Handling relay response using Java

Created by Richard Moore, Modified on Wed, 12 Apr, 2023 at 12:02 PM by Richard Moore

The Relay Response sample code below shows how the merchant could respond upon receiving the transaction results from E-xact.  In this JSP example, the developer would change each merchant.com placeholder URL to the merchant's absolute URL equivalent.


<%@ page language="java" import="java.lang.*" %>
<!DOCTYPE html

 <h1>Merchant.com Online Store</h1>

 <h2><%=request.getParameter("x_response_reason_text")%></h2>

 <% if(request.getParameter("x_response_code") == '1') { %>
   <p>
     Your payment was processed successfully.
     Your order will be shipped in two business days.
     Here is your receipt.
   </p>
   <pre>
     <%=request.getParameter("exact_ctr")%>

   <% if(request.getParameter("exact_issname") != null) { %>
     <p>
       Issuer:     <%=request.getParameter("exact_issname")%><br/>
       Confirmation Number:     <%=request.getParameter("exact_issconf")%>
     </p>
   <% } %>

   <p>
     <% String track_url = "http://merchant.com/order_tracking/" + request.getParameter("x_invoice_num"); %>
     You can track it at <a href="<%= track_url%>"><%= track_url %></a>.
   </p>
 <% } %>

 <% if(request.getParameter("x_response_code") == '2') { %>
   <p>
     Your payment failed.
     Here is your receipt.
   </p>
   <pre>
     <%=request.getParameter("exact_ctr")%>
   </pre>
 <% } %>

 <% if(request.getParameter("x_response_code") == '3') { %>
   <p>
     An error occurred while processing your payment.
     Please try again later.
   </p>
 <% } %>

 <p>
   Return to <a href="http://merchant.com/home">home</a>.
