Hi all.
Is there a way to set the generator class value in the code rather than in the *.hbm.xml file?

Currently I am doing something like :
<id name="id" type="integer" column="CAT_ID">
<generator class="identity">
</id>

Is there a way do something like:
1. <id name="id" type="integer" column="CAT_ID"/>
2. Set the generator class in Java code

Hibernate version: 3.0 rc1

Thanks

I did something like this:

Code:

Configuration cfg = new Configuration();
Iterator mappings = cfg.getClassMappings();

while (mappings.hasNext) {
    RootClass rootClass = (RootClass)mappings.next();

    SimpleValue simpleValue = new SimpleValue(rootClass.getTable);
    System.out.println(simpleValue.getIdentifierGenerationStrategy());
}

I figured I could use this to set the generator class for id:

Code:

simpleValue.setIdentifierGenerationStrategy()

Output:
assigned

The problem is i have my hbm.xml set like this:

Code:

<id name="id" type="integer" column="CAT_ID" unsaved-value="0">
    <generator class="identity"/>
</id>

So, I was expecting the output as 'identity' and not 'assigned'.

Can anyone tell where I am going wrong?

I am using Hibernate 3.0rc1 with DB2 8.1.3 UDB

Thanks.
