/**
* Declares the local business interface(s) for a session bean.
*
* The Local annotation is applied to the session bean class or local
* business interface to designate a local interface of the bean.
*
* When used on the bean class, declares the local business interface(s)
* for a session bean. When used on an interface, designates that interface
* as a local business interface. In this case, no value element
* should be provided.
*
* The Local annotation applies only to session beans and
* their interfaces.
*
* Use of the Local annotation is required when the bean class
* exposes one or more local business interface and any of the following is true:
*
* - the bean class does not implement its business interfaces
*
- the bean exposes a no-interface view
*
- the bean class implements more than one interface and at least one of the interfaces
* is explicitly designated as a business interface by using the
Local
* or Remote annotation on the interface, or in the deployment descriptor
*
*
* The following interfaces are excluded when determining whether the bean class
* has business interfaces: java.io.Serializable;
* java.io.Externalizable; any of the interfaces defined in jakarta.ejb.
