Editing JHTML (section)

== Overview ==
When a request is made for a JHTML page, e.g. "index.jhtml", the request for this page is forwarded from the [[HTTP server]] to another system running a [[Java application server]]. The JHTML page is compiled first into a .java file and then into a Java .class file. The [[application server]] runs the code in the .class file as a servlet whose sole function is to emit a stream of standard [[HTTP]] and HTML data back to the HTTP server and on back to the client software (the [[web browser]], usually) that originally requested the document. The principal benefit of this system is that it allows logic running in Java on the application server to generate the HTML dynamically. Often a [[database]] is queried to accumulate the specific data needed in the page.

The system is derived from earlier forms of [[Common Gateway Interface|CGI]] programming that allow a program running on a web server to generate HTML dynamically. With JHTML, you can author standard HTML and just insert a few extra tags that represent the pieces of the HTML page data that Java should be used to create. JHTML is a proprietary technology of ATG. [[Sun Microsystems]] licensed parts of this technology and developed the [[JavaServer Pages|JSP]] system from the ATG page compilation system.
