Hi,

I am doing a prototype with spring and i wrote a ApplicationContextUtil.java tat loads the context file of my project. So i got few questions on that,


1. I was asked to use Introspecter.flushCaches on context destroy. My question is what is this Introspector and where we need to use it. I checked some sites and i didnt get a proper explanation.

2. servletContextEvent.getServletContext().setAttribute("org.springframework.web.context.WebApplicationContext.ROOT",applicationContext);

wat is the purpose of the above attribute and wht it does?

Thanx for ur reply objects,

I referred to the same site for Introspector - i could make out that it is an API which IDE (java based) would make use of to list the properties and methods in a bean. But my question is how it is related to the loading of Spring context file in my application?. I would like to know the reason for using it.

Similarly y is this Context root used, what would happen if i dont give it..

Spring is all about beans, and the Introspector is part of the standard Java beans api that comes with java. The flushCaches() method is used to clear all the bean info stored by that package. Part of the cleanup process.
