Java Servlets example using NetBeans 6

1. Java Servlets exampleusing NetBeans 6

2. Pre-requirements: • Install Java JDK 1.6 • Install NetBeans IDE 6 (we will use version NetBeans IDE 6.7.1 update 16) • Remember to choose the setup of a web server (GlassFish with GlassFish prelude, Apache Tomcat or both)

3. Create a Web Application • File -> New Project -> Java Web -> Web Application • Click Next, choose a name and a location for the project. We will call it ITShop • Click Next, Choose the Server that you want to use (GlassFish or Apache Tomcat) • Click Finish

4. Build the home page • An ‘index.jsp’ page is created automatically. Write whatever html code you wish in it. You can also use the tools from the palette on the left. • We will write some hyperlink that will call the servlet and pass a value to its doGet method. • We also will put a form in that page that includes a text input, a submit button and a reset button.

6. Create the servlet • Right click the project -> New -> Servlet... • Choose a name for the class (we will call it ‘PageCreatorServlet’). Click Next, choose a name for the servlet, (we will use the same name). Note that the check box of ‘Add information to deployment descriptor (web.xml)’ is checked. • Click Finish

7. Edit the servlet • The ‘PageCreatorServlet’ will be created automatically, including its doGet and doPost methods. It also includes a ‘processRequest’ method that will be called from the doGet and doPost methods. • We can write our implementation in the doGet and doPost methods. But instead, here we will write in the processRequest method.

9. Note: • You can run the servlet alone for testing purposes instead of runing the entire project. • Right click the servlet -> Run File. You can also add some parameters to the servlet execution URI (for example: /PageCreatorServlet?DATA=“SW”). • You can also change this execustion URI. To do so, right click the servlet -> Tools -> Set Servlet Execution URI • Run the project and test it.
