JSP stands for JavaServer Pages and is a server-side web programming language that can be embedded within HTML and it is used to create dynamic web pages or web applications. JSP code is interpreted by the web server which then outputs a web page to the browsers that access it. JSPs can be compiled on-the-fly into Java Servlets by a JSP compiler.
JSP can be used on almost any platform using Apache Tomcat. JSP can be used for managing email, connecting to other web sites or servers, processing form information, storing information in a database, creating cookies in a web browser, and much more.
Syntax is the wording and way that the language has to be used for it to work. PHP is very flexible so it is a great language for beginners to start learning how to program. JSP is very similar to a normal Java program. JSP variables are strongly typed. Here are some important things to learn about JSP:
JSP supports most of the same functionality that Java does including functions (blocks of code that can do specific things over and over) and objects (groups of functions that represent real-world objects like a book or a user). You can code JSPs in any text editor but there are many editors, such as Eclipse, that support syntax highlighting and other features. What does JSP code look like? Here is a sample:
<%@ page errorPage="myerror.jsp" %>
<%@ page import="com.foo.bar" %>
<%! int serverInstanceVariable = 1;%>
<% int localStackBasedVariable = 1; %>
<tr><td><%= toStringOrBlank( "expanded inline data " + 1 ) %></td></tr>
If you are interested to learn about JSP, we recommend reading the JavaServer Pages Documentation. For a gentler introduction, you can try JSPTut's tutorials, or read Sitepoint's Java and J2EE articles. We also recommend using a book from the library or one of the following:
