Java Applet not working in web browser

C

Cyron

Hello,

I've developed a simple Java Applet using Eclipse -- it works just
fine from within Eclipse, but I can't get it to render from within a
web browser. I have copied the following files into a folder:

index.html // the webpage i'm trying to view the applet from
CheckIt.class // the applet file produced by Eclipse
java.policy.applet // another file that came with the .class file.

The contents of my index.html:
<html>
<body>
<APPLET CODE="CheckIt.class" WIDTH=900 HEIGHT=900 />
</body>
</html>

When I launch index.html (this is all done locally), the page appears
as if the Applet wants to load, but nothing happens -- I'm just left
with a gray region according to the width and height dimensions I
specify in index.html

The web browser will successfully load other applets from the web, so
I know that it is configured properly -- for some reason it doesn't
like mine (which is magnitudes simpler than the ones I view on the
web). Any clues as to what is wrong?

Thanks,
Mike

There is no such thing. The only simple projects
run headless (no GUI), and applets embedded in a web
page add a whole new (and exciting) level of problems.

Having experience with both applets, and separately
frames (and applets) launched using web start* (from
a browser link), I would recommend web start and frame.

I there any reason this little project needs a
browser wrapped around it?

How doe eclipse run the applet? Does in invoke
the JDK's AppletViewer?

Do you pop your browser's console?

Are you AKA 'Willy Stevens'?! That is the second
reference to policy files in regard to applets that
I've heard today!

* For some examples of apps. launched using
web start, see <http://www.physci.org/jws/#apps>

follow the recipe at http://mindprod.com/jgloss/applet.html

If that does not work, turn on the Java console. The error message
will give us a much better clue what the problem is.
