Which of the following snippets of the deployment descriptor can be used to return the value "mySecret" when the following API is called: getServletConfig ().getInitParameter ("sharedSecret")?

The getServletConfig () API returns a ServletConfig class. When the Container initializes a servlet, the container
creates a unique ServletConfig for the servlet. In fact, each servlet in a web app has its own ServletConfig. The
container retrieves the servlet initialization parameters from the Deployment Descriptor, and makes them available
as part of the ServletConfig. Servlet init parameters are similar to context init parameters, except servlet
parameters are only available to a particular servlet while context parameters are available to the entire web
application.
To configure servlet init parameters that are accessible from the ServletConfig, one needs to use the
element. The element is used to configure servlet init parameters that are specific
for particular servlet, and hence, should be contained within the element.
Hence, the answer is:

.....

MyServlet</servlet-name>
MyServlet</servlet-class>

sharedSecret mySecret
.....
