1. In your table you need a dedicated column of type INTEGER or
TIMESTAMP . Say the column is typed as INTEGER and named
VERSION_MAINTAINED_BY_OJB .
2. You then need a (possibly private) attribute in your java class
corresponding to the column. Say the attribute is defined as:
private int versionMaintainedByOjb;
3. in repository.xml you need a field-descriptor for this attribute.
this field-descriptor must specify locking="true" The resulting
field-descriptor will look as follows:
<field-descriptor
name="versionMaintainedByOjb"
column="VERSION_MAINTAINED_BY_OJB"
jdbc-type="INTEGER"
locking="true"
/>
