title: Difference between servlet API and servlet and JSP API?
body: <p>I have been making JSP and Servlets in NetBeans without adding this servlet API or JSP API why do I need to add it in my project library folder, if the same is available in my local server Tomcat/Glassfish or in the Web server I upload the files to. Already Netbeans Servlets are working without adding these extra libraries right?</p>
