JavaBY Template Engine is a general template engine used for generating any type of text document from a template. JavaBY Template Engine is used mostly for generating HTML from servlets(JSPs) but it can also be used for generating XML, RTF, WML, e-mail text, source code and configuration files.
Template has existed in different forms for several years, its concepts are proven, its implementation is robust and it performs well.
Using JavaBY Template Engine in cooperation with Java Server Pages instead of standalone Java Server Pages means that you can completely separate your content from your markup, as the originators of markup languages intended.
The difference between JavaBY Template Engine and JSP is that content can be generated outside a webserver and that the layout is completely separated from the application code.
JavaBY Template Engine defines a well-formed tag language. There is no scripting language involved. No calls are made from the template to the application and no calls are made from the application code to the template. The result of this is that an application becomes easier to maintain and you get a higher degree of reuse since the same template can be used with different application code and the same application code can be used with different templates.
