OK, thanks! You know, you could just take what you
have written right here, and place that in the documentation.
Just a simple quick description of what one has to
do, all in one place, is enough for most people.
thanks again,

correct.
It's very simple:
1. you need a dedicated column of type INTEGER or TIMESTAMP
2. you need a (possibly private) attribute in your java class
corresponding to the column.
3. in repository.xml you need a field-descriptor for this attribute.
this field-descriptor must specify locking="true"
