Developing a session bean to have a No-Interface Local view

You can specify that a session bean have a No-Interface view.

About this task

A session bean has a No-Interface Local view when:

The bean does not expose any other client views (Local, Remote, 2.x Remote Home, 2.x Local Home, Web Service) and its implements clause is empty.
The bean exposes at least one other client view. The bean designates that it exposes a no-interface view with the @LocalBean annotation on the bean class or in the deployment descriptor.

You can also declare metadata for a session bean with No-Interface Local view in the deployment descriptor rather than using annotations.

The following steps contain code snippets that demonstrate the code to use for a No-Interface view.

Procedure

```
@Stateless

@Stateless
@LocalBean
@Remote( Cart.class )
