The first JSP

Java Server Page is a web page document that integrate Java codes to generate a dynamic content. In this tutorial we will create a simple JSP that show the current time.

Open Eclipse, create a Dynamic Web Project, name it jsplabs and set Target runtime as Apache Tomcat v7.0.
Right click on the WebContent folder, select New→JSP file.
Name it first.jsp and click Finish

Insert the following codes between the <body> tags:

<h1>Fist JSP</h1>
<ul>
<li>Current time: <%= new java.util.Date() %>
<li>Server: <%= application.getServerInfo() %>
<li>Session ID: <%= session.getId() %>
</ul>

Save the file.
Right click on the first.jsp file, select Run As→Run on Server.
Select your Tomcat server and click on Finish.
The file first.jsp is automatically opened on your browser at the URL: http://localhost:8080/jsplabs/first.jsp.
