What is your client side code (JSP)?
In OGNL expression, a value assignment is something like:
aMap[aKey] = aValue
So, you need create HTML code like:
input name=aMap[aKey] value=aValue /

But struts-2 breaks this scheme.

(A)Declare the input data field in your action as a String, instead of

So, the String field can hold anything input from client side.
But this will be inconvenience to use, because you have to convert the
string value
to the date or integer value by yourself,
I think lazy initialization is a simple choice, because it is not
dependent on the J2EE container, this make your code easy to test.

For output case, the s:date tag can let you choose the format to use.
