How to embed server hostname in JSP page on clustered Tomcat
I have a cluster of (currently) two Tomcat 5.5.17 instances. I want to put a
hidden field on the pages which tells me which machine I am currently
connected to. Reading the spec it appeared that using:-
<input type="hidden" name="host" value="${pageContext.request.serverName}" />
should work, but it would appear that all this does is take the server portion
of the URL.
Anyone know how to do this (short of writing some Java code that is, I would
rather use simple JSP and JSTL).
David

You could try ${pageContext.request.localName}, but if you are using the
AJP/1.3 Connector, that won't work either (it will be the ServerName of the
Apache machine).

Not sure if you got a response to this, but this has worked for myself.
<%@ page import="java.net.InetAddress" %>
<%
InetAddress ia = InetAddress.getLocalHost();
out.println("<!-- hostname " + ia.getHostName() + " -->");
%>
