Applet Notinited.
Hello every one...
I face problem in loading my applet in IE 6.0.
The error message "applet <appletname> notinited" displays in the status bar.
The applet contains a JList , a JTextAField and a JButton.
It works well under AppletViewer.
weird?!
could anyone tell me how solve this problem?
Thank you very much !
Hi, I am also having the same problem...
we have a intranet site running, and several client machines connecting to the intranet server. all machines except one works perfectly.
on the one machine that it does not work on, it has the same error message mentioned above. so if all except one client machine works, surely the problem is not the codebase??
thank you in advance

I run the program using Eclipse; run as> Java applet
and in runs perfectly well. I then tried running it using internet explorer and firefox, but only a gray box appeared and the browser says "applet notinited" and "Loading Java Applet Failed.."
what did i do wrong? any help is really appreciated.. thanksthank God i already found the cause of the problem..
it's because the application has an ImageIcon which links to a local jpeg file, so perhaps security restriction on the browser doesn't allow my applet to access local file, that's why it fails to load.
either using signed applet (not tested) or removing the picture solved my problem.
thanks anyway :) -
I am receiving an error when my applet is loading
Java applet notinited
Using comments i have traced the error to:
Graphics tempGraph;
Image[] grid = new grid[someNumber];
for(int d = 0; d<someNumber; d++)
grid[d] = createImage(200,100);
//the following line is where the problem is...
tempGraph = grid[d].getGraphics();
}Any ideas?This is just a guess, because I can't see all your code...
But did you override the method init() in your applet? -
Can someone pls tell me what data applet notinited means?!!
Hi,
I installed the plug-in...I have Java 2 Runtime environment and plug in 1.3.1_01
the applet appears in IE, but netscape said the plug in has to be installed again. I installed the same thing again, and I got the message "data applet notinited"...
The applet however, still works fine with IE.
Please help!!
thank you,
SangeethaWell ando :)
Yeah, I agree...quite troublesome. Even now, the applet works fine when I access it using the server running on a different machine. But then, when I make a copy of those files on my machine, and have the webserver running on my own machine, and access it, it apears on IE, but doesn't appear on netscape.
The problem is, I have to develop netscape compatible code!!!
and btw, I am Ms. Sangeetha :)
thanks again!

Hi
I am a new in applet. i run htm on local iis. a small code with applet notinited error. It is in fact a with-parameter-version of http://javaboutique.internet.com/Blink/. I can run the sample applet perfectly
Applet code:
import java.awt.*;
import java.applet.*;
public class MyBlink extends Applet
String newlbl;
public void init()
newlbl = getParameter("lbl");
public void paint(Graphics g)
g.drawString(newlbl, 25, 25);
The code in htm calling applet:
<script type="text/javascript">
document.write("<applet code='MyBlink.class' width='300' height='300'><param name='lbl' value='hellloworld!'></applet>")
</script>
Any advise is appreciated.
shxj99harmmeijer
Thanks for your reply.
The reason is my forgetting to move XX.class to the running directory.
One more question here.
Before moving mouse in the applet area, the third and forth codes using double buffer in the following page initate with blank background. Please tell me why and how to handle it.

Hello,
I manage a few macs, and we use to scan using a printer/scanner on the network with a browser. From some computers (NOT ALL) the users receive an error "applet com.efi.appls.webtools.WebToolsApplet notinited". Is the same with Safari or Firefox. Anyone has any idea? (obviously all the macs are exactly the same, with mac os X 10.4.8, all upgrades done, Safari and Firefox last version).
Thank youok, the preferences are as shown in your picture on both computers. I have also deleted the files "in special folder" and the only thing changed is that the error received now is applet notloaded instead of notinited.
Obviously the users can use another mac, so is not a big problem, but I can't really understand why 2 macs on 11 behave like this...
Thank you for your help. If I will find a solution, I will post it. -
Applet Notinited - Loading Java Applet Failed
I tried looking for my particular failure on the forums and googling it, but no one else seems to have my particular affliction.
Obviously, when I try to load up my applets I created, even something as simple as a text readout, it gives me the notinited bit in the status bar.
Doesn't work in FireFox, IE, Opera and I'm runing 1.5
Doesn't work on my fiance's computer and she's running 1.4.2
I run the java console, and it lists the class not found exception. and also
an IOException error: open HTTP connection failed
I run the appletviewer and it lists java.lang.RuntimeException: java.security.AccessControlException: access denied (java.net.SocketPermission wolkefamily:80 connect,resolve)
the wolkefamily bit is my domain name.
i checked, and checked, and rechecked for binary transfers set, correct html, correct java syntax. i think it's all on my server end, but i don't have direct access to teh servers itself.
any ideas? and thank you.Obviously, when I try to load up my applets I
created, even something as simple as a text readout,
it gives me the notinited bit in the status bar.

How are you "loading up" your applets?
Are you calling applet viewer/ running from browser and how? -
Applet works in appletviewer but not in IE - Applet notinited
Hi, i have written a simple applet which uses swing components, ie swing labels and buttons. The buttons and labels also have icons with the text. The icons are in a folder called "icons" inside the same folder that the class is in. Everything works fine in the appletviewer, the icons are all displayed correctly, however when i try to open it through Internet Explorer i get this error in the java console window:
Java(TM) Plug-in: Version 1.4.0

Can anyone help me with this problem? I desperately need this applet working in the browser and not just the appletviewer.
Many thanks in advance,
AdrianHi, i don't think it is a problem with the security settings, the problem definately lies in these lines
inside the init method:
Icon worldIcon = new ImageIcon(getDocumentBase(),"icons/world.jpg");
JLabel myIconLbl = new JLabel("My Icon and Label", worldIcon, SwingConstants.CENTER);
add(myIconLbl);
If i take the ' getDocumentBase() ' part out of the first line, the applet compiles and the worldIcon is correctly displayed in the appletviewer but not in Internet Explorer (the problem i orriginally sited).
However by leaving the getDocumentBase() line in the code, the applet correctly compiles but does not show the icons at all in either appletviewer or IE!!
Any suggestions?

also, i would not declare index and j until i needed them in the loops. this could cause some slips where you don't expect it. but i'm not fixing that for you.

Problems with Applets notinited with SSL
This is a repost from the java programming area:
http://forum.java.sun.com/thread.jspa?threadID=5153036
I have an applet that will not init in the secure area, but works perfectly fine in the public area.
I'm pretty close to the end of my rope on this one, so if there is anyone that can help me on this I will be extremely grateful.which error does IE tell you?
-
I support some users that go onto a secure website and use certificates. They used the java 1.4.1 plugin and all is fine. Now they have a new machine, and the new Java plugin 1.4.2 throws up an error when you hit a button to select the certificate, runtime error line 53 bla bla bla, and at the bottom of the screen it says applet notinited. I don't know how to fix this error. I uninstalled the 1.4.2_07 and used the 1.4.1 and it still doesn't work, am confused, have 10 working machines and this one is causing a problem. I no nothing of Java apart from installing it.
Sorry I don't know much about Java, how would I go about doing that? The error I get is line 54 char 9 error Object doesn't support this property or method. Here is the page source don't if this helps or not?

Applet won't load, packet missing data?
I know this basic question gets asked a lot, but I have debug info!
Here's the setup:
- Simple HelloWorld applet on a Slax Linux system, Apache2 server
- Clients are win 2000 and win 98 machines, IE and Firefox
html code:
<html>
<body>
<center>
<h1> Applet Test 6 </h1>
<applet code="helloapp" width="320" height="320" codebase="."></applet>
</center>
</body>
</html>applet code:
import javax.swing.JApplet;
import java.awt.Graphics;
public class helloapp extends JAppplet
public void paint(Graphics g)
g.drawRect(0,0,getSize().width-1,getSize().height-1);
g.drawString("helllo",5,15);
}What happens:
- applet runs fine in appletviewer
- type in <ipadr>/Hello.html on win PC
- the html loads, waits for between a few seconds to tens of seconds
- get applet notinited error
- on the win 98 machine the Java applet loading logo shows up briefly
- end up with the dreaded box with 'X'
- I did get it to work the other day after adding 'classpath="."' to the <applet> code, but that doesn't seem to help now. class and html are in the same directory.
- I have tried class="helloapp" and class="helloapp.class" in the <applet> code
Debug info:
- Java console says helloapp.class not found, and sometimes an EOF error
- packet sniffer shows (leaving out, ACKs, SYNs) (pc -> linux) :
-> request fro html
<- html code delivered
-> request for helloapp.class
<- deliver helloapp.class (SEE NOTE BELOW)
-> rerequest helloapp.class
<- redeliver (SEE NOTE)
-> finally sends RST flag
NOTE: these packet looks right except I don't see any data. It's 372 bytes long but it says it has a content of 532 bytes of data:

Questions:
- Am I right in not seeing data (the applet code) in the packet above - it should be there right?
- Could something in the Apache configuration prevent it from sending the applet data? I did set the permissions in the configuration file.
- Any other way to debug this?
- The fact it worked the other day and not now is perplexing. The linux I am running is a live version, so I have to reconfigure each time I start it. I have to think the problem is there as that is the only thing that has changed since the other day....Here's a partial answer. I found that if the data load in the packet was over 256 bytes, it would fail. I a able to create an empty applet of 192 bytes that would load. I figured out the 256 byte number using wget and some text files. So I guess it's not an applet problem, but maybe an Apache problem.

Hi,
I'm new to Java so hopefully you'll be able to clear something up for me. I have had a look round, but am struggling due to my lack of Java knowledge.
I have an application which passes an applet to IE. The connection is over https. With anything else other than 1.4 JVM installed, its fine, but with 1.4 I see "applet notinited" followed by "load failed".
Both the server and client use certificates and I've been told this won't work with client certs - not sure why, so the first question...is there a bug in 1.4 related to the use of client certs?
Here is a cut of the console log....
lots of...loaded certificates messages (no errors/warnings)
then....
a connecting to the site message (no errors/warnings)
then...

Now, without client certificates I also have issues....so, the second question - is there something here which is not client certificate related, and although I would never speculate....https related for example?
Thank you very much for any helpHi,
Listen, Sun doesn't know exactly what they are doing.
I installed the JDK 1.4.x on my machine b/c I need to
run this program for my Advanced Databases course. I
didn't install the JDK by choice. Now when I goto a
website that has a Java applet on it, IT DOESN'T
WORK!!!! It worked FINE with the JVM that Microsoft
provided in Windows XP! Further, Sun DOESN'T FOLLOW
the "Set Program Access and Defaults" in Windows XP
SP1!!! I change the default JVM to the Microsoft JVM,
reload IE, and then on the webpage it persists to use
the Sun JVM!
THANK YOU SUN FOR SCREWING WITH MY MACHINE! Have you got JRE1.4.x installed for the IE you are using.Download the java plug in for the browser and install it...
Regards

Hi,
I followed the instructions for the creating an applet and deploying it tutorial in JDEV 3.1.1.2. The applet works in the IDE but when I try to run it from the browser, IE just hangs and Netscape 4.7 gives a "Data Applet notinited" message.
In the example, the tutorial was ambiguous about whether the profile name should be different from the name of the profile for the application module since the default name in both cases was Profile.prf. I made the names different.
Is there something that I have to change in the html file?
Thanks in advance.
Petera file named swingall.jar is there in
jd jfc\lib directory.copy that file to
your applet html folder and add a proper
plug-in it will work.

Java Applets just stopped working on my machine the other day. They now persistently give me a "Failed to Load" message that says "Applet notinited" in it.
I've tried rolling back my machine before Tuesday's Windows Update, but it was VML-related, and probably not the cause of this (plus, the rollback probably would have fixed it if it were the cause). I also tried many different version of the JRE, and removed previous ones entirely before getting new ones. I've tried everything from the latest to older ones, and no luck.
I searched for this error, and Sun points you to proxy settings. Since I have no proxy, and since only my laptop, and not my wife's behind the same router, is affected, I know it can't be that.
Does anyone have any other clues? It's really annoying. And it seems to have happened completely out of the blue. I just can't use Applets any more. I changed no settings and messed with nothing. I'd hate to have to reinstall Windows just to fix Java.Hi, are you running a macmini Intel?
Launch the Console app [ Applications/Utilities/Utilities folder] do you have any message there regarding Java, and what are they if any?
I presume you have the latest Java updates, and have run your Software update to check?
Do you have these showing in the Safari menu bar under Help>Installed plug ins:
Java Plug-in for Cocoa
Java 1.4.2_09 Plug-in (Cocoa) — from file “JavaPluginCocoa.bundle”.

Did you recently update Java? see this from Apple.

IThank you!! The test account works. Now how to I fix my name account so it works, too?
You are welcome; ) If that doesn't help any...since this is user name account specific problem ONLY,as the test account indicates, see if the advice from Hayne his is post count 7 helps you any. I think it is worth the effort, you may also.
What does this Test tell you.
Does this work work for you showing a wavy? moving line of text
I don't know if any of this will help, I hope so. Good luck!
Happy Holidays to all here!
