Anywhere you like.

1. Add the directory which contains your class, or your classes root package 
if it is in a package, to your CLASSPATH. (you probably need to restart your 
servlet engine to get it to pick up this change).

2. This step is only needed if your class is in a package, and you don't 
want to have to type in mypackage.mysubpackage.myclass repeatedly, but 
instead would like to just type myclass: Put this before your page root 
element, but inside your xsp:page element:


3. Call your class inside your page root element.

  // Just normal Java code goes here
  MyClass x = new MyClass ();
  x.myMethod ();
  // ... etc

and to insert results into the output for them to be matched by XSLT:

<file><xsp:expr>myobj.getFile ();</xsp:expr></file>

I'd personally advise you NOT to base your XSP on the clean-page.xml sample, 
as this uses a deprecated technique and is confusing for the first-time 
Cocooner (it was very confusing to me!)
