Hi All,

I have a table [Trading Partners]



Is the following TradingPartner.hbm.xml is correct??



Please correct me, if i somthing is missing..

Also is it necessary to have <id> element in .hbm.xml file..

<id name="id" column="uid" type="long">
<generator class="hilo"/>
</id>


I may not need a column, which is auto generated..

If its there, how can i give my own value, [unique key which i would want to generate/set] & not hibernate's <generator> node.

All the required values for each of the column will be set in code/application..

Any help would be highly appreciated..
Thanks in Advance.

composite-id replaces id
but I would recommend to use an generic primary key instead of a composite id beeing composed of so many columns. Do not forget that each entity having a relation to your mapping must have each column in the mapping configuration.

You can read more about generators for primary keys in the Hibernate Reference.

It is sorta covered in the JavaRanch Style Guide.
