Hi Richard,
Thanks a lot for the reply.I did exactly as u suggested.But even then
I am unable to get the information.
My web.xml file:
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<servlet>
<servlet-name>
Test
</servlet-name>
<servlet-class>
InitTest
</servlet-class>
<init-param>
<param-name>
host
</param-name>
<param-value>
basie.ittc.ku.edu
</param-value>
</init-param>
</servlet>
</web-app>
My Servlet:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class InitTest extends HttpServlet {
public String host;
public String name;
public void init(ServletConfig config) throws ServletException {
super.init(config);
// host = getInitParameter("host");
host = config.getInitParameter("host");
name = getServletConfig().getServletName();
}
public void doGet(HttpServletRequest req, HttpServletResponse resp)
throws ServletException,IOException {
resp.setContentType("text/html");
PrintWriter out = resp.getWriter();
out.println("<html><head><title>Hello</title></head>");
out.println("<body>this is string: "+host+" </body>");
out.println("</html>");
}
}
My Servlet output:
this is string: null
