The "APPLET" Tag

Question

On the web site "http://geocities.com/xyz" I have the following files :
1. index.html
2. myJar.jar
2.1 mainClass.class
2.2 someOtherClass.class
2.3 pic.gif
In the index file, there is the following tag :
<code>
<APPLET code="mainClass.class" codebase="myJar.jar/" archive="myJar.jar" height=500 width=550></APPLET></code>
I get the error that the main class cannot be found

Answer 1

Codebase is a path from where the jre will start looking for class files or jars.
If I have a codebase value of "http://www.gecicties.com/hello" and a code value of
"hello.class" (no jars) than the jre will look for
http://www.gecicties.com/hello/hello.class
no matter where my page is even if it's started from the harddisk (like c:\myhtm.htm).
You can allso use relative paths in codebase for example:
my html file is in http://www.geocities.com/hello/htmlfiles"
the codebase is
../classes
the code is again hello.class
than the jre will look for
http://www.geocities.com/hello/classes/hello.class
The .. in codebase means 1 dir up so ../../ would mean 2 dirs up and ./ means current
dir.
If all the files are in the same folder I would suggest not using codebase at all and not
use the .class after the calue for code. It will look like this:
<applet
  code="mainClass"
  archive="myJar.jar"
  ...(the rest)
>
</applet>
