I want to make an servlet that will use my web service, (String flag(string country)), receives a name of a country and returns the URL with the image of the country! The function is working good, it's receiver properly and is returning the right data:
Returns the string -> "http://www.oorsprong.org/WebSamples.CountryInfo/Images/Poland.jpg", I would like to redirect my browser to this URL.
For that, it should be sent with JSP, XML code, I tried an example from this tutorial http://www.tutorialspoint.com/jsp/jsp_page_redirect.htm,
<%@ page import="java.io.*,java.util.*" %>
<html>
<head>
<title>Page Redirection</title>
</head>
<body>
<center>
<h1>Page Redirection</h1>
</center>
<%
// New location to be redirected
String site = new String("http://www.photofuntoos.com");
response.setStatus(response.SC_MOVED_TEMPORARILY);
response.setHeader("Location", site);
%>
</body>
</html>
and it works when I put directly in my JSP input code.
But on the JSP for the output i can't redirect the flag's URL, because the code doesn't recognize it as something to execute, and it shows as a result.
And it's just prints the lines I want to be executed.
And here is the code I used:
