It'd only be a few line custom Taglib to write a tag that does a HashMap key
lookup. It's not possible with <bean:write> in its current form, although
I believe the Commons BeanUtils code has recently been updated to include
this kind of lookup, but its not necessary in order to write a simple custom
tag.
