If PrimeFaces file upload does not work, mostly the reason will be that the prependId attribute was not set to false in the h:form. After the user browses the file nothing happens and we are left wondering as there is no JavaScript error.

I have configured the PrimeFaces file upload as below in one of my UI page.

<h:form id="myform" enctype="multipart/form-data" prependId="false">
 <p:fileUpload fileUploadListener="#{userprofile.handleFileUpload}"
 allowTypes="*.jpg;*.png;*.gif;" description="User Profile Image"/>

 </h:form>
