Struts/Hibernate and date troubles

Dear all,

I'm getting squeezed between Struts and Hibernate when I use Date type
for a record.
My setup is the simplest possible.
This is my mappings file
<?xml version='1.0' encoding='utf-8'?>

<!DOCTYPE hibernate-mapping PUBLIC
"-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

<hibernate-mapping>
<class name="com.ft.ht.DictatorForm" table="DICTATOR">

<meta attribute="class-description">
testing Struts with Hibernate
</meta>

<id name="id" type="int" column="DICTATOR_ID">
<meta attribute="scope-set">protected</meta>
<generator class="native"/>
</id>

<property name="added" column="ADDED" type="timestamp"/>
<property name="firstName" type="java.lang.String" not-null="true"
column="FIRST_NAME"/>
<property name="lastName" type="java.lang.String" not-null="true"
column="LAST_NAME"/>
<property name="birthDate" column="BIRTH_DATE" type="timestamp"/>
<property name="offsprings" type="short" column="OFFSPRINGS"/>

</class>
</hibernate-mapping>

The timestamp type gets translated into java.util.Data in the POJO and
in datetime in the
database schema. I heve MySQL as my DB.

I use the above mapping to generate a POJO which then I modify to
extend ActionForm.
I have to modify then all the setters to accept String (instead of
java.util.Date), that's to make
Struts happy.

The trouble is that Hibernate is unhappy with the setter. When I try
to commit something with Date I get :

org.hibernate.PropertyAccessException: IllegalArgumentException
occurred while calling setter of com.ft.ht.DictatorForm.birthDate

If the setters are let to accept Date then Strings shouts at me...

So far I was experimenting only with Strings and Dates. If I go only
with String everything is working...

What am I to do then? Can somebody point me to a complete example
which uses Hibernate with Struts and
commits multiple types of data to the Database (MySQL)

Cheers,
Thomas

I have not a master's degree on Hibernate, but what strikes to my eye is
that you declare type="java.lang.String" to strings and type="timestamp" to
dates. If java.lang.String is correct, then maybe date-columns want a java-
classdef too, no?

Dunno if it has to be java.util.Date or java.sql.Date or
java.sql.Timestamp...
