Your exception mapping is likely throwing an exception then... think of it like this -
1 Action gets invoked 2 Oh-No! an exception -> go to the exception page 3 Exception page invoked 4 Oh-No! an exception -> go to #2 Xwork's chain result explicitly checks that an infinite chain sequence isn't happening. That's more or less the only thing the chain result checks, so I would make sure this isn't the case. -Wes On Fri, Sep 11, 2009 at 1:23 PM, Denny Erinjery <denny.erinj...@timelink.com> wrote: > Anybody have any ides about this?? > I try to do an additional action class with redirectAction after the > first chaining using a second action to avoid the 500 error but that > didn't help me, debugging into the ActionChain interceptor from xworks > shows that it went to an infinte error after checking the > chaininghistory > Thanks > > > -----Original Message----- > From: Denny Erinjery [mailto:denny.erinj...@timelink.com] > Sent: Thursday, September 10, 2009 3:04 PM > To: Struts Users Mailing List > Subject: excpetion chaining to custom exception handler issue > > HI, > I'm using a global exception handler action class to get the exception > details and display it on a custom error page. > Following is the struts xml configuration > <global-results> > <result name="Excpetion" type="chain"> > <param > name="actionName">UnhandledExceptionHandler</param> > <!-- param > name="namespace">/namespaceWhereActionIsDefined</param --> > </result> > </global-results> > > <global-exception-mappings> > <exception-mapping exception=3D"java.lang.Exception" > result="Excpetion"/> > </global-exception-mappings> > > > <action name="UnhandledExceptionHandler" > class="com.timelink.falco.wui.struts.handlers.GlobalException"> > <result name=3D"error" > type="dispatcher">/jsp/systemerror.jsp</result> > > </action> > > Once my action class is invoked it will create my exception object using > the current exception set by the struts setter as well as I get more > details about the system at the time of the exception.
