Is there a limit to the file size you can upload with GWT FormPanel and FileUpload?

Question

I recall seeing somewhere that there was a limit of 10MB upload in GWT when using FormPanel and FileUpload , but I can't seem to find any reference to a limit now. Is there one?

Answer 1

There is no reasonable limit* on the client side (or in GWT) of a <input type=file> . That said, it is quite likely that your server has a limit on the size of an upload, so be sure to configure whatever server (and optionally any reverse proxy in use) to use a high enough limit.

* technically, it appears there is a limit - the file cannot be larger than 2^64 bytes (about 18 million terabytes), at least according to MDN.
