Name
JspPage
Synopsis
The JspPage
interface must be implemented by the
generated JSP page implementation classes. The interface defines a
protocol with three methods; only two of them, jspInit(
)
and jspDestroy( )
, are part of this
interface as the signature of the third method, _jspService(
)
, depends on the specific protocol used and cannot be
expressed in a generic way in Java. See also
HttpJspPage
.
The JspPage
interface represents the basic,
protocol-independent contract between the container and a JSP page
implementation object. A protocol-dependent subinterface, such as
HttpJspPage
, must be implemented by the class
generated from a JSP page.
The jspInit( )
and jspDestroy(
)
methods can be defined by a JSP page author.

Methods
-
public void jspDestroy( )
This method is invoked when the JSP page implementation instance is about to be destroyed. It can be used to perform clean-up, such as saving the state kept in instance variables to permanent storage.
-
public void jspInit( )
This method is invoked when the JSP page implementation instance is initialized. It can be used to perform tasks such as restoring the state kept in instance variables from permanent storage.
