BSF makes this pretty easy, but it's not ideal. Mainly because you ruin 
separation of concerns by plugging exec/evals into a jsp mess.  While I 
originally liked this idea, it turns out to be a maintenance mess!  I've 
been away from it a bit so I have only a little progress here, but a 
better plan is to support jython classes right in MVC rigs like velocity 
(turbine), webmacro, freemarker (maybe struts, but I don't know much about 
it).  This way there's not really code in templates, and Jython classes 
handle non-visual grunt work.  This does more for web development with 
Jython than an exec/eval in jsp.
