How does HTML java applet finds its .jar?

Question

I have this code:

document.write("<APPLET CODE='com/synergex/My.class' ARCHIVE='toc2.jar' ");

When my "toc2.jar" is in the same folder as the HTML - all works fine.

But when I put "toc2.jar" in another folder ("C:\\MyJars"), I get ClassNotFoundException .

How can I "tell" the browser where to look for jars?

I tried to add "C:\\MyJars" or "C:\\MyJars\\toc2.jar" to my CLASSPATH env variable, but it did not work.

You might be able to redirect the code base using an HTML base element .

For example, given the following BASE declaration and A declaration:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
   "http://www.w3.org/TR/html4/strict.dtd">
<HTML>
 <HEAD>
   <TITLE>Our Products</TITLE>
   <BASE href="http://www.aviary.com/products/intro.html">
 </HEAD>

 <BODY>
   <P>Have you seen our <A href="../cages/birds.gif">Bird Cages</A>?
 </BODY>
</HTML>

the relative URI "../cages/birds.gif" would resolve to:

http://www.aviary.com/cages/birds.gif

If not, there are only 2 options.

Leave the Jar in the same directory as the HTML.
Presuming that part of the script is the only thing you cannot change, add codebase='../path/' immediately after it, to tell the JRE to wherever the Jar is located.

As an aside:

CODE='com/synergex/My.class'

Should be:

CODE='com.synergex.My'
