This is true, and in general, Paul's suggestion below is the right way to go.

Still, it's interesting to note out that Struts 
(or more accurately, commons-beanutils) does 
support one special case where you can pass a 
parameter, the MappedProperty.  This is a 
property which requires a String parameter in the 
accessor: theoretically a key to a map.  You can 
subvert this to have an accessor which does 
something else with the String, such as use it 
for a date format.

I did this for a Struts 1.0 project before the 
JSTL was released and when the Struts bean tags 
also hadn't yet added any formatting control.
