public class ApplicationException

extends java.lang.Exception

implements MessageCatalogException

The ApplicationException class is used to signal business logic exceptions to a caller. It is the base application exception class. According to the EJB 1.1 specification, an application exception is an exception defined in the throws clause of the enterprise bean home and remote interfaces, other than the RemoteException.

A bean provider is responsible for defining application exceptions in bean remote and home interfaces and is also responsible for throwing an appropriate application exception from a bean method to report a business logic exception to the client. If necessary, the bean provider should subclass the ApplicationException class to create package-specific application exceptions. However, a bean provider is responsible for using the standard EJB application exceptions (CreateException, FinderException, RemoveException, javax.ejb.DuplicateKeyException, ObjectNotFoundException) where appropriate.

The ApplicationException class is closely tied to the MessageCatalog. An ApplicationException contains a log and user message that is constructed using the MessageCatalog. In fact, each ApplicationException derivative should have at least one user and log catalog message.

Since an application exception does not, and should not, automatically mark the existing transaction (if any) for rollback, the bean provider must do one of the following before throwing the exception, in order to insure data integrity:

• Ensure that the instance is in a consistent state.
• Mark the transaction for rollback using EJBContext.setRollbackOnly().

The second option is only available when the bean is deployed with Container managed transaction management. Therefore, in order not to tie the bean implementation to a specific deployment, try to avoid using setRollbackOnly at all costs. If this is not possible, consider using a FatalApplicationException.
