Where to install Sun AppServer 8.1?

[Leo]

Dear All,

I want to install Sun AppServer 8.1. The current version is 8.2. The
reason is that Sun AppServer 8.2 stops to include PointBase, while
version 8.1 includes.

The books I have need to use PointBase. In order to follow the material,
I need pointbase. I have installed PointBase from www.pointbase.com. But
it is installed in different places and the sample code from my book
doesn't work anymore. And it is hard for a beginner like me to correct
the sample code.

Could anybody help me to find how to install Sun AppServer 8.1?

Many thanks.
