Yes, I have commons-fileupload-1.1.1.jar and its dependent jar file
commons-io-1.3.1.jar.
In fact, I´ve uploaded files from the two ways I explained in my first mail,
but I don´t know which one is better (Struts upload file or commons upload
file) due to the disadvantages I´ve found for every one and that I´ve put
forward.

with regards to commons-file upload did you upload the latest
fileupload.jar into your webapp/AppName/WEB-INF/lib ?
