Servlet context is used for the persistency of the data for the servlets within the same web application or within the same servlet engine.

So a particular data is common for all servlets sharing the same web application.

Whereas the servlet config is used to use a particular data for each servlet.

Other servlet in the web application cannot access the data obtained by servlet config of other user.  Servlet config is used to access the data for itself. Other servlet cant access others servlet config data.
