RequestDispatcher

[Apan Raj]

Can any ony let me know the different ways of getting RequestDispatcher object in a servlet, and how actually they differ.

[Ramakrishnan thiyagarajan]

hi,
Request dispatcher is a interface.actually RequestDispatcher means to dispatch the incoming Http request to some other servlet or jsp page. this is a concept.but u can obtain it two ways.
throug ServletContext,HttpServletResponse.

Hi !
Ramakrishna is right. The methods used are:
You use either the getRequestDispatcher(relative path of resource)
or getRequestDispatcher(absolute path of resource)
or getnamedDispatcher(name of the resource)(Check the method name)

As per the API, there is no much difference between the methods in ServletContext and ServletRequest ( Ramakrishna, its not HttpServletResponse ), except that
the method in ServletContext accept only relative path where as the other method also accept absolute path.
