A Hello World JSP

• HelloWorld.jsp
• Note that this one is indistinguishable from static HTML
• The page is deployed by putting it in the web app's base directory
  • No compiling, no reloading the web app
• Here is the URL: http://redrock.d.umn.edu:8080/jspbook/HelloWorld.jsp
• When the page was first loaded, it was translated into a Servlet, and the Servlet was compiled and put into service
• The Servlet is stored in $CATALINA_HOME/work (several directories down)
• Here is the generated Servlet source file: HelloWorld_jsp.java
