but cant make work cakephp.

it works on sever outside cakephp environment, guess have use plugin cant figure out. uses pdf.js , processing-api.js libraries , think problem loading these libraries.

what want user preview pdf wants upload before he/she uploads it

thank in advance.

regards

i finaly found solution this, added: pdfjs.workersrc = '/js/pdf.worker.js'; before pdfjs.disableworker = true;

now works!
