The JavaServer Pages technology is an ideal way to describe processing of XML input and 

output. Simple XML generation can be done by just writing the XML as static template 

portions within the JSP page. Dynamic generation will be done through JavaBeans 

components, Enterprise JavaBeans components, or via custom actions that generate XML. 

Similarly, input XML can be received from POST or QUERY arguments and then sent 

directly to JavaBeans components, Enterprise JavaBeans components, or custom actions, or 

manipulated via the scripting.

There are two attributes of the JSP technology that make it specially suited for describing 

XML processing. One is that XML fragments can be described directly in the JSP page either 

as templates for input into some XML consuming component, or as templates for output to 

be extended with some other XML fragments. Another attribute is that the tag extension 

mechanism enables the creation of specific actions and directives that are targeted at useful 

XML manipulation operations.

Future versions of the JSP specification may include several standard actions that will 

support XML manipulation, including the transformation of the XML produced by the given 

JSP page using XTL/XSL.
