Running Applet on Browser

plz tell me how to run an applet on the browser.
i have the applet.java file and also created the applet.class file .
i have the applet.html file and all the 3 files are in the same folder .
how to display the applet contents on the browser now.
i tried with
appletviewer applet.htmlbut this throws
java.lang.NoClassDefFoundError:

Just add this to your HTML code:
<applet code="codename.class"></applet>.
Put the name of your applet instead of "codename.class".
You can also add height and width attributes to the applet, and you can also put text inside the applet, so if the person does not have java, he or she will see the message.
i.e.:
<applet code="codename.class" height="100" width="100">Not loading? You might need to download java.</applet>

How to switch between jre 1.5.0 and 1.4.2 when running applet in browser?

Hi,
I have JRE 1.5.0_05 and 1.4.2_04 installed and currently applet in browser is always run under jre 1.5. How to run the applet under jre 1.4.2 in browser?
Thanks a lot

Hi,
Thanks for the info. I was thinking that the note didn't work for me, apparently I didn't use the conventional APPLET tag.
Is there other way to switch JRE if I'm not using APPLET tag?

HOw to run Applet in browser.

Hi guys. I've got 2 problems.
1. In Window, I've got Java installed (and using NetBean IDE as Java editor), so of course I've got j2sdk_nb-1.4.2 installed as well. But I couldn't run any applet in IE, for example, in games.yahoo.com, I couldn't join any game because applet always failed to load. But yesterday, I've got a pop up asking to install jre1.4.2 and after install this JRE, everything works fine. My point here is, when I have SDK1.4.2 which contains JRE, why should I have to install new JRE to run applets ?
2. Could anyone tell me how to run applet in Mozilla, Linux. I'm using Linux RedHat 9 as well. And in Redhat, I've got J2sdk_nb-1.4.2 installed with NetBeans IDE. It said that I need appropriate Plugs-in, but in my Java directory, I also found Plugsin directory. So how to configure Mozilla to run applet.
Thanks for reading.

Just to let you guys know that I sorted it out already. Well, the problem lies in I'm confused between two directory /usr/lib/Mozilla and /usr/lib/Mozilla and two Java plugs-in available in nsc60 and nsc60-gcc (don't remember exactly)
For my Linux (Red Hat 9), I've got to create symbol link from nsc60 directory to /usr/lib/Mozilla, not any other way.
Thanks

Run applet in browser when html file is stored in different dir.

I have a SiteSelector.class stored in: "D:\DATA\Java Programmes\Networking\"
and a SiteSelector.html stored in :"D:\DATA\Java Programmes\Networking\HTML files\"
Here is a part of the code of SiteSelector.html:
<applet code= "SiteSelector.class"
width=500
height=500
codebase="D:\\DATA\\Java Programmes\\Networking\\"
archive=""
alt="Your browser understands the <APPLET> tag but isn't running the applet, for some reason."
>
<param name = "title0" value = "Java Home Page">
          <param name = "location0" value = "http://java.sun.com/">
<param name = "title1" value = "Deitel">
          <param name = "location1" value = "http://www.deitel.com/">
          <param name = "title2" value = "JGuru">
<param name = "location2" value = "http://www.jGuru.com/">
<param name = "title3" value = "JavaWorld">
<param name = "location3" value = "http://www.javaworld.com/">
Your browser is ignoring the <APPLET> tag!
</applet>
Since html file and .class file are stored in different directories so in applet tag I specify absolute url in "codebase = ......" to indicate that the browser should look for .class file in "D:\DATA\Java Programmes\Networking\".
But when I run the Applet in the browser, nothing happens. But when I copy the html file back to "D:\DATA\Java Programmes\Networking\" and change the codebase = "D:\\...." to codebase = "." It works well. Any one can help me to hanld this problem. I want to run the applet in the browser when the html file is stored in different directory. Thank you.

Run applet from browser

I cannot run the applet from explorer ?! I'm trying to open the html (applet).

Perhaps, you use Swing library and your browser don't support JDK more than 1.1.
May be, your applet can not find additional classes.
Check it, and also applet tag in HTML page.

Running Applet without Browser

Hello All,
I've developed a test applet which contains a button.
When i click the button a Frame opens and does whatever i try to do,
Thus,to Run my applet i type the URL in the Browser and click the button to open the Frame.
My Problem is the Frame is destroyed as soon as the browser is closed!
I need the frame to be browser independent.
Could anybody suggest me how this would be possible?
Thank you!

Applets are intended to be run in browsers.
There is a program included with the JDK that can run an applet - look for the appletviewer program. There are insructions on its use in the Java tools documentation.
It sounds like you should be running a Java application, not an applet.

Applet not running in local browser

I can run any applet from web.
I can run any applet in appletviewer.
But I can not run applets in browser from local html file.
I can not run even the demos that came with de SDK 1.4.1_01.
Can anyone give me some hint?
Maybe is very obvious but I ca not see it.
Thank you very much.
Valeriu Sprintu

the hello.java file is:
import java.applet.Applet;
import java.awt.Graphics;
public class hello extends Applet {
StringBuffer buffer;
     public void init() {
     public void start() {
     public void stop() {
     public void destroy() {
     public void paint(Graphics g) {
          //Draw a Rectangle around the applet's display area.
          g.drawRect(0, 0, size().width - 1, size().height - 1);
          //Draw the current string inside the rectangle.
          g.drawString("Hello", 5, 15);
The hello.html file is:
<html>
<body>
Applet should be there
<br>
<applet code="hello.class" width=200 height=200>
No applet
</applet>
</body>
</html>
hello.html and hello.class are of course in the same folder.
If I modify the .html file acording to OBJECT tag specifications for Java Plug-In the same applet runs OK in the browser (IE5.0 ).
I forgot to tell that I have installed the last version of SDK j2sdk1.4.1_01
<html>
<body>
Applet should be there
<br>
<OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93"
WIDTH = 200 HEIGHT = 200 >
<PARAM NAME = CODE VALUE = "hello.class" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.1">
No applet
</OBJECT>
</body>
</html>
I think there is a problem with the JVM from Microsoft
Thank you,
Best regards,

Run applet on wireless browser

A liitle help please :)
I do lots of java apps but this is my first foray into the wild and woolly wireless world. . .
I have a web app the runs an applet in the browser. I need some help in figuring out how to enable this applet to run on a browser for a wireless device.
Thanks!

Applet needs Java SE runtime Env.
Most device in wireless world don't support j2se but also java ME.
In order to run an applet on a browser for a wireless device you must find a device that support java SE.

Running forms within Browser, not as applet

I am running Developer/2000 Form Builder for Windows 95 / NT and application server 4.0.7 using the JInitiator. I want to run my form within the browser
window and not as an applet. I already tried the separate frame=false property in the html source, but that did not work for me. I would
appreciate any assistance.
Thanks,
Bucky

Forms 4.5 only ran outside the browser.
Forms 6i can run in the browser.
check out the first demo at
http://otn.oracle.com/sample_code/products/forms/content.html
to see how it looks.
You should upgrade to the newer versions of forms if you are planning to run on the web since there were many improvments in those versions for Web deployed forms.

How to run applets ?

I know 3 ways to run an Applet .
1.to write html file and include aplet in that file and run in a browser .
2.run appletviewer cmd from cmd window
3I use text pad as a n editor which has tools to compile and run and while running automatically .
if there are any other ways do tell me and also which one of these is a better way to run an applet?
thanks

which one of these is a better way to run an applet
Well normally you put a applet on a webpage,so I would say that would be the best way to run the applet since that is where it is going to be used.

How to Run Swing in Browser

Hi frnds
I gotta a Problem in swing.I want to run my swing in Browser.I have tried it with JApplet.But i can execute it only in Console.using appletviewer <filename>.html
how to run it in browser.
Please Help Me..

Quite easy, well for you. You have to have the newest java plug in working in your browser, but as a flaw, if a user wants to access it they need to download it too, but there is a way in the new JDK i believe to have the JRE on Suns server to run the applet, so the user w/o the Swing librarys can use the applet w/o problems

Run applets without JRE

Hello to all developers,
I know that to run applets in IE we should have the JRE installed on our machines. But is there any way that we can run applets without the JRE being installed on our machines. I have also heard of something called as the Microsoft JVM. How can we use it to run the java applets.
Thanking in advance.

The Microsoft JVM is extremely outdated and not recommended at all. You can't really run a Java applet without a JVM, and I'm not sure if any but the one Sun makes comes with a browser plugin.
