Installing Internet Component

[Phthora]

I have a package of Java classes (one of which is an applet) that I want to install on the client's machine. Since this project will be accessed only by IE browsers, the solution is to create a .cab file. Since I want these classes to be permanantly installed, I built the .cab file with the dubuild utility. I then signed them with a test certificate, providing the necessary permissions. I then followed Microsoft documentation and inserted the following HTML code to download and run the cab...

Here's the issue. I get the Security Alert asking if I want to install the cab file, I click yes, it installs it (I verify this by checking the downloaded program files and viewing the objects stored in the temporary internet files), but then it always says it can't find the applet. Here's the HTML code, but I'm really unsure of where the actual problem lies...

<applet code=HIS.EmailSending.Filler width=300 height=200>
<param name=namespace value=&quot;HIS&quot;>
<param name=useslibrary value=&quot;TestCAB&quot;>
<param name=useslibrarycodebase value=&quot;testCAB.cab&quot;>
<param name=useslibraryversion value=&quot;2,0,0,0&quot;>
</applet>

Filler is the name of the applet that should be displayed, and does reside in that package. And yes, I know the package has been properly installed (including path information) by checking the downloaded program files and viewing the objects in temporary internet files.

Why won't the applet show??? It's as if it's just not finding that which it just installed.
