jetty 9.0.4 -> 9.1.2: WebServlet not loading any more

Question

Upgrading a servlet from jetty 9.0.4 to 9.1.2. My simple servlet does not get initialized any more when running against 9.1.2. Here is a diff generated over the two versions visualized by running mvn dependency:tree against my server distribution maven project:

I'm registering the servlet class using web.xml. Any hints? I know that is not much information but maybe someone had similar problems when upgrading to 9.1... It is really only a very simplistic WebServlet class and I could not even find a guide on how to upgrade such stuff. A list of what changed (stuff that matters) would be helpful, too... I mean not simply a ChangeLog.

I don't even get an error, so jetty 9.1 seems to ignore the web.xml completely...??

Answer 1

The jetty.home var's content has changed and is now available using the jetty.base reference. I was pointing to the wrong apps dir.
