Multiple file upload is an HTML5 feature. Wicket supports that only in versions 1.5 and up. You need to upgrade to do this.

In 1.5 you use a regular FileUploadField , which will now give you a List<FileUpload> instead of just a single FileUpload . In your markup you put <input type="file" multiple="multiple"/> . The rest is as usual.

Besides, 1.4.9 is ancient . Even if you decide to stay with 1.4.x you really should upgrade to the latest 1.4.x version at least, for many bugfixes, including some relevant to security.
