1.1.2 Practice lab: using JSP on embedded Tomcat in NetBeans
First, Download the NetBeans from http://www.NetBeanss.org/, the current version is 6.0
After install the NetBeans, you start up NetBeans IDE, and you should see the NetBeans start page as
follows.




Once you installed the NetBeans, the Glassfish v2.1or Tomcat 6.0 can be chosen as the default Server


Steps to Start a Web Project:
Let’s practice the NetBeans IDE with following steps to create a new Web project. In this application
Tomcat 6 is used as the server.
In first step, select File->New Project, and Web->Web Application.
Next, specify the project name and project location in step #2 of “Name and Location”




Skip step #3 Framework selections for the time being.
In the file explorer, select Application name->web->index.jsp, and now let’s do some modification to this
template file.
Copy the following code in the body tag:



<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">

<html>
 <head>
    <title>Hello User! JSP Page</title>
 </head>
 <body>

 <form name="name" action="index.jsp" method="POST">
    <input type="text" name="name" value="" />
    <input type="submit" value="submit" name="submit" />
 </form>


 <%if(request.getParameter("name") != null){%>
 Hello, <%=request.getParameter("name")%>
 <%}%>
 </body>
</html>

Press Run Main Project (F6), The NetBeans will run Tomcat server and you can use browser to visit
localhost to access this JSP file:




If you type in “John” in the text box and then submit the request a new JSP page is generated with the
greeting statement of “Hello John”.
