Package javax.servlet.jsp
Interface JspPage
-
- All Superinterfaces:
Servlet
- All Known Subinterfaces:
HttpJspPage
public interface JspPage extends Servlet
This is the interface that a JSP processor-generated class must satisfy.The interface defines a protocol with 3 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.
A class implementing this interface is responsible for invoking the above methods at the apropriate time based on the corresponding Servlet-based method invocations.
The jspInit(0 and jspDestroy() methods can be defined by a JSP author, but the _jspService() method is defined authomatically by the JSP processor based on the contents of the JSP page.
