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 :D
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:
