The package commons-fileupload has dependencies to the old javax package: https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload/1.5 It is not ready for Jakarta EE and you don't need this package for file uploads because you can use the default servlet methods to retrieve the file (this was the link I sent).
