This section describes the various components that you must configure in order to use a relational one-to-many mapping.

For information on how to configure EclipseLink mappings options common to two or more mapping types, see Configuring a Mapping.

For information on how to create EclipseLink mappings, see Creating a Mapping.

This table lists the configurable options for a relational one-to-many mapping.

Configurable Options for Relational One-to-Many Mapping

Option	Workbench	Java
Configuring Reference Descriptor
Configuring a Type Conversion Converter
Configuring Read-Only Mappings
Configuring Mapping Comments
Configuring Batch Reading
Configuring Mapping Comments
Configuring Bidirectional Relationship
Configuring Container Policy
Configuring Mapping Comments
Configuring Joining at the Mapping Level
Configuring Query Key Order

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);
}
