This example shows how to create a one-to-many mapping and add it to a descriptor using Java code.

One-to-Many Mapping

public void customize(ClassDescriptor descriptor) { 
    OneToManyMapping mapping = new OneToManyMapping();  

    // configure mapping
    ... 

    // add mapping to descriptor
    descriptor.addMapping(mapping);
}
