I'm using hibernate-tools for ant.

I would like to wrap the keys for every table in an Id object, even the simple single field key table's.

Currently, Id objects only get created for tables with multiple fields as part of the key (composite-id).

I partially answered my own question. To clarify, I am generating the java from the hbm.xml files.

I also generate the hbm.xml files.

I can change the id.hbm.ftl file to generate a composite-id instead of an id attribute for every field.

But, is there another option that wouldn't require template changes.

currently we just look at the number of columns in the pk.

we could ask the revengstrategy instead and let it drive the decision; allowing you to control it. e.g. a hasCompositeIdentifier(TableIdentifier, ...)

put it in jira. patches welcome.
