Previously on the list, someone has told me that it is not working due =
to my HTML file needing a <applet> tag, not simply an <app> tag. This =
was corrected. Here is my new HTML file,
[------------------------------------------------------------------]
<HTML>
<HEAD><TITLE>Java Enhanced</TITLE></HEAD>
<HTML>
<HR NOSHADE>
<applet code=3D"HelloWorldApplet.class" width=3D50 height=3D50>
</applet>
<HR NOSHADE>
</BODY>
</HTML>
[------------------------------------------------------------------]
The source code is as follows:
[------------------------------------------------------------------]
import java.applet.*;
import java.awt.*;
public class HelloWorldApplet extends Applet {
public void init() {
resize(150,25);
}
public void paint(Graphics g) {
g.drawString("Hello World", 50, 25);
}
}
[------------------------------------------------------------------]
In HotJava, I simply get a red box, in Netscape nothing appears (except =
for the <HR>'s of course) and in AppletViewier, I get the following =
message at the dos prompt.
[------------------------------------------------------------------]
C:\PROGRAM\Java\Learning\Applets\ > appletviewer helloworldapplet.html

Can someone please help me out? The .java file compiles with no errors =
or warnings, and I can run other demos, \program\java\demo\* ...=20
