    Question OBJECT tag

    I'm still having trouble grasping how this thing is supposed to work. I've read numerous tutorials on it and I'm still lost.

    I wrote a stupid applet that simply prints a string to the applet. I made a web page that uses the OBJECT tag to display it on the web page. Here is the code that I used:

    Code:
    <html>
	<head>
		<title>Keyboard Test Applet :: Written by Greg Martin</title>
	</head>
	<body>
		<center>
			<object classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" codebase="http://java.sun.com/products/plugin/autodl/jinstall-1_4_2-windows-i586.cab#Version=1,4,0,0" width="640" height="480">
				<param name="code" value="KeyboardTest.class">
				<param name="codebase" value="html/">
				<param name="type" value="application/x-java-applet;version=1.4">
			</object>
		</center>
	</body>
</html>
    This works all fine and dandy however the applet window keeps telling me that the applet failed to initialize. I might be missing something because of it's absolute simplicity but here is the code that I have in the applet:

    Code:
    import java.applet.*;
import java.awt.*;

public class KeyboardTest extends Applet {
	public void init() {}

	public void paint(Graphics g) {
		g.drawString("Press a key...", 20, 20);
	}
}
    The KeyboardTest class file is located in the same directory that the web page is in so I don't see any problem there but I can't figure out what in the world is going on. Any help would be appreciated. Thanks in avance.

    EDIT: And yes I am aware that the class id for the version of Java is lower than what's available but I figured that since I used dynamic versioning, it'd find the more recent one until I figured out how to properly use the OBJECT tag.

    Re: OBJECT tag

    try
    HTML Code:
    <param name="code" value="KeyboardTest" />
    remove the .class from the value

    And if the class file is in the same path as the web page, you should set
    HTML Code:
    <param name="codebase" value="html/" />
    value to empty string ""

    Re: OBJECT tag

    I did what you said to do but it's still saying applet uninited. I really do think that it's finding the applet class code regardless of if the extension is there or not. And as far as I can tell, there isn't anything wrong with my applet code. I can't figure out what's going on here.

    Re: OBJECT tag

    Try including:
    Code:
    srctype="application/x-java-applet"
    in your Object tag as an an attribute, not just the param.

    Re: OBJECT tag

    I did that and it still can't initialize the applet. I thought that it might have been the JRE itself so I reinstalled it and it was still doing it. I copied what the Java Console wrote out and here is what it said:

    load: class KeyboardTest.class not found.
