In my project we use the sendRedirect method which is nt working in our project i would like to know whether there is any other method which can be used instead of sendRedirect().
you didn't specify that in what context you want to use sendRedirect() method and where you are facing problem using it in your programming code.
According to my assumption if you want to transfer the control of resources within the server you can use methods of RequestDispatcher. I hope this may helpful for you.
For detail tutorial of RequestDispatcher you can visit the link Java Servlet :RequestDispatcher Interface
