Re: Multipart form submission does not work over SSL HTTP2 on Tomcat 9

[Thad Humphries]

I am getting a null returned from HttpServletRequest.getParts() HTTP/2 and
multipart (see http://bit.ly/1TzXd9k). This happens in my own code, as well
as when I try to upload a *.WAR though the manager/html web page. Other
than configuring the connector and the upgrade protocol (see below), what
must be done?

Is it possible for you to test your configuration with the manager
application that comes with Tomcat distribution?
It uses multipart.

I tested it on my side and the manager application is working with HTTP/2
and multipart.

If you are using servlet 3.0+, there's no reason to use a separate
file-upload library.

Use HttpServletRequest.getParts() and related API calls.

I'm not sure if this has anything to do with http2.

I can't speak for Tomcat 9, but for T8 getParameter() won't work on a
multi-part form.  I vaguely recall there's a Tomcat way of getting the
parameters, but I ended up using Apache's FileUpload library which will
generate a list of files and parameters for the request.  Though I have no
idea if FileUpload will work with HTTP2 or not.

Multipart form submission does not work over SSL HTTP2 on Tomcat 9

[Ajay Verma]

Hello,
I'm trying to get multipart forms working in Tomcat 9 over HTTP2 (with TLS 
enabled).

The SSL Connector configuration in server.xml (Tomcat 9) is given 
below  

  
  
  Multipart form submission does not work (the form variable 
values are not retrieved on server in the servlet) with above connector.The 
sample multipart form html code is given below

File 1:
File 2:


I am trying to get form parameters by using the 
getParameter("form_submission_type") method on HttpServletRequest, and it 
returns null under HTTP2. If I remove the line ) it works. But now I am 
not on HTTP2. 

Anyone have any ideas how I can get it to work on HTTP2? 
Thanks in advance for any suggestions and comments.
Ajay
