`Servlet`

`ServletContext.getServlet(String name)`
Deprecated. As of Java Servlet API 2.1, with no direct replacement.

`Enumeration<Servlet>`

`ServletContext.getServlets()`
Deprecated. As of Java Servlet API 2.0, with no replacement.

This method was originally defined to return an `Enumeration` of all the servlets known to this servlet context. In this version, this method always returns an empty enumeration and remains only to preserve binary compatibility. This method will be permanently removed in a future version of the Java Servlet API.

Methods in javax.servlet with parameters of type Servlet
`ServletRegistration.Dynamic` `ServletContext.addServlet(String servletName, Servlet servlet)` Registers the given servlet instance with this ServletContext under the given `servletName`.
