How to Include a JSP Fragment into a JSP Page while forwading from Servlet?
Question
First, Please suggest me if my question heading is not correct.
Moving on to question: Say I am having below components:
search.jsp - A JSP Page with a Form to Submit Data
Search.java - A controller Servlet having both get() and post() defined separately so that it can acts as a dispatcher for path /search.jsp
searchResults.jspf - A Fragment with some JSTL code to show up the Search Results
What I want here is for every POST request the controller servlet has to do its calculation, set results as Request Attributes and than - forward the request to the view search.jsp that should include the Fragment after its own codes .
So that, I can have a View Defined in such a way as:
search.jsp
+
searchResults.jspf
on a single page.
Problem is, I can either do Forward or Include with the dispatcher as I don't know how can i Include a fragment while forwarding to a JSP into it.
Let me know if I need to post some code if necessary, or need any corrections.

In your search.jsp embed your searchResult.jsp using jsp:include:
<jsp:include page="searchResult.jsp"></jsp:include>
Exemple: 1. The servlet:
@WebServlet(name = "Servlet", urlPatterns = "/myForwardTest")
public class Servlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.getRequestDispatcher("search.jsp").forward(request, response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
}
search.jsp:
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <html> <head> <title>In search resust</title> </head> <body> Search.jsp embed searchResult.jsp <jsp:include page="searchResult.jsp" /> </body> </html>searchResult.jsp
<%@ page contentType="text/html;charset=UTF-8" language="java" %> <body> in searchResult </body> </html>

You can include your jspf in your jsp like below:
<%@include file="searchResult.jspf" %>
you can set a statement to execute a certain section only if a particular test evaluates to true .
Ex:
if(.....==true){
<%@include file="searchResult.jspf" %>
}else{
<%@include file="someOther.jspf" %>
}
