Hibernate version: 2.1.4

Is there any way to add validation to the automatically created java classes based on the type and length fields? Currently the problem is that the values persisted to the database are being truncated to 2 characters but the cached objects are not truncated.

If there is not a way to automatically create this validation, where is this generally added?

This is in relation to the xml code snippit from the hbm.xml file:

- <property name="countryOfIssue" column="country_of_issue" type="string" length="2" not-null="false" unique="false" update="true" insert="true">
<meta attribute="use-in-tostring" inherit="true">true</meta>
</property>
