-------------------------------------------------------------------

I tried the servlet 3.1 multipart support.

Our (Jena) usage is
 * a servlet filter
 * deployed in any servlet container - normally bundled with Jetty; some users 
deploy a WAR file version in Tomcat et al.
 * `multipart/form-data` is just one possible content-type at the URL endpoint.
 * streaming (errors are handled by being inside a database transaction)

Each servlet container needs custom configuration.

`
{{@MultipartConfig}} only applies to servlets, not servlet filters. 
[https://github.com/jakartaee/servlet/issues/87]

Jetty: the code can set request attribute {{__MULTIPART_CONFIG_ELEMENT}} during 
request processing.

Tomcat needs a setting of a context XML attribute 
{{allowCasualMultipartParsing}}. e.g. set it in {{META-INF/context.xml}}. That 
does at least avoid users needing to specially change the configuration of 
their server.

>             Project: Commons FileUpload

>            Priority: Major
>
> At Piranha, we've migrated to use the new Jakarta namespace.
> One of our dependencies is the Commons File Upload, but the latest version 
> available is 1.4.
> Looking around at the source code, I've found that the code is already 
> prepared for the new Jakarta namespace.
> So, I want to know if there's a plan to release a new version soon. Or at 
> least a 2.0.0 milestone.
