you can't.

You shouldn't need to anyway. JSP aren't meant to hold business logic, only display logic.
If you think you need to put any computation or data manipulation code in a JSP you need to instead rethink your application design.

You have got the best suggestion, Vara.

Why? Your jsp page may extends your own class and you can have your own
jspInit, jspDestroy

I am not discussing is it good or not, but technically it is possible and it is described in the spec.

correct, its technically possible.
You have to override _jspInit() in a <%!......%> (declarative tag).

You can declare your JSP page as a servlet in your web.xml file and provide intialization parameters just like you would any other servlet. Then, in your JSP page, you can access the implicit config object (a ServletConfig instance) to access the servlet-specific information related to your JSP page.

Is that what you were asking about?
