access java from xslt

I have seen the following example for accessing a Java  class from inside
XSLT.

<xsl:variable name="date"
 select="Date:toString(Date:new())"
xmlns:Date="http://www.jclark.com/xt/java/java.util.Date"/>

There also used to be an article on
www.xml-zone.com/articles/vp0801/vp0801-1.asp   but it is no longer there.
The code seems relatively straight forward but I am having the worst time
trying to access an class that I have created. Has anyone done this who
could provide some guidance?

Thanks.
