I am creating an Google Appspot - Wicket application and want to allow users to upload a file. This file can be upto 15MB, since Google uses a limited JRE it is not possible to create Files.
When setting DefaultMaximumUploadSize to 15MB nothing changes, Appspot still throws a SecurityException. Wicket is not really using the DefaultMaximumUploadSize setting at all, it is passed along the multipart handling but not used. The DiskFileItemFactory is not receiving the DefaultMaximumUploadSize and sticks to a default value of 10240.
I am unable to make a patch file at the moment, can make one later if need be. Here is the required change:
MultipartServletWebRequestImpl.java:90 is currently:
this(request, filterPrefix, maxSize, upload, new DiskFileItemFactory(Application.get().getResourceSettings().getFileCleaner()));
and it should be:
this(request, filterPrefix, maxSize, upload, new DiskFileItemFactory(maxSize, null, Application.get().getResourceSettings().getFileCleaner()));
