Applet not initialized, when I uninstall JRE1.4.1_24 on Win NT 4.0

We have uninstalled JRE1.4.1_24 from Win NT4.0 system and installed JRE1.3.1_08. Applet not initialized error coming up when the broser tries to open applet. Please help.

The Windows Java uninstall doesn't do a good job cleaning up after itself.
I ended up having to reinstall JRE1.4 to getting it working again.

Chat applet not initialized???

OS X on iMac...try to log in yahoo Chat but I get an error message " applet not initialized " I check every HELP suggestion but none will do nor does it properly address the issue. How does one initialize applet? Some say uninstall Java then re-install but OS X doesn't allow me to uninstall JAVA which came preinstalled. The funny thing is that the bottom portion of the yahoo chat site works but the chat area is blank.
Can anyone help? .Mac support guys are useless they only want money! they will not offer any assistance until a payment is made. Even then they can't guarantee anything. can anyone help me? I want to CHAT ON YAHOO.
David no say in yahoo.

Example settings for chat, based on Safari browser:
In Safari, select Preferences > Security > Web Content. Make sure the three check boxes pertaining to Java - "Enable Plugins", "Enable Java" and "Enable JavaScript" are active.
Some web chat providers also require that you install their client software.
Having never used such services, I do not know if this applies to Yahoo, or if they provide suitable client software for Mac OS X users.

"applet not initialized " error message HELP !

My applet compiles ok but when I try to run it at the bottom of the screen it says
start : "applet not initialized"
note - it works ok compiling from the Window console and then opening
the .html file in the browser, but when I try the same applet in the
BlueJ IDE ....that is when I get an error message.
Thank you in advance

//Place the sun and some brief instructions on the screen
public void begin()
sun = new FilledOval(100,150,100,100,canvas);
sun.setColor(Color.yellow);
new Text("Drag the mouse up or down", 20,20,canvas);

I put a start() around the begin() method
and a public void init() method around the onMouseDrag() method
but I am getting an "illegal start of expression" error message
Thank you for your advice

Java Applet not Initializing (LMS)

Hello everyone,
I have a small problem when trying to access a Java applet screen. When I open the applet, there are two different portions of the screen, a left window and a right window. In the left window, there is a caption at the top that says "LMS Initializing". There is supposed to be a list of hyperlinks that populate in the window, but they never do. It hangs on the LMS.
What is LMS? Something is blocking it's initialization. I have checked the manage add-ons menu and verified that the Java is plugged into IE, but I cannot seem to figure out the issue.
I do know of the following issues as well, and I have verified that they are not the problem here:
*Popup blockers
*IE security settings under the "Security" tab in Internet Options
*Secure Socket Layers
If anyone else can give me a boost here, I would appreciate it. Thanks!

did you restart the forms server with the command.

"Cipher not initialized" when trying to invoke CRM On Demand web service

Hi,
I'm try to invoke CRM On Demand web service for which there is a pre-req to get a session ID by making an https request. I've the below java embedded code which does that.

Same question...did you ever got this resolved...for me, even the simple java program, when run on JDev 11g is ALSO not working. I am getting this.
Using JDev 10g on the same machine (or for that matter SOA 10g) works perfectly.
Have posted this thread too - Getting SSLHandshakeException when trying to login to OCOD using Jdev 11g
Thanks,

Discoverer 4i Plus Applet not initializing Win2k/IE6 - Solution

Hi,
I finally got a solution to the problem of the Discoverer 4i Plus Applet not launching on IE 6.0 Windows2000 machines.
When you click on the image "Click to Start" the area goes grey and the applet never comes up. When you look at the java console you will notice a class not found exception. The reasons are as follows :
- IE 6.0 doesn't come with a built in JVM unlike the earlier versions. The JVM resides with the OS i.e. Windows2000 or WindowsXP.
- When launching the Discoverer applet you need to invoke the appropriate htm page
e.g. http://serverURL/discwb4/html/english/ms_ie/start_ie.htm
This htm page doesn't have any hint in the <applet> tag to use jinitiator or any other JVM to launch the applet, assuming that since the IE browser has an embedded JVM the applet will be launched. However this fails to happen since IE6.0 which ships with Window200 and Windows XP doesn't have a built in JVM. Why the JVM in the OS doen't take of that I don't know as yet. Therefore the applet fails to load and you get a class not found exception that can be verified thru the browser's java console.
- So instead of calling the IE configured page start_ie.htm call the corresponding netscape page like http://serverURL/discwb4/html/english/netscape/start_nn.htm. The start_nn.htm page has the appropriate <embed> tags to hint the initialization of the applet using jinitiator or other JVM. Therefore the applet gets launched.
Hope this helps all those who have had to face this issue.

Hi Simon
(4) Can I take the user automatically to the list of database workbooks ("Open Workbook from Database" dialogue box) without the user having to choose "Open an existing workbook" and "Database"?
Yes user can automatically view the workbooks or the worksheet or even a particular page of the worksheet.
Give the URL to the user and ask the user to run the URL from his/her browser. The URL shloud however contain the username, password, database name, workbook name etc...
This way we can bypass all the login screens and go directly to the desired page.
URL is as follows
http://hostname.domain/program_name/?us=APPS&db=devl&wb=Wb3&pw=apps
where
hostname.domain/program_name is where ur discoverer viewer is residing
us is the username
pw is the password
db is the database u wnat to connect to
wb is the workbook u want to open
Try this , this works.

Applett not initialized

I am running a web applicaiton on a windows xp machine and for this one particular user cannot open the application. I have tried logging him onto another computer and still get the same results. I have been able to successfully log on as myself and launch the program - so it must be somewhere in his user profile. But where? This is what the java trace says:

All instance variables are initialized...This is not a requirement of the JLS in all cases and cannot be relied upon when not required
if they are
primitives they are set to zero or "" if it is a
string.Strings are objects, in situation where a default is called for then null is used for all objects regardless of class.
All objects get their default constructors
called.No, there is no guarantee that a class has a default constructor available to be called, see the answer to your previous statement about default String assignment

Issue: 'Start Applet not initialized'.

I can't debug this program? Can you help?
Thanks!

When I compile the program, there's no bug. But when try to run it, it says "Start applet cannot be initialized".
Why is that? I'm new to Java..Maybe because the Class you are trying to run is not an applet? Possibly, but the OP posted the Account class, whereas the Start class has not yet been revealed. That is one of the reasons I suggested an SSCCE.
BTW I spotted a bug in your code above.You did. OTOH the OP has more imperative problems to fix, before they can 'understand the wisdom'(1) of your comment. ;)
1) By which I mean, see it fail for the reasons you outlined.I usually expect to find the context of a problem to be outlined in the form of an explanation or question inside a thread. I guess I should pay more attention to the title.

Java Applet not initiating

I'm new to Java and have been going through the SAMS "Teach Yourself Java 2" and have a problem will Applets. I am using the latest download of Java2SE (J2sdk1.4.2_09) and NetBeans IDE.
Creating Java programs works fine but when I do the exercise for Applets called "Palindrome" project, it fails. I embed the <APPLET> tag in my HTML a couple different ways laid out in the text but all fails. I doing this without the Internet. Is there something special that I need to do to get this to work with the generated palindrome.class on my hard drive.
I did make some changes to my computer's Internet settings based on an FAQ I saw on the Sun site - Proxy_Server - localhost. But this did not solve my problem.
I would appreciate any suggestions on how I might further investigate this - I'm sure I have something set wrong and just need some more test options to identify the problem.
Your assistance is greatly appreciated.
Thanks

Re: class can't be instantiated/ applet not initialized error

I would change the following:
From:
public abstract class AmazingApplet extends JApplet implements ActionListener
to:
public class AmazingApplet extends JApplet implements ActionListener
Also, since your class implements ActionListener, you must have an actionPerformed method (to take care of the addActionListener that you used all over the place.
V.V.

Thanks Viravan,
When I remove "abstract", I get the following error message:
AmazingApplet.java:7: AmazingApplet should be declared abstract; it does not define actionPerformed(java.awt.event.ActionEvent) in AmazingApplet
public class AmazingApplet extends JApplet implements ActionListener
Also, I do have actionPerfomed method in the program. Any suggestions?

Why is my applet not found when published by servlet-easy one?!

Hi! I have a servlet that publishes an html page with the applet tag inside it but it never finds the applet whenever it publishes the html. Can somebody please tell me where is the applet code supposed to be placed in jsdk2.1?! I placed it in the same folder as the servlets, as the .bat files, webpages, Web-inf but still it is not found. This is the Servlet code:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class chat extends HttpServlet{
     public void doPost(HttpServletRequest req, HttpServletResponse res) throws ServletException
          String user="",host="http://195.13.94.38/ChatApplet";
          try{ user=req.getParameter("user");
          PrintWriter output=res.getWriter();
          res.setContentType("text/html");
          output.println("<html><body><APPLET CODE="+host+" WIDTH=500 HEIGHT=400><PARAM NAME=user VALUE="+user+"></APPLET></body></html>");
          output.close();
}catch(Exception tru){}
I even tried to have the applet code= ChatApplet and still no success.
Thank you

I don't know if you fixed this already, but if you haven't, try:
String chat = "ChatApplet";
String codebase = "http://195.13.94.38";
out.println("<APPLET CODE=" + chat + " CODEBASE=" + codebase + " WIDTH= ........the rest of the code...>");
Give it a try and good luck.

Components and applet not loading when running the application using JVM1.3

I have my UI written in JavaScript.When I click a button,it opens a window showing the different components(images) and an applet containing a tree structure.The applet code is written in java
This is working fine and the applet is loading properly when I use JVM1.4. But there is a problem when I use JVM1.3.1_09.The images appear broken and the applet doesnot load.(When I click on one of the broken images,the images appear correctly but the applet still doesn't load)
Can anyone tell me what could be the reason behind this behavior??
My sys config: win2k-SP4, IE5.0-SP4

If you are using SDK 1.4 for compilation,
recompile your classes with the option -target 1.1
javac -target 1.1 MyClass.java

i tried putting the html file in the same
CyberPetApplet.class directory, but it doesnt
work.....You have to do one of the following.
1) Put your applet in a jar. Then you can put the jar in the same directory as your html page (or whereever you want to put it really). (This is the preferred method).
2) You'll have to put the class file in the right directory structure based on your package structure relative to your html file.
So in the directory with your html file you would have a directory named cyberpet with your applet class inside.
