No, the map literal syntax is new to 1.5. however, there are ugly,
dangerous hacks like this:
#set( $object = 0 )
#set( $personnelRecord =
$object.class.forName('java.util.HashMap').newInstance() )
but i can't in good conscience recommend that. i think you should
just create a tool that returns new HashMaps on demand and put the
tool in the context.
public class MapMaker {
public Map makeMap() {
return new HashMap();
}
}
context.put("mapMaker", new MapMaker());
#set( $personnelRecord = $mapMaker.makeMap() )
#set( $foo = $mapMaker.put('name', "...") )
and so on...

Thank you Nathan.
I do not need a specific object type, but also am not using Velocity
1.5. Is there an equivalent syntax available in 1.4 to allow me to
create the map?
