I doubt that. The build box might have a different ${catalina.home},
or no Tomcat at all.

I searched the spec on "macro", and "$" and found nothing that
indicated that it was required by the spec. However,

	SRV.1.5 Relationship to Java 2 Platform, Enterprise Edition

	The Java Servlet API v.2.4 is a required API of the Java 2
	Platform, Enterprise Edition, v.1.41. Servlet containers and
	servlets deployed into them must meet additional requirements,
	described in the J2EE specification, for executing in a J2EE
	environment.

    (Java(tm) Servlet Specification Version 2.4P)

I have not checked the J2EE spec.

I can ask my client, but they're in a product release crunch, so I
shouldn't right now.
