[Holger Klawitter]

Frank,

you Servlet is not connected to any url.
You need a servlet mapping with a url-pattern
specifyng which url to reply to.

Tomcat 11 & Request Attributes

[Dan McLaughlin]

We use Shibboleth SP, which passes request attributes from Apache over AJP
to Tomcat; after upgrading from Tomcat 10.1 to Tomcat 11, the request
attributes aren't coming over.  Does anyone know of anything that changed
in Tomcat 11 that might affect request attributes being passed over AJP?

Thanks,

Dan
