What JSP lifecycle methods can I override?

You cannot override the _jspService() method within a JSP page. You can however, override the jspInit() and jspDestroy() methods within a JSP page. jspInit() can be useful for allocating resources like database connections, network connections, and so forth for the JSP page. It is good programming practice to free any allocated resources within jspDestroy().The jspInit() and jspDestroy() methods are each executed just once during the lifecycle of a JSP page and are typically declared as JSP declarations:<%!public void jspInit() {. . .}%><%!public void jspDestroy() {. . .}%>

Any code written in jsp with in <%... %> tag is placed by the container into jspService() method. Anyhow we can override jspInit() and jspDestry() using <!%...%>. but we cannot override jspService() method in jsp.

The overriding of JSPINIT method is useful as we are getting the intialization for connections and not the destroy....As after execution of JSP it automatically dies
