## javax.faces.webapp
Class PreJsf2ExceptionHandlerFactory

    java.lang.Object
      javax.faces.context.ExceptionHandlerFactory
          javax.faces.webapp.PreJsf2ExceptionHandlerFactory

All Implemented Interfaces:
  FacesWrapper<ExceptionHandlerFactory>

    public class PreJsf2ExceptionHandlerFactory

extends ExceptionHandlerFactory

This `ExceptionHandlerFactory` instance produces JSF 1.2 compatible `ExceptionHandler` instances. The `ExceptionHandler.handle()` method of the `ExceptionHandler` produced by this factory must meet the following requirements

- Any exceptions thrown before or after phase execution will be logged and swallowed.

- The implementation must examine the `Exception` within each of the unhandled exception events. If the `Exception` is an instance of `UpdateModelException`, extract the `FacesMessage` from the `UpdateModelException`. Log a `SEVERE` message to the log and queue the `FacesMessage` on the `FacesContext`, using the `clientId` of the source component in a call to `FacesContext.addMessage(java.lang.String, javax.faces.application.FacesMessage)`

Since:
  2.0

Method Detail

### getExceptionHandler

    public ExceptionHandler getExceptionHandler()

  Description copied from class: `ExceptionHandlerFactory`

  Create and return a A new `ExceptionHandler` instance. The implementation must return an `ExceptionHandler` instance suitable for the environment. For example, in some cases it may be desirable for an `ExceptionHandler` to write error information to the response instead of throwing exceptions as in the case of Ajax applications.

  Specified by:
    `getExceptionHandler` in class `ExceptionHandlerFactory`
  Returns:
    a new `ExceptionHandler` that behaves in a fashion compatible with specifications prior to JavaServerFaces 1.2
