Workbench: No multipart config for servlet on Jetty 12

[barthanssens]

Current Behavior

When deploying the workbench on Jetty 12, the workbench loads just fine, and a new store can be created.

However, trying to add a statement via the webinterface to this newly created store results in a "No multipart config for servlet" error (even with ee8-annotations module enabled)

Expected Behavior

The statement should be added

Steps To Reproduce

No response

Version

5.0.0

Are you interested in contributing a solution yourself?

Perhaps?

Anything else?

Could be that we need to upgrade to servlet 4:

rdf4j/pom.xml

Line 377 in 2a998c3

<servlet.version>3.1.0</servlet.version>

[barthanssens]

Worth the try, adding multipart-config to various Servlets (via jetty's web.xml override mechanism) didn't make a difference.

[barthanssens]

Upgrading to Servlet API 4 didn't seem to change anything, so back to checking / adding annotations ...

[barthanssens]

Could be due to the cache filters (Tomcat does not really mind, or at least not anymore)
