Using Request Dispatcher, you can send the values and
forward to another page.
ServletContext.getRequestDispatcher();
reqDispatcher.forward(req,res)
Forwards a request from a servlet to another resource
(servlet, JSP file, or HTML file) on the server.
reqDispatcher.include(req,res)
Includes the content of a resource (servlet, JSP page, HTML
file) in the response.

Answer / debojit
First of all u have to set the value by setAttribute()
method such as:
request.setAttribute("variableName",object);
Then u have to forward that request to other servlet by
using that procedure,
ServletContext con=request.getServletContext();
RequestDispatcher rd=con.getRequestDispatcher("/servlet");
rd.forward(request,response);
U can get that information from that servlet by using the
method::
getAttribute("variableName");

We can pass the data from one servlet to another using
RequestDispatcher object.
1.RequestDispatcher rd=getServletContext.getNamedDispatcher
("...");
rd.forward(request,response);
... means use the name of the url-patterns you have
specified for the servlet in web.xml.
