Hi,
I just learned how to create applets and made my own ticker. It works fine
but when I try to integrate it to my struts 2 project I have problems
loading the page with the applet. It seems like my browser hangs and I need
to kill the process.
I first did was package my applet and its files in a jar and placed it in my
applets/ folder. Then on my page I had the following:
<applet code="TickerApplet.class"
codebase="${pageContext.request.contextPath}/applets/"
archive="ticker.jar">
</applet>
but my applet doesn't load because it cannot find the TickerApplet class and
my browser seems to hang.
I get the following error:
load: class TickerApplet.class not found.
java.lang.ClassNotFoundException: TickerApplet.class

I tried moving around my applet to the same directory as the page or just
use the class files but none of those approaches work.
Can anyone share any insight with my problem? Many thanks!
Look at the rendered HTML (view source) and check what's actually being
rendered as the value of the 'codebase' attribute. Does it look right?
What happens if you try visiting that URL? What happens if you append
'ticker.jar' to that URL? Does the JAR file download?
Assuming that's all OK, check the contents of the JAR file (use 'jar -t
applets/ticker.jar); does it correctly contain all your applet's .class
files?
