Hi all,
In Tomcat 11 a jersey Api multipart-formdata is registered with Multipart
feature.Also an inbound filter in front reading request.getparamater
fails
with "unable to process parts as no multi-part configuration has been
provided."
In Tomcat 11 it fails.
In Tomcat 10 same setup works continuing parts as empty list.
Is this expected
Yes.
and valid change
Yes.
Parameter parsing in the Servlet spec has been tightened up to fail with
an exception rather than to ignore errors and carry on.
More specifically, these requests were /actually failing/ in Tomcat 10
and not producing any warnings or errors. So the difference is that you
know about the failures, now.
and if so any suggestion how to avoid this?
If you want Tomcat to parse the form data then either:
- configure the target servlet to support multi-part
or
- set allowCasualMultipartParsing="true" on the Context
If you don't want Tomcat to parse the form data:
- don't call any of the getParameter*() methods
- read the body using getInputStream()
- parse the body manually.
