class provides information on the JSP container implementation. The
only method currently available is:
Returns a String in Dewey decimal describing the highest version of the JSP
specification implemented by the JSP container. See the
class in the Java 2 platform for other methods that
appear in this class in future specifications.
provides a mechanism to instantiate platform dependent objects in a
platform independent manner. The
class and the JspEngineInfo class are the
only implementation dependent classes that can be created from the factory.
Typically at initialization time, a JSP container will call the static
method in order to register it's own factory implementation. JSP
page implementation classes will use the
method in order to
obtain this factory and use it to construct
instances in order to process client
JspFactory objects are not intended to be used by JSP page authors.
The classes in the javax.servlet.jsp.tagext package are related to the Tag Extension
mechanism. They are described in detail in Chapter 5. In this section we will just briefly
review and group them.
A brief description of the classes follows. Classes whose name ends in Info are translation
time classes. Instances that are initialized from the Tag Library Descriptor are in bold italics:
Encapsulates the evaluation of a tag body.
The interface of a tag handler for an action that does not want to manipulate its body.
The interface of a tag handler for an action that wants to manipulate its body.
