wanhing commented on HBX-725:
-----------------------------

But this is not the documented behaviour. According to Hibernate documentation, hibernate timestamp is mapped to  java.sql.Timestamp, which has nano value. Millisec might be enough for most but not enough for some (including us), that's why Java has java.sql.Timestamp. Also if both hibernate date and timestamp map to java Date, then why bother to have hibernate "timestamp" type?

> When I use "timestamp" in the mapping definition file, the generated java class has "Date" instead. As a result I lost the granuity that I need. Example:
> ====================================================================
>   <class name="TaskDuration">
>     <meta attribute="class-description">
>       @jboss-net.xml-schema urn="tms:TaskDuration"
>     </meta>
>     <id name="id" column="TaskDurationId" type="long" >
>       <generator class="native"/>
>     </id>
>     <version name="version" />    
>         
>     <property name="datetime"   type="timestamp" not-null="true"/>
>     <property name="duration"   type="float"     not-null="true"/>
>  </class>
> =====================================================================
> The generated java class has:
> public class TaskDuration  implements java.io.Serializable {
>  ....
>      private Date datetime;
>     public void setDatetime(Date datetime) {
>         this.datetime = datetime;
>     }
>     public Date getDatetime() {
>         return this.datetime;
>     }
>  ...
> }
