ExceptionHandler
PrimeFaces provides a powerful ExceptionHandler out of the box with following features:
- featuring support for AJAX and non-AJAX requests
- ability to use error-page configuration in web.xml
- an EL extension called #{pfExceptionHandler} to provide information about the exception
- p:ajaxExceptionHandler component to customize AJAX exception handling on the current view
<div class="card">
<h:form>
<h5 class="mt-0">AJAX</h5>
<p:commandButton action="#{exceptionHandlerView.throwViewExpiredException}"
ajax="true"
value="Throw ViewExpiredException!" styleClass="mr-2" />
<p:commandButton action="#{exceptionHandlerView.throwNullPointerException}"
ajax="true"
value="Throw NullPointerException!"/>
<!-- IllegalStateException is not handled using ajaxExceptionHandlers below, so the error page is shown-->
<p:commandButton action="#{exceptionHandlerView.throwWrappedIllegalStateException}"
ajax="true"
value="Throw IllegalStateException!" styleClass="mr-2"/>
<h5>Non-AJAX</h5>
<p:commandButton action="#{exceptionHandlerView.throwViewExpiredException}"
ajax="false"
value="Throw ViewExpiredException!" styleClass="mr-2"/>
