In other words, if you allow untrusted parties to create and run
templates on your system, you need to read

What Velocity template code can I use to get a list of keys and iterate
over that list, getting the value corresponding to each key? Here is
what I've tried so far:
Before calling Velocity, I place the list of keys plus each key/value
pair in the context. For example:
--
String [] letters
Try using a Map interface object like HashMap or TreeMap.
HashMapString, String hm=new HashMapString, String();
hm.put(a,apple);
hm.put(b,blueberry);
ctx.put(map,hm);
Then in Velocity:
#foreach ($key in $map.keySet())
$key $map.get($key)
#end

Thank you, that worked beautifully.
I remember reading somewhere, though, that allowing a template to call
arbitrary methods (that is, methods other than bean-like getters) on
classes was dangerous, and that support for it might be eliminated in a
future version. Is this true, and
Allowing a template to call arbitrary methods is only dangerous if you
are allowing 3rd-parties to create templates and do not have your java
security policies properly configured for that.
Calling arbitrary methods does also allow for bad design if you allow
methods which change model state to
