Hi Thomas, I get returned "Page no found" when I navigate through: https://www.linuxquestions.org/questions/linux-server-73/fileupload-class-
I don't understand the relation between the code in my JSP page and the link you provided me: https://docs.oracle.com/javaee/6/tutorial/doc/gmhba.html What do you mean exactly ? Thanks by advance for any indications.

I had the same issue because I used internal Tomcat classes. In the past the servlet specification didn't have methods to deal with multipart uploads. Since Servlet 3.0 there are methods for retrieving the uploads: https://docs.oracle.com/javaee/6/tutorial/doc/gmhba.html I replace the ServletFileUpload and used standard methods like getParts(). This worked for me.
