Problems with FileUpload (on GAE) - how to avoid DiskFileItem?
Hello, I trying to implement a file upload for my wicket application, which should be deployed on Google App Engine (GAE). Since GAE does not allow to spawn new threads, I cannot make use of DiskFileItem due to its use of FileCleaner. The problem is that a DiskFileItem gets instantiated in the MultipartServletWebRequest, which results in an AccessControlException even before the submit method is called (which would allow to parse the request by hand) Thus, I would like to ask if anyone has a hint how to deal with that problem and avoid the instantiation of DiskFileItem? Thanks a lot in advance, andr - To unsubscribe, e-mail: users-unsubscr...@wicket.apache.org For additional commands, e-mail: users-h...@wicket.apache.org

MultipartServletWebRequest has a constructor that allows you to pass in your own fileitemfactory WebRequest has a newMultipartWebRequest that you can override to create a multipartservletwebrequest with your own fileitemfactory... -igor On Tue, Feb 16, 2010 at 10:21 AM, A.

Re: Problems with FileUpload (on GAE) - how to avoid DiskFileItem?
Thanks for that quick response, igor. I created now a very basic and (bad ,-) implementation of FileItemFactory, does not write to disk and doesn't spawn threads. With respect to using common-fileupload on GAE, I read about fileupload's new Streaming API. However, I have currently no clue how to integrate it with Wicket. Do you have any hints for that? thanks, andr On Tue, Feb 16, 2010 at 7:51 PM, Igor Vaynberg igor.vaynb...@gmail.comwrote: MultipartServletWebRequest has a constructor that allows you to pass in your own fileitemfactory WebRequest has a newMultipartWebRequest that you can override to create a multipartservletwebrequest with your own fileitemfactory... -igor On Tue, Feb 16, 2010 at 10:21 AM, A.

There is one already done. Someone post it in the official GAE mail list. Try to look for it. I will try too.
