Question

what is difference between JspWriter and PrintWriter ?

Answer 1

From the javadoc:

This abstract class emulates some of the functionality found in the java.io.BufferedWriter and java.io.PrintWriter classes, however it differs in that it throws java.io.IOException from the print methods while PrintWriter does not.

The JspWriterImpl of tomcat delegates the writing to the PrintWriter obtained from the response.
