2 ways of getting a RequestDispatcher

[Rajiv Chelsea]

What is the difference between the getRequestDispatcher(String path) method of javax.servlet.ServletRequest interface and javax.servlet.ServletContext interface?

[Abimaran Kugathasan]

If I correct, ServletContext's getRequestDispatcher(String path) method has the absolute path/url as argument!

[Rajiv Chelsea]

That's correct

Are there any advantages we get by getting requestDispatcher from
ServletContext?

[Sudipta Laha]

There is a method getContext(string) in servletContext which can be used to get the foreign context. so we can use the method getRequestDispatcher to get the RequestDispatcher for resources in foreign context. But when we use the request.gerRequestDiapatcher method we get the RequestDispatcher of the current context only.
So the servletContext requestDispatcher may be helpful in some scenarios.
