SessionExceptionResolver.java

Hi. I wrote a slightly different version of SimpleMappingExceptionResolver which puts the exception in the http session instead of in the model. In this way it is possible to use a redirect instead of a view and still be able to access the exception to be shown to the user. Using a redirect is usually better than a view since the flow of the application after a redirect follows the normal execution of the program. What do you think? /Roberto |

One possible danger of putting exceptions in the session that I see is
re-displaying 'old' errors. E.g. if for some reason the real exception isn't
put in the session the error page will pick up on the previous exception
that's still there. This can lead to very confusing situations.
Ideally the exception in the session should be removed after it has been
displayed to the user.

I agree with this but this responsibility is of the controller showing
the exception. Besides, if the exception resolver is used correctly, any
new exception will always replace the old one. Of course, if the users
navigates to the "error.html" page without having caused an exception ...
What I am more concerned about is the fact that if showing the exception
generates an exception which generates an exception which generates an
exception... you end up in a infinite redirect to the error.html page
There should be a way to intercept this recursive problem. Ideas?

Any thought about including this resolver in any spring versions?

Hi, I just checked out Spring and Spring modules projects from CVS and they both have build errors due to missing jars in the build path. Is there are anything that had to be done locally to resolve those errors or Eclipse projects just got out of sync? Thanks Eugene |

Weird, as it was ok last time I loaded the project. I will fix it if there's a real issue.

I presume those errors caused by some missing oracle jar. Not sure which one. regards, Eugene Colin Sampaleanu wrote: > What jars are missing in spring itself?

Hi, I am not sure if this list is the right place to ask this. I wonder if WebFlow editor is working in SpringIDE? I tried to build latest code from SVN and managed to run it after fixing some build errors. However I don't see how to bring up visual web flow editor and WebFlow view don't show any webflows, even those I registered in project properties (using numberguess example from WebFlow fistribution). So, I'd really appreciate any clue how to use it. Thanks in advance. Eugene |

Christian could say for sure but I'm almost positive the preview version of Web Flow Editor available now only supports SWF PR3. We've of course had many releases since then. :-) I know the Spring IDE team is starting work back up now that SWF has stabilized on the road to 1.0 GA, but I don't have the latest status there. Christian or Torsten would know for sure - you might want to checkout the Spring IDE forum on forum.springframework.org as well. Keith -----Original Message----- From: spr...@li...
