  1. What is difference between ServletConfig and ServletContext?

    Some of the differences between ServletConfig and ServletContext are:

    • ServletConfig is a unique object per servlet whereas ServletContext is a unique object for complete application.
    • ServletConfig is used to provide init parameters to the servlet whereas ServletContext is used to provide application level init parameters that all other servlets can use.
    • We can’t set attributes in ServletConfig object whereas we can set attributes in ServletContext that other servlets can use in their implementation.
