RE: [OS-webwork] ActionInvocation result

Oops... sorry, my bad.   Does anyone else have any thoughts on this?   I'm not sure about just logging exceptions from an interceptor... I think maybe any exceptions are a problem...   I'm also wondering if it's a good idea to catch these exceptions or if it's better to let them get out to the caller (the servlet in the ww2 case) to be handled...   Jason -----Original Message----- From: John Patterson [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 04, 2003 11:40 AM To: [EMAIL PROTECTED] Subject: Re: [OS-webwork] ActionInvocation result Getting a bit tired Jason?  Hard work answering all these questions!   I was actually asking about the result code returned from the ActionInvocation.invoke() method not the Action.invoke() method.  The later is used to fetch a Result from the action config to execute after the action finishes BUT the former return value is never used.   Also, my logic stated that if the result HAS been executed then we can assume that the result HAS been executed (so don't execute another).  If the Action and Result both complete execution then the property is set to true and any exceptions thrown after this point must be thrown from Interceptors.  Correct?   I have implemented this interceptor and it seems to work fine (uses 1.4 logging however).  Although it has hardly been put through its paces.  I think it would make a useful addition to XWork.   John. ----- Original Message ----- From: Jason Carreira To: [EMAIL PROTECTED] Sent: Tuesday, November 04, 2003 3:30 PM Subject: RE: [OS-webwork] ActionInvocation result The result code is mapped to a result based on the configuration (i.e. "success" is mapped to a JSP, etc)   I'm not sure of your logic... the executed property is there to tell if the result has been executed (maybe it should be renamed)... If the result has not been executed, it could be either an interceptor that had a problem before executing the Action, or the Action itself, or even the Result, since it's executed before the flag is updated.   -----Original Message----- From: John Patterson [mailto:[EMAIL PROTECTED] Sent: Tuesday, November 04, 2003 7:42 AM To: Webwork Subject: [OS-webwork] ActionInvocation result Hi,   What is the the purpose of the result code returned from ActionInvocation.invoke()?  I can't find anywhere in the code that it is used?  Also, any comments on my plan to implement an ExceptionHandlerInterceptor like so:   ExceptionHandlerInterceptor catches all Exceptions and checks to see if the invocation has been executed.  If so then the exception must have been thrown by another interceptor so just log it and do nothing (result has already finished executing).  Otherwise, use the ActionProxy to create the ERROR result and execute it. Thanks,   John.
