Getting Hostname IDP is running on

[Ramon Pfeiffer]

Hi Chris,

I faced the same problem, I resolved it using java.net.InetAddress as
you already suggested, by injecting it as a custom object into the views:

global.xml:
    <util:map id="shibboleth.CustomViewContext">
        <entry key="inetAddress">
            <bean class="java.net.InetAddress" />
        </entry>
    </util:map>

You can then access the inetAddress in your views via the $custom object:

footer.vm:
	$custom.get('inetAddress').getLocalHost().getHostAddress()

I don't know if injecting it as a custom object is necessary, but it
worked for me.

HTH,
Ramon
