From my understanding, JSPs are compiled anyway, so I would anticipate you'd get similar performance from both. I want to display a lot of data, and I'm thinking of using JSP for the basics and calling a servlet to generate the code for each row in the table. Unless there's a good way to generate the entire table with one call to the s...
