Interface EJBLocalObject

public interface EJBLocalObject
The EJBLocalObject interface must be extended by all enterprise beans' local interfaces. An enterprise bean's local interface provides the local client view of an EJB object. An enterprise bean's local interface defines the business methods callable by local clients.

The enterprise bean's local interface is defined by the enterprise bean provider and implemented by the enterprise bean container.

Enterprise beans written to the EJB 3.0 and later APIs do not require a local interface that extends the EJBLocalObject interface. A local business interface can be used instead.

Since:
EJB 2.0

      Test if a given EJB local object is identical to the invoked EJB local object.
      Parameters:
      obj - An object to test for identity with the invoked object.
      Returns:
