Error "Unable to process parts as no multi-part configuration has been provided" when uploading file

Question

I am trying to upload an file via a form in a JSP file, but I'm getting this error. The servlet already has the @MultipartConfig notation. I'm using servlet 3.0 and apache tomcat 8.

Error message:

java.lang.IllegalStateException: Unable to process parts as no multi-part configuration has been provided

on line

Collection<Part> parts = request.getParts();`

With Tomcat 8.5 and Servlet 3.1 annotation `@javax.servlet.annotation.MultipartConfig` above servlet is enough for me to make it working — Grigory Kislin, Mar 20 '17 at 23:12

I had to add

allowCasualMultipartParsing="true"

on context tag inside context.xml

You should put it into the webapp's element of Webapp context.xml or or Tomcat's server.xml: – Green Root Oct 15 '16 at 16:52
You should put it into `MyProject/Web Pages/META-INF/context.xml` – Dariush Jafari Apr 16 '17 at 08:22
