java jsf primefaces fileuploader

i tried this example [login to view URL] but its not really working for me xhtml file is ok but the bean is never called and the files are not uploaded. (i am using tomcat7) this project is about fixing this probelm in my project and modifying the primefaces fileuploder: 1. i need arrows for changing the position 2. remove all the upload buttons and make an extra (external button for uploading all at once) 3. generate in folder /uploads a new folder 4. store the images this way: [login to view URL] [login to view URL] [login to view URL] ... 1,2,3... are for the positions the numeration depends on how the user has sorted with the arrows.
