supposedly the mapping class looks at Key_xxx and Element_xxx inside
Class-conversion*.properties
This {@link ObjectTypeDeterminer} looks at the
<b>Class-conversion.properties</b> for entries that indicated what
* objects are contained within Maps and Collections. For Collections, such as
Lists, the element is specified using the
* pattern <b>Element_xxx</b>, where xxx is the field name of the collection
property in your action or object. For
* Maps, both the key and the value may be specified by using the pattern
<b>Key_xxx</b> and <b>Element_xxx</b>,
* respectively.
in your fuBar Class
fuBar-conversion.properties would look like
# syntax: <type> = <converterClassName>
java.lang.Double = com.acme.MyDouble
/**
* Determines the element class by looking for the value of @Element
annotation for the given
* class.
* If no annotation is found, the element class is determined by using the
generic parametrics.
*
* As fallback, it determines the key class by looking for the value of
Element_${property} in the properties
* file for the given class. Also looks for the deprecated
Collection_${property}
*
* @param parentClass the Class which contains as a property the Map or
Collection we are finding the key for.
* @param property the property of the Map or Collection for the given
parent class
* @see

String, Object)

as you can see there is no conversion to String in getClass below

of course any/all values passed thru HTTP GET are "passed as String" ...is this
what you're seeing with WireShark?
