Special Edition Using Enterprise JavaBeans™ 2.0

Declaring the Component Interface

As with entity beans, a client’s view of a session bean is defined by the bean’s component interface. Remember that a remote interface must always be declared to extend EJBObject and a local interface must extend EJBLocalObject. As illustrated previously with entity beans, the remote and local interfaces are where you define the business methods you want to expose to clients of your beans. Again, these methods must be declared such that

• No method name starts with ejb

• All methods are declared as public

• No method is declared as static or final

• All remote interface methods include java.rmi.RemoteException in their throws clauses

• All remote interface method arguments and return types must be legal RMI-IIOP types
