Answer 1

您应该先检查是否可以通过该路由访问jsp， http://host:port/context_root/Hello.jsp可以在Web浏览器中工作？

Answer 2

use

request.getRequestDispatcher("Hello.jsp").forward(request, response);

and see if it works

Answer 3

first you have to define the RequestDispatcher method,

Like this:

RequestDispatcher rd=request.getRequestDispatcher("filename.jsp");
rd.forward(request,response);

Make sure your jsp file is in the same directory of the servlet directory.
