JSP allows web designers combine dynamically generated HTML in with their standard, static HTML code. While most CGI programs require you to compose the entire website in that one program, JSP allows you to compose the dynamic aspects and the static aspects of your site separately.
Java Hosting which includes JSP support would be the logical choice of any web designer wishing to eliminate the irritating need to repeat work they've already done. Java hosting, and JSP hosting specifically, would also be an efficient choice for those web designers working with a team.
One of the greatest aspects about JSP is that you don't need to learn Java to use it and it’s practically built into programs like Macromedia Dreamweaver MX.
JSP's use a variety of simple tags. The following are some of the most basic and common ones:
* Directives: <%@directive%> Instructions processed when the page is compiled
* Hidden Comments: <--comment--> Document the page, not sent to the client
* Declarations: <%!declaration%> Declare methods or variables with scope throughout the page.
* Expressions: <%=expression%> A bit more complicated to explain, expressions produce results which are then inserted into the output stream at the appropriate place
* Scriptlets: <%scriptlet%> A fragment of code that can access a declared variable and execute it at a defined time.
* Actions: An XML-style tag that can perform any of a slew of functions
So if you are running JSP, remember that you need to have a host that provides JSP runtime modules on the host side of your web server so that you can run the appropriate scripts.
