The MessageDrivenContext interface provides access to the runtime message-driven context that the container provides for a message-driven bean instance. The SessionBean interface defines methods that the EJB container uses to notify a session bean instance of the instance's life cycle events. The SessionContext interface provides access to the runtime session context that the container provides for a session bean instance. The SessionSynchronization interface allows a stateful session bean instance to be notified by its container of transaction boundaries.
The TimedObject interface contains a callback method that is used to deliver timer expiration notifications. The TimerHandle interface allows the bean provider to obtain a serializable timer handle that may be persisted. The TimerService interface provides enterprise bean components with access to the container-provided Timer Service. Wraps the result of an asynchronous method call as a Future object, preserving compatability with the business interface signature.
TimerConfig is used to specify additional timer configuration settings during timer creation. Used to specify the value of the ConcurrencyManagement annotation for a singleton session bean. The enum TransactionAttributeType is used with the TransactionAttribute annotation to specify whether the methods of a session bean or message driven bean are called with a valid transaction context. The enum TransactionManagementType is used with the TransactionManagement annotation to specify whether container-managed or bean-managed transaction management is used.
An AccessLocalException is thrown to indicate that the caller does not have permission to call the method. A ConcurrentAccessException indicates that the client has attempted an invocation on a stateful session bean or singleton bean while another invocation is in progress and such concurrent access is not allowed.
This exception indicates that an attempt to concurrently access a stateful session or singleton bean method resulted in a timeout. The CreateException exception must be included in the throws clauses of all create methods defined in an enterprise bean's home or local home interface. The EJBException is thrown to report that the invoked business method or callback method could not be completed because of an unexpected error e.
This exception indicates that a request carried a null transaction context, but the target object requires an active transaction. This exception is thrown to a remote client to indicate that the transaction associated with processing of the request has been rolled back, or marked to roll back. The FinderException exception must be included in the throws clause of every finder method of an entity bean's home or local home interface. This exception indicates that an attempt was made to perform an illegal loopback invocation.
This exception indicates that a calendar-based timer will not result in any more timeouts. A NoSuchEJBException is thrown if an attempt is made to invoke a business method on a stateful session or singleton object that no longer exists. The NoSuchEntityException exception is thrown by an entity bean instance to its container to report that the invoked business method or callback method could not be completed because of the underlying entity was removed from the database.
SessionContext; import java. In a terminal window, go to this directory:. Creates the bean's deployment descriptor. Introduction dialog box. Read the explanatory text for an overview of the wizard's features. In the combo box below this button, select ConverterApp. If the target directory is many levels down in the tree, you can simplify the tree view by entering all or part of the directory's path name in the Starting Directory field.
In the Available Files tree select these classes: Converter. You can also drag and drop these class files to the Contents text area. Under Bean Type, select the Stateless Session. In the Enterprise Bean Class combo box, select converter. In the Remote Home Interface combo box, select converter.
In the Remote Interface combo box, select converter. If you are deploying to GlassFish 3. The application client no longer needs to be deployed and run as part of an enterprise application. The class library that contains the remote interface now needs to be added to the classpath of the project to enable the application client to reference the EJB.
The class library project is open, so you can use the Call Enterprise Bean dialog to help you generate the code to call the EJB. If the class library project is not open, you can add the class library to the project in the Projects window by right-clicking the Libraries node and locating the JAR of the EJBRemoteInterface project.
The dialog automatically selects Remote as the interface type. Modify the main method to retrieve the String of the getResult method via the MySessionRemote interface. Save your changes. Alternatively, you can expand source package and right-click the Main. You can see the message from the application client in the Output window. Send Us Your Feedback.
