I use the Primefaces manual example for a wizard, and replace one of the tabs by a simple file upload form. I have all the necessary libraries and filter in web-inf for the file upload to work. Running the project with Netbeans does not show any error (the wizard is displayed and the UI responds), but the file is not uploaded and I get no system message from my fileBean class. Any clue where I make a mistake? Is something wrong with my nested form in the index.html? Thx!

Start by getting rid of the nested forms… you got one surrounding the wizard and one inside the
<p:tab id="upload" title="File upload">Try removing the inner form from the tab and wrap the wizard with
<h:form enctype="multipart/form-data">
