support/DocViewer/28/UpdatingImageUploaderonClientSide.htm.aspx]
Search for Java section
Quote:
"Java applets are stored in the cache that is accessible through the Java control panel. Follow these steps to do it:
Open Java Plug-in Control Panel. Depending on the platform, it can be found in different locations:
Windows: Control Panel -> Java Plug-in
Click the Cache tab.
Click Clear to clear all cached applets."
*Problem is that there is no Java Plug-In within Control panel. Mentioned this with Coffee Cup reference above..*
4) Also saw this article on *"How to troubleshoot Java applet and component download problems"* at:
[http://support.microsoft.com/kb/241111]
Java console or output log section:
Javalog.txt in the windows\java or winnt\java directory
windows\java contains

No such file: classes & trustdb are empty folders.

Yep. That's my predicament.
BTW: Get this by doing test here:

6) Sun's Verify Installation fails on me too:
[http://www.java.com/en/download/installed.jsp]
7) I'm interested in knowing how IE7 caches the applets too. Does it store some sort of class-id in the registry? (I'm on XP SP2)
8) Is there an installation integrity verifier for Sun? Something that verifies the integrity against a baseline install and reports anomalies.Like I mentioned earlier I've got java_app_platform_sdk-5_04-windows.exe file installed. Not the latest incarnation, but the one immediately before. With SE 1.6.0_04-b12 built built into it

Getting applets to work in IE

How do I get applets to work with IE without downloading Sun java plugin?
I have the following html
<applet code=Foo.class width=100 height=100>
</applet>
This works great on Mozilla (both windoze and linux).
But IE complains that it cannot find the classfile Foo.class
If I install sun java plugin then it works fine on IE, but it doesnt work with the default microsoft jvm.
How do I get it to work in microsoft vm, as downloading sun plugins is a pain.
Thanks,

The applet has to use only classes and resources that exist in early version 1.1 Java (not sure of the exact version) and be compiled with that version compiler or use a compiler target option of 1.1. Because MS altered Java, there may still be incompatibilities with anyone else's Java.
Probably, IE complains about foo because it's using 1.2 or later features.

I upgraded to Mountain lion. I could not open any of my word documents so i downloaded Libre Office. It is downloaded but how do I get it to work with my old documents??

I don't know what file formats LibreOffice supports, but my guess is it can only handle the OpenXML format (new Office docs).
You could use this online converter: http://www.zamzar.com/convert/doc-to-docx/

Getting Applets to Work on the Web

Last semester, I took a Java programming class. While polishing up my resume recently, I decided that a couple of assignments I did for the class would look good in my porfolio, and attempted to upload them to my website.
Unfortunately, the class I took focused exclusively on getting applets to run on you local machine. Nothing I did for the class works in a web browser. This leads me to two questions:
1) IMO, Java that doesn't work in a web browser pretty much defeats the purpose of using Java. Since my local college's Comp Sci program is obviously failing in this regard, what are good resources to learn the Right Way to program in Java (ie, the way that works in web browsers)?
2) Are any of the things I did in class salvagable by any means short of starting over from scratch? Below is a cut-n-paste of a typical applet we wrote for the class, using the teacher's reccomended methods. If someone could point me in the right direction for getting this to work in a browser, I'd be very grateful.:

1) Applets that run in web browsers used to be "hip" in at one point in the dark 1990's. That time is forever gone and good riddance. Today big enterprise applications and sophisticated special purpose desktop applications are the Right Way™ to go with Java.
If you want action in your browser, look into Macromedia's Flash technology.
If you want to deploy your application easily in an applet-like fashion (one click from a browser), look into Java Webstart.
Demos: http://java.sun.com/products/javawebstart/demos.html
Documentation: http://java.sun.com/products/javawebstart/developers.html
2) It's a trivial task to write a launcher applet for any given application so that the applet starts the application in a new window. The security restrictions imposed on applets ("sandbox") might make it impossible to use the application; for instance you cannot write or read files on the local hard drive or make network connections to other servers than where the applet was loaded from. You cannot call System.exit to quit the virtual machine.
At its simplest the lancher applet code would look ilke:public class Launcher extends java.applet.Applet {
public void start() {
YourApplicatioMainClass.main(null);
}and in the html you would write:<applet code="Launcher" height="1" width="1">
</applet>See the "Writing applets" tutorial for further information http://java.sun.com/docs/books/tutorial/applet/index.html

I'm unable to get Dictation to work in a Word document.

I havne't used Dictation before--am trying to get it going in an existing Word document. I have the insertion point at the right place in the document, press the fn key twice, and begin dictating. Nothing registers in the document. What am I missing/doing wrong? Thanks.

Thanks very much, but I've managed to do it by copy-and-pasting to an email, then to word.
Thanks for your help!

Can't get Export to work

I'm relatively new to Fireworks. I created a small image map, but when I try to export the image and html to Dreamweaver, I get a message a message saying "Could not complete your request - The file was not found." I've tried Export, Export Wizard, rebooting, and a bunch of other stuff - but still can't get it to work. I'm using the Trial version (but it's the same as the regular version, right?) on a Mac running SnowLeopard.
Other than this, and an issue with the Text function that I posted about in a different thread, I like Fireworks a lot and was planning to buy it - so I hope there's a way to get Export to work with images/html so it won't be a showstopper. I'm assuming I must be doing something wrong.
Thanks.

Linda, thanks for responding to my question.
Unfortunately, I'm unable to upload the file to you. Everything I try gives the "file not found" message (but the file is right there on my screen, in front of me as I'm getting this message), so I don't know how to get it to you. The only way that I've found to get the file "out" of Fireworks is to save it as a .jpg file (which of course eliminates the "hotspots" and associated html), and then open it in Mac's Preview utility and also in Dreamweaver. I could send you the .jpg file if you'd like, but since it no longer contains the hotspots and there's no html, I'm not sure that's too useful.
I tried adding the clickable hotspots back in with Dreamweaver, and that worked and also produced usable html.
I noted in a separate forum message that the Text function has also stopped working for me, although it was fine initially. However, I can no longer add text, and when I try to edit existing text, the existing text disappears from my image.
Has my copy of Fireworks somehow become corrupted? Should I reinstall? Other than these issues, I like the product a lot and would like to be able to use it.
Thanks!

I can't get my applet to work in HTML

I have written an applet that works perfectly OK when I run it at the command line. However, if I try running it from an HTML file it just doesn't work. I get an 'Applet ImageApplet notinited' message in the bar at the bottom of the page. I assume this means that the applets init() method hasn't been called. I find this a bit strange,as I am calling the init() method from my main method.
The code for the Applet is pasted below. I've also pasted the code from another class (ImageCanvas). The ImageCanvas class is used by my Applet. Please let me know, if you know how to fix this problem. Thanks in advance.

Need help getting my applets to work on web pages!

I've been trying to get it to work for a while now, and I no idea why it won't work! I've tried all kinds of things to get it to work, but it still won't work. All I want to do is make a simple applet, don't care what it does, and put it on a web page.
Here is my HTML code:
<applet code=?Slime2P.class? height=?300? width=?400? codebase=?http://www.spinarcade.com/tests?>
</APPLET>
Here is a link to what happens:
[http://www.spinarcade.com/tests/duk.html|http://www.spinarcade.com/tests/duk.html]
Here is the errors:
load: class ?Slime2P.class? not found.
java.lang.ClassNotFoundException: ?Slime2P.class?
     at sun.applet.AppletClassLoader.findClass(Unknown Source)
     at java.lang.ClassLoader.loadClass(Unknown Source)

     at sun.applet.AppletPanel.runLoader(Unknown Source)
     at sun.applet.AppletPanel.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
It works fine when I run the applet in eclipse, and I've tried many different applets. I tried using a cool program I wanted to put online first, then I made a simple program to try, and then I even downloaded the file from a tutorial and didn't edit it at all... nothing works!
Here's code from one of the applets (Simple applet with green lines):
import java.applet.*;
import java.awt.*;
public class Duck extends Applet {
int width, height;
public void init() {
width = getSize().width;
height = getSize().height;
setBackground( Color.black );
public void paint( Graphics g ) {
g.setColor( Color.green );
for ( int i = 0; i < 10; ++i ) {
g.drawLine( width, height, i * width / 10, 0 );
I have all the .class file and the html page in the same place (http://www.spinarcade.com/tests).
Thank you for your help! It is most likely something simple...

Look at the double quotes used in the applet tag now!!!

Internal Links in HTML Document Not Working Correctly in PDF

I have an HTML document that contains internal links (basically a Table of Contents). When the document is displayed in a browser, the internal links work correctly. However, when I use Acrobat 8 Professional to create a PDF version from the HTML source, the links don't go to the correct place when clicked. It almost appears that they are off by one, e.g., link 7 goes to anchor 8. I can send the source document for you to look at if you email me at eharris -at- synnovation.com. I am not expert in HTML and perhaps the links/anchors are not done correctly when I create the HTML document. Does anyone have any ideas on this?

This one has the same problem. For instance, "Anchor1" as <a name="Anchor1"> appears 13 times. I am sure that your problem is that Acrobat is going to the last occurance that is just before the first one. As I scan through the file I find similar results for all of the anchors. When I used Tidy, it reduces about 1350 errors to about 474, but that is still not too good. The validator is flagging a lot of identical IDs as well as unrecognized attributes (like ONSELECTSTART). The attributes correctly accepted by body are
Attribute Specifications
* BACKGROUND=URI (background image for document)
* BGCOLOR=Color (background color for document)
* TEXT=Color (text color for document)
* LINK=Color (link color for document)
* VLINK=Color (visited link color for document)
* ALINK=Color (active link color for document)
* ONLOAD=Script (document has been loaded)
* ONUNLOAD=Script (document has been exited)
as listed on htmlhelp.com for HTML 4. There may be some new ones in HTML 5, but I did not check.
I am not looking at all of your HTML in detail, but there appears to be a lot of unneeded things based on the error messages from the validator. Many browsers will let you display the stuff (even Acrobat), but there may be errors that crop in when you do not expect it or on some other browsers that the one you check. Thus again, you should use a validator. If you are only off a few tags that might be fine, but when it is in the 1000s, there is an issue. It would also be good to break your page up into parts. It is good practice on web pages for each page to be not much more than one screen. That is often exceeded, but 59 screens of info (on my screen) is a bit much. The TOC is definitely needed in that case, but just was well go to a sub page just as well and make the info easier to track. A PDF (as you are trying to get) could be made of the entire system for those that want it all in one bit. Bill

How do I get an applet to work on a web page?

I made an applet, but on my computer it only works when I have the JRE installed, and not when it isn't installed. Currently, it doesn't work on the website I put it on unless the computer accessing the website has the JRE installed. Is there any way to get it to work anyways? I know that at least some applets work when I don't have the JRE installed. Why won't mine?

to run an applet a JRE must be installed. both netscape and IE have default 1.1 compliant jres built in, but you almost certainly don't want to use those, you probably want to use the plugin. to get your applet to use the plugin whether on not it is installed you use a particular html tag. see http://java.sun.com/j2se/1.4.2/docs/guide/plugin/ for details, but briefly you would use something like:
<html>
<head>
<title>IWS Chat</title>
</head>
<body bgcolor="#FFFFFF" text="#000000">
<OBJECT
classid = "clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
codebase = "http://java.sun.com/products/plugin/autodl/jinstall-1_4-windows-i586.cab#Version=1,4,0,0"
WIDTH = 100 HEIGHT = 100 >
<PARAM NAME = CODE VALUE = "infoworkspace.applet.AnApplet.class" >
<PARAM NAME = ARCHIVE VALUE = "applet.jar" >
<PARAM NAME = "type" VALUE = "application/x-java-applet;version=1.4">
<PARAM NAME = "scriptable" VALUE = "false">
<COMMENT>
<EMBED
type = "application/x-java-applet;version=1.4"
CODE = "infoworkspace.applet.AnApplet.class"
ARCHIVE = "applet.jar"
WIDTH = 100
HEIGHT = 100
scriptable = false
pluginspage = "http://java.sun.com/products/plugin/index.html#download">
<NOEMBED>
</NOEMBED>
</EMBED>
</COMMENT>
</OBJECT>
</body>
</html>
this will install the plugin for you and start the applet.
hope this helps, Mitchell

How to get Safari to open an HTML document created in AIR on iOS

We have an iOS app that creates a 3-page HTML document on the user's device and then prints it. We were using Darkredz ANE to do this, but the ANE is broken in iOS 8 and the Darkredz website is abandoned.
As a workaround, we want to use Safari to launch the HTML document, then print from Safari. But Safari won't open a local document that belongs to another app, probably because of the security sandbox. We don't have a network connection, so we can't save the file remotely. Is there a way to get Safari to open a local document?
If not, does anyone know of a FileManager app that can open files that are located in the "documents" folder of other apps on the device? I've tried several of them, but so far, they only load files from iCloud, Box, etc.
Thanks for any tips.

Sorry I didnt think about it needing to print as 3 separate pages at specific points. If you can't get the HTML printing to work then you could keep could this thought in mind. If the height of the, I presume, HTMLLoader object is the right value, you can draw the white-space of the page into the BitmapData and then it might still print at the right location. If it doesn't work immediately and you felt like putting in a little more effort, you might be able to tweak the height of the HTMLLoader objects so that each one represents a single page. Granted this approach would likely only work for one paper size format, such as 8.5x11. Sorry I don't have any easier ideas that work with what you already have done so far

A helloworld java applet that will work on an html file

I have spent a lot of time trying to get a java applet to work on a web page. Of course, I can download zip packages and they will work. But I can?t seem to find a formula for creating something simple that will work.
All the examples that I have found will either work on Windows when running it on the command line, or work in Netbeans, but none of them will work when I put time into an html file on a linux web server.
Can someone post, maybe the simplest code that will output ?Hello world? on a Linux Apache Web server.
I have the gist for creating and programming java? as least a basic start. But I?m anxious to see an example that I can compile that will actually display on an html file and not just my Windows programming environment.
Thanks in advance for any feedback on this.

Is that a question? Please make sure to add a question mark.
// <applet code='HelloWorldApplet' width='400' height='300'></applet>
import javax.swing.*;
public class HelloWorldApplet extends JApplet {
public void init() {
add(new JLabel("Hello World!"));
validate();
I have the gist for creating and programming java as least a basic start. ... Applets are not for newbies. Leave them alone for at least another 6 months.Thanks, Andrew. The lines of text you provided were very enlightening. I was able to do a lot of dissecting and experimenting and have the full gist of my question answered. I don?t have any problems outputting either text on the console or text on browsers.

Problem Getting An Applet To Work

Hi,
I hope there is someone out there that can help me with this problem.
I'm trying to get an applet to work inside of IE6 and I'm getting the following error message via Java Console,
Error loading class: demo
java.lang.ClassFormatError
java.lang.ClassNotFoundException: demo
     at com/ms/vm/loader/URLClassLoader.loadClass
     at com/ms/vm/loader/URLClassLoader.loadClass
     at com/ms/applet/AppletPanel.processSentEvent
     at com/ms/applet/AppletPanel.processSentEvent
     at com/ms/applet/AppletPanel.run
     at java/lang/Thread.run
The java code is as follows,
import java.applet.*;
import java.awt.*;
public class demo extends Applet {
public void init() {
public void paint(Graphics g) {
g.drawString("Hello World", 50, 50);
And the html (demo.htm) is
<html>
<head>
</head>
<body bgcolor="#00DCFF">
<applet name="demo" code="demo.class" width="300" height="200">
</applet>
</body>
</html>
Both demo.htm and demo.class are both in the same directory. I used the Sun Java SDK version 1.4.1 to produce the class.
I can get it to work if I enable
Java (Sun)
Use Java 2 v1.4.1 for applet
within the Advanced options of IE6, but I don't want to have to force the user to have to either load the the SDK or the plug-in (by using OBJECT/EMBED) due to their size.
thanks in advance,
Wayne
