I guess Ron meant Tomcat with the "standalone Servlet container" and didn't
ask for Tomcat to implement the EE web profile ;)

Maybe the last point is because of the classic chicken & egg problem? People
are not writing portable authentication modules, since they know Tomcat
doesn't support them. Because of that few of them are being written and thus
other people do not ask for it.

As Ron already demonstrated a bit, the Servlet Profile of JASPIC should be
relatively easy to support. It's not a complete new feature with a lot of
code that has to be build into Tomcat (like e.g. supporting CDI would

Instead, it's doing something that Tomcat already does, but (more or less)
layering some standardized interfaces on top of that. In fact Tomcat's
( is not
that far away from a JASPIC implementation.
