Pass information to another servlet

You set attributes on your request object and then forward the request object to the other servlet/jsp.

For a simple string

request.setAttribute("foo", "Real's HowTo");

A parameter received by the first servlet to the second one

String requestVar = request.getParameter("sitename");
request.setAttribute("foo", requestVar);

A Bean

MyBean myBean = new MyBean();
myBean.setFooProperty("Real's HowTo");
request.setAttribute("foo", myBean);

Then you forward the request

RequestDispatcher dispatch = request.getRequestDispatcher("next.jsp");
dispatch.forward(request, response);
