What is ServletContext() and what is its use?
Answer Posted / shyam
if u want to use any data which is common for all use and
common to all servlet ,that data can be specified as context
parameters in the web.xml as follows.
<context-param>
<param-name>city</param-name>
<param-value>bangalore</param-value>
</context-param>
web container collects data from web.xml and stores that in
servlet context objects as context parameters.
As a developer,you can collect that data form context object
as follows.
String ci=context.getIntParameters("city").
All the servlets will have only one servlet context object
and can be shared with all servlets running in the container.
i.e: one web application will have one servletcontext object.
