You have to cast the result:
String[] mySelect = (String[]) form.get("mySelect");
Because BeanUtils and PropertyUtils know how to deal with DynaBeans, you
can also use them, for example:
String[] mySelect = PropertyUtils.getProperty(form, "mySelect");
This has the advantage that you could change your mind later and create a
real ActionForm subclass if you wanted to, but it will also run a little
slower.
