Hi, I´m trying write wicket application for Google App Engine. App Engine has some restrictions, one of them is, that you can´t work with filesystem. I´m trying upload images with FileUploadField, but i get AccessControlException. Looking through source code i found there is DiskFileItemFactory, which puts large files (over 10kB) to temp files. Is there any way to redirect all data storing to memory?
I also found, if I upload small file (smaller than 10kB) - DiskFileItemFactory store it in memory, but there is some FileCleaner class which cleans temp files and spawns new Thread (which is also restricted in App Engine). So it fails again on AccessControlException. Have you anybody solved problems with file uploads on App Engine? Thanks
