In our case we place all elements to be 'uploaded' in the same FormPanel as the file input element.
Then in our servlet we first retrieve all parts (HttpServletRequest#getParts) after which we use getParameter to read out the filled in form inputs.
The file itself is retrieved via a getPart(name of input here).

Then, when the user is ready to submit the lot, the UI sends the file's key to the server as well as the other data.The server can then move the file data to a permanent home, or mark it as permanent.PaulOn Wed, 12 Sep 2018, 10:06 Ousti Driss, <ousti...@gmail.com> wrote:Hey guys,While browsing on the internet I found a way to upload a file in a gwt app,I managed to reimplement the code and it works just fine using formPanel,It just happens that this file needs to be stored in a mysql database,the problem is before the user selects the file he wants to upload, he needs to pick up two elements from2 combobox,I need those informations so I can build my sql querry, How I can get those fields selected by the userin the upload File servlet?Thanks a lot,
