Re: Managing file attachment
Instead of storing the file in the session, why don't you just store the file name and path. If the user doesn't resubmit the request, then check for the file when the session expires and remove the file. I agree storing the file itself is a bad idea, but a reference to the location should be fine. You should prob. move the file to a temporary location. It has been too long since I've used struts1 to help you with the specifics, but I'm pretty sure there is nothing built in to deal with this scenario.

Re: Managing file attachment
Hi Adam, Thanks for your reply, really appreciate it. I am using struts 1.3. The validation is via validation.xml and it kicks in even before the action class can read the file, persistence is later step. The problem is if the do store the file in session in action class and then invoke manual validation i.e. valid current form etc. *The session object will become huge. Then every time i will have to store that file in session and then remove from session. Which doesn't seem a good approach in terms of performance.**. what do you say?* As far client side validation is concerned, the validtion.xml provides powerful ways which might be tough to do i.e. showing error messages etc... Also it will be like redoing the work struts valdition framework has done. * Any other options???.* * Can you guide me to custom the file interceptor any example of that. I know the default destroys the file object as soon as the request has been sent?* * Also is it possible i can get the path of the file like 'c:\files\foobar.txt' and in case of validation error messages read the file from that locaton ???* Please reply..

Re: Managing file attachment
I could be wrong but I believe you'd have to implement your own file upload interceptor and make sure the file is not removed after the execution of the action if a validation error occurs. Then you'd need to re-associate that saved file when the next request occurs. Also what happens if they never resubmit the request. You will have a file sitting around. I can't think of a good way to handle that scenario since your not storing any information in the session or persistence layer and each request is really stateless. Adding client side validation might be your best bet. That way the file isn't even submitted until the form passes validation.

Managing file attachment in struts.....please reply..
Hi, I am having an issue with struts file upload during validation. On the page when there's a validation error, the browsed/attached file drops. Does anyone know a work around it, to have the previously attached file in tact, meaning if i have attached a file and hit submit and got the validation error, the file should still be there, so that i don't have reattach it again. Storing the file in session is out of league as it's not a good approach. Again my problem is if i attach a file and hit submit button and get validation errors defined in validation.xml, i fix the validation error and now i have re-attach that file again since it gets detached. Please reply. Thanks
