Explanation/Reference:
Use the @javax.ejb.ApplicationException annotation to specify that an exception class is an application exception thrown by a business method of the EJB. The EJB container reports the exception directly to the client in the event of the application error.
Note:
java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.RuntimeException
javax.ejb.EJBException
javax.ejb
public class EJBException
extends java.lang.RuntimeException
The EJBException is thrown to report that the invoked business method or callback method could not be completed because of an unexpected error (e.g. the instance failed to open a database connection).
Example:
The following ProcessingException.javafile shows how to use
the @ApplicationExceptionannotation to specify that an exception class is an application exception thrown by one of the business methods of the EJB:
package examples;
import javax.ejb.ApplicationException;
/ **
* Application exception class thrown when there was a processing error
* with a business method of the EJB. Annotated with the
* @ApplicationException annotation.
* /
@ ApplicationException()
public class ProcessingException extends Exception {
