Nothing obvious. It is AJP so that suggests the proxy is closing the connection before Tomcat expects it to. That might happen for a 400 response but to be honest, I'd expect the proxy to read the full response before closing the connection. There was some tightening up of HTTP request header validation that might cause a few more 400 responses but I'd be surprised since the proxy should have rejected those requests before forwarding them anyway. The extra checks are for HTTP headers without names. i.e.: : ValueButNoName Maybe check if the client is sending such a header?

The quickest fix is probably option 1: Use the Tomcat migration tool for Jakarta EE to convert commons-fileupload-1.5.jar from from Java EE to Jakarta EE and then use the converted JAR rather than the original. The best solution is probably the one Thomas pointed out: Option 4: Stop using commons-fileupload-1.5.jar and use the methods provided by the Servlet API to handle file uploads.

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.

Thomas
