ServletContext object

ServletContext object is created using the web container at time of deploying the project. This object can be used to get configuration information from web.xml file. There can only be one ServletContext object per web application. If there is any need to provide the information that is shared to many servlet it is better to provide using the web.xml file with the <context-param> element.

By this way it is easy to maintain all the information that is shared to all the servlet. It is good to make available the information for the servlet. These changes are provided in web.xml file. In case of change in information, there is no need to modify the servlet.
