ServletContext initialization parameters

[Naresh Chaurasia]

Hi,
Question 2 of Mock exam chapter 5 says that servletcontext initialization parameters should be used for data that rarely changes. I have doubt whether the statement should be rarely changes or does not change.Can someone give me an instance where this parameter changes.

thnx in advance.

Chaurasia,

The Context init-param can only be changed manually by updating the web.xml, hence its for data that "rarely changes." It depends on the parameters being added to the web.xml, one example is the configuration file names or path changes that need to be loaded when the container loads. These file names or path don't change that often, but when they do, you need to update the web.xml.
