public interface EJBHome extends java.rmi.Remote
The EJBHome interface must be extended by all enterprise beans' remote home interfaces. An enterprise bean's remote home interface defines the methods that allow a remote client to create, find, and remove EJB objects.The remote home 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 home interface.
- Since:
- EJB 1.0
