title: Adding external JAR´S to JDK
body: <p>I just started developing online applications using Servlets and JSP. As you may know we need a doPost method which receives HttpServletRequest req,HttpServletResponse res) parameters. </p>
  
  <p>My question is the following. I understand I need to import the javax.servlet and javax.servlet.http.* package in order for this to work. I remember once a this crazy teacher who told me I could modify my jdk/jre/lib folder and add those external jar which I would use a lot in order to forget about changing the class path every time I compile a project. Those anyone know how to do this? I already copy the servlet-api.jar into the lib folder but nothing happens..</p>
  
  <p>Thanks </p>
