Why use ServletContext.setAttribute()?
servlets, setattribute
Solution
The `servletContext.setAttribute()` is dynamic which can be set and reset during runtime.
Where as `init-parameter` specified in `web.xml` is static which will not change during the lifetime of application.
Example:
- The database properties like database name configuration propety. It will be mostly configured as context `init-param`
- And if you want to set property value which derives based on runtime changes, like "last user logged in" or "number of failures" should be context attributes.
Problem
Why would we set ServletContext parameters using the `setAttribute()` method, as we can accomplish the same thing by setting parameters in `web.xml` and fetching them using `getInitParameter()`?
