Tomcat Interview Questions and Answers

Question: What is Jasper?

• Jasper is Tomcat's JSP Engine. Tomcat 5.x uses Jasper 2, which is an implementation of the Sun Microsystems's JavaServer Pages 2.0 specification.
• Jasper parses JSP files to compile them into Java code as servlets (that can be handled by Catalina).
• At runtime, Jasper is able to automatically detect JSP file changes and recompile them.
