Hello,

When it "meet" then <applet> tag in html code, could you tell me how a
browser do to "find" all the classes needed by the applet itself.
In my case, I run Firefox 2.0.0.4 under XP, with Java 5.
I have no CLASSPATH defined at all, no JAVA_HOME, nothing...

So I wrote a simple JTextPane swing applet, I call the .class into
html page.
I drag & drop this page into my browser and... everything work
fine !!!

(I know I could set ARCHIVE tag to add .jar file, but...)

Thanks for your help

Use Wassup to discover what system properties that control the
classpath. Basically it will be the same directory as where the HTML
file containing the <applet came from.

See http://mindprod.com/applets/wassup.html

Nearly always you don't have raw class files, you have a jar. The
archive URL can fetch the jar from anywhere. This makes it much more
flexible. You can invoke the Applet from anywhere on your website.
