[wxdqz]

im a bit new to java and i just started using visual cafe.i downloaded the a java package (saxon xslt processor). it was one zip filebut when i extracted it to some folder on my desktop, it put out two direcotries(docs and src) and a saxon.jar file.how can i refernce the classes within it. for instance when u use the standardclasses, visual cafe brings up a little box to show u the mehtods or subclasses of the particulr class. i want to make the saxon files do the samething.how ? thankx
