JSP pages are high level extension of servlet and it enable the developers to embed java code in html pages. JSP files are finally compiled into a servlet by the JSP engine. Compiled servlet is used by the engine to serve the requests.
javax.servlet.jsp package defines two interfaces:
*
JSPPage
*
HttpJspPage
These interfaces defines the three methods for the compiled JSP page. These methods are:
* jspInit()
* jspDestroy()
* _jspService(HttpServletRequest request,HttpServletResponse response)
In the compiled JSP file these methods are present. Programmer can define jspInit() and jspDestroy() methods, but the _jspService(HttpServletRequest request,HttpServletResponse response) method is generated by the JSP engine.
