Well, JAVA_HOME is expected to already point to the correct JDK location.
And you would simply invoke the appropriate wrapper for each program
(e.g., invoke "java" to find "java.exe", "jar" to find "jar.exe", etc).
The wrappers will "help" those JDK programs understand Cygwin paths, etc.
Their intent was to help non-Cygwin-aware Unix scripts that invoke java
and other JDK executables.

One of the future work items in the wrappers is the logic (which would
most likely go into a /etc/profile.d script) to find some Java
installation automatically and set JAVA_HOME if it's not already set.
But this is obviously not done yet.

I'm not very familiar with the Tomcat build procedure, but, IIRC, my
wrappers will not be very helpful for Ant, as its build scripts understand
the JAVA_HOME setting, are Cygwin-aware, and do the appropriate path
conversion themselves (so the wrappers never get invoked -- Ant invokes
java.exe directly).
