upload works well in a .html file but when I call it from a .xhtml file it shows an error

Hi it´s very fun because it works well if I run it(upload.html) alone but if it´s called from a .xhtml file in that case an error happens.

I have asked this before in "Java in general" but I think it fails because it´s inside a JSF app.

I have tried with all .jar´s from 2005 to now, and it doesn´t works.

The error is:

The servlet code is as follows:

package servlet;
