Java Applet

**eranga262154** · Sep 8th, 2006, 11:29 PM

Hey....

I have created very simple Java Applet. Here the coding has done my-self.

This is the Java File.

import java.awt.Graphics;

public class HelloWorldApplet extends java.applet.Applet
{
public void paint(Graphics g)
{
g.drawString("Hello World",5,25);
}
}

This is HTML File.

<html>
<head>
<title>Hello To Everyone !</title>
</head>
<body>
<p>My Java Applet Says:
<applet code = "HelloWorldApplet.class" width=150 height=25></applet>
</p>
</body>
</html>

Then I used IE6.0 and Applet Viewer to run the applet. But it gives different outputs.

Output on IE6.0 and Applet Viewer as follws.

I’m confusing with that. Can someone help me to where I’m going wrong?

Please use code tags whenever posting code.

I don't think IE supports the applet tag, or if it does, it might attempt to use the broken MS JVM.
Use the object tag with the correct classid instead.

You can Open Java Console from the IE page (Right click the Applet) and check if any errors occurred during run-time

EDIT: CornedBee is %100 right, you should use the Object tag

Please can you explain this little.

Thanks

Which part, the first or the second?

Look for a little mug of coffee in your taskbar. Right click and view the console. Any errors will be listed there.

PS: What about a screenshot of these differences... Applet tag has always worked for me (cross browser), so I'm not sure what kind of problems you're having.

Sorry about that, you did post screenies.

It looks like IE doesn't have an updated JRE or something. Goto internet options and make sure the java checkbox is checked. If it is checked, then uncheck it and try again (make sure you check it back if this does not work).

That's right, you can make sure java is enabled for any browser from the Java shortcut on the Control Panel
Java==>Advanced Tab==>Settings==> <Applet> tag support.
If you didn't have any of these you must re-install the JRE

I go through your link,

But still comes with same output,

My output should be as follows.

My Java Applet Says: Hello World

That bold text should be printed on a dark area, isn't it? Still have the same output.

if you couldn't find out what is wrong, please show us the stack-trace of the Exception

**eranga262154** · Sep 13th, 2006, 10:41 PM

OK,

holdon, I'll test it and send my response here. Thanks

It could be that your browser does not have legacy support. When you set attributes, they should be in quotes:

<applet code = "HelloWorldApplet.class" width="150" height="25"></applet>

Also, make sure that your setting your page color so that it draws in black (or whatever color you want).

Code:

g.setColor (Color.black);
g.drawString("Hello World",5,25);

It's good programming to set the color before you draw anything, even though it should draw in black by default. You may consider setting the background color before you draw to see if that even shows up when viewing from IE.

Code:

setBackground (Color.blue);
g.setColor (Color.black);
g.drawString("Hello World",5,25);

It's poor programming (Lack of efficiency) when you put unnecessary instructions in your code

Welcome to the world of XHTML. Read up on it. Most browsers are phasing out HTML support, and the new standard is XHTML. It is considered good programming to put attributes in quotes, though in basic HTML it is NOT required. Make sure you know what your talking about before you post false information.

(It didn't quote your statement about my comments on quotes correctly)

**ComputerJy** · Oct 9th, 2006, 01:55 PM

Perhaps, you'd go and read my post again.
About the XHTML I just said "No you don't", and you really don't have to write XHTML, HTML still works for all browsers

The Part you quoted was about the "setColor" which is totally unnecessary

Browsers phasing out HTML? What planet do you live on? XHTML has huge acceptance issues. IE still, even in version 7, doesn't really support XHTML. XHTML 2, from what I'm seeing on the W3C html list, is in high risk of being stillborn. The W3C itself is being criticized by many professionals, and the WHAT-WG is busily writing a HTML 5 standard.
I give HTML another 10 years at least, unless virtual reality becomes the primary net form first.

I try this, but not get fine output. I think misses the quotes is much effected to my code, isn't it?
