Java Server Pages is a server-side language that uses simple tag-based codes inserted into HTML and XML to produce dynamic and interactive web pages that are platform independent, meaning that by all rights they should appear exactly the same on every computer screen, regardless of the platform. This is the result when your publish yoy JSP-coded website on a JSP-supported Java hosting provider.

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: <jsp:action> 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.

Cold Fusion hosting adds versatility and interactivity to ecommerce sites. Cold Fusion allows you to publish and then have automatically removed from your site time-sensitive content, such as flight schedules or event calendars. It adds functionality to creating and managing mailing lists and business reports. It allows you to offer your visitors printable content and customized menus.

Anytime you see .cfm as the extension on a web page, as opposed to .htm or .asp for example, you know you’re dealing with Cold Fusion Markup Language (CFML).

Though cold fusion is built on the Java platform, CFML allows web developers the benefits of Java without its inherent technical complexities. You need not know Java scripting in order to use cold fusion. CFML is a tag-based language quite similar to HTML and XML which makes it easy for anyone with even the most basic knowledge of web scripting to learn.

Cold Fusion is a server-side language which means that any web pages using CFML are read and interpreted by the Cold Fusion hosting company’s server and converted into an HTML page prior to being sent back to the user’s browser.

Cold Fusion web hosting can be significantly more expensive than other forms of web hosting, and should therefore only really be considered if its unique set of tools are relevant for your site’s intended uses. Cold Fusion hosting is usually run on Windows 2000/NT/2003 operating systems, though you can also find support for Cold Fusion hosting on Linux and Sun servers.

In addition to all the usual factors you must consider when choosing any web host – cost, disk space, bandwidth, uptime, scalability, support – you now also have to consider certain factors specific to cold fusion hosting, including: potential tag restrictions, additional security concerns, whether the cold fusion hosting company provides database support, and which version of Cold Fusion they’re using.

One type of tag restriction that is also a security concern is “high risk” tags, such as those that can be used to find and erase selected files from a server. For some larger businesses, this functionality is crucial to their operation, though potentially detrimental if accessed by the wrong hands, in which case a dedicated server is probably in order. Fortunately, cold fusion hosting is offered on shared, virtual, and dedicated servers.

Cold Fusion is well worth considering if you’d like the functionality of the Java platform with the facility of a comparatively autonomous and user-friendly software system. Especially if your website is expected to generate an income, you may find that the intimidating price tag, in the long run, turned out to be a bargain.
