You can either forward it or redirect it.
To forward, you can use RequestDispatcher
RequestDispatcher rd = request.getRequestDispatcher("abc.jsp");
rd.forward(request, response);
To redirect,
response.sendRedirect("abc.jsp");
FYI , Difference between the two,
In Forwarding, the same request object is forwarded to the next resource (Servlet or JSP) and in Redirecting client (browser) is asked to send a new request to the server for the next resource (servlet or JSP).

Using RequestDispatcher
programatically...
public class Demo extends HttpServlet{
public void doGet(HttpServletRequest req , HttpServletRespaonse res)
throws ServletException, IOException {
res.setContentType(text/html);
PrintWritter pr = res.getWriter();
pr.println("i am in servlet");
RequestDispatcher rd = req.getRequestDispatcher("abc.jsp");
rd.forward();
}
}
abc.jsp
<body>
<i am abc in abc.jsp>
</body>
