Question { Infrasoft, 37414 }

we cant Override Jsp Service method?Why?

Answer

The content what we are written in the JSP will go into
_jspService()method because we are implicitly implemented
it.if we again try to override explicitly, the JSP compiler
given error as " THE METHOD IS ALREADY IMPLEMENTED AND CAN'T
OVERRIDE" but in case of other two methods we are not
implementing it in the jsp.therefore the jsp compiler will
allow we can override jspInit() and jspDestroy().

Any method which are not to be overridden by the end
user are typically written starting with an '_'.
