Package org.imixs.workflow.office.util

Class ImixsExceptionHandler

java.lang.Object
jakarta.faces.context.ExceptionHandler
jakarta.faces.context.ExceptionHandlerWrapper
org.imixs.workflow.office.util.ImixsExceptionHandler
All Implemented Interfaces:
jakarta.faces.event.FacesListener, jakarta.faces.event.SystemEventListener, jakarta.faces.FacesWrapper<jakarta.faces.context.ExceptionHandler>, EventListener
public class ImixsExceptionHandler extends jakarta.faces.context.ExceptionHandlerWrapper
The ImixsExceptionHandler handles Imixs WorkflowExceptions as also EJB Exceptions. In base of a Imixs WorkflowException the ExceptionHandler adds a new FacesMessage with the root cause of the problem. This kind of message can be simply displayed with a <h:messages id="globalMessages" globalOnly="true" /> tag.

In case of an EJB Exception this ExceptionHandler redirects to the page error.xhml page to display a user-friendly version of those exceptions.
