Access Java Library in IDP v5

[Ruderman, Kevin]

Hi Folks,

I global.xml I have:
    <util:map id="shibboleth.CustomViewContext">
      <entry key="hostname" value="#{systemEnvironment['HOSTNAME']}"/>
    </util:map>

In tomcat bin/setenv.sh I add:
# Used in global.xml and then login.vm as a breadcrumb comment
HOSTNAME=`/usr/bin/hostname 2>/dev/null`
export HOSTNAME

Then in login.vm I have:
<!-- Hostname ID: $custom['hostname'] -->

For me it's just there so I can tell the backend. I don't display it to users but I could.

Regards, Kevin

You probably were getting away with something improper, if you want a class object, that would be class="T(classname)".

I think you can also get hold of classes indirectly in Velocity with a trick like $object.getClass().forName("name of other class") because you can call static methods on actual objects.

A custom property set differently per host probably.
