Any public methods should just work.

Pray tell -- what's the error? :-)
I just tried it out...works for me.
String template = "$MAP.containsKey('FOO') $MAP.containsKey('BAR')";
// Also works with $MAP.containsKey("FOO")
VelocityContext context = new VelocityContext();
HashMap mymap = new HashMap();
mymap.put("FOO", "BAR");
context.put("MAP",mymap);
StringWriter w = new StringWriter();
Velocity.evaluate(context, w, "myTemplate", template);
Cheers,
Tim
