Setting idp.home

[Baron Fujimoto]

The Apache Tomcat 8 wiki page suggests setting idp.home as a context parameter
in edit-webapp/web.xml (and rebuilding) should work. 
<https://wiki.shibboleth.net/confluence/display/IDP30/ApacheTomcat8>

However when I try this, it results in the following error:

[ERROR] : org.springframework.web.context.ContextLoader: Context initialization failed
net.shibboleth.utilities.java.support.logic.ConstraintViolationException: Unable to find '/conf/idp.properties' at well known locations

I've verified that the resulting idp.war file contains the web.xml
with that context parameter set. The web.xml sits at the top level
of the unpacked war file, if that makes any difference. E.g.:

css/  images/  index.jsp  js/  META-INF/  WEB-INF/  web.xml  x509-prompt.jsp

It seems like I must define "-Didp.home=<location>" in CATALINA_OPTS.

Am I missing something?

Tomcat 8.0.35
IdP 3.2.1
