REDemo.java doesn't seem to work as an applet

Hi,
According to the javadocs, REDemo.java is supposed to be an interactive
demo and testing facility.

I compiled REDemo into a class file with no problems, then created a
test.html with an <APPLET> tag referencing REDemo.class.

I use appletviewer on test.html and I get the following "wrong name"
error:

I am pretty sure I set the classpath correctly.   Anybody have any idea
why REDemo.java doesn't work.

Thank you for your time.

Sincerely,
Stephen

Hi again,
It still doesn't work.  Error message below.

My classpath has "C:\jakarta-regexp-1.1\src\java" beacuse the
REDemo.java is a package of "org.apache.regexp"

I've tried the following applet tags:
<applet code="org.apache.regexp.REDemo.class" height="400"
width="400"></applet>
<applet code="org.apache.regexp.REDemo" height="400"
width="400"></applet>
<applet code="REDemo" height="400" width="400"></applet>
<applet code="REDemo.class" height="400" width="400"></applet>

I either get "Wrong name" or "can't find file" errors.

Am I missing something here?

Thank you.

Sincerely,
Stephen

The class name is "org.apache.regexp.REDemo", not "REDemo".  That is
the root of your problem.

REDemo has "extends Applet" and implements TextListener.
I have to rewrite REDemo.java?

Thanks.

I just run it from the command line as an application instead of an applet.
