I am a beginner at Spring and I was wondering why my ModelAttribute did not populate (All the values were null)

I want to create a multipart from that allows me to upload a csv file as well as the type of CSV file too.

My codes are as such:

In the CSVUpload-portlet.xml:



CSVUploadPortlet.java (Controller)

CSVFileUploadVO.java


Form JSP

I know it seems like asking you to help solve a problem for me but I've been stuck on this for 8 hours, reading every resource and stackoverflow website i could google on. But despite that, I wasn't able to find anything.

Thank you for your help in this. Please let me know if I missed anything out.
 
With a little knowledge, a cast iron skillet is non-stick and lasts a lifetime.
