Hi Rod,
I would assume you are using TomEE 9. x milestone release because you are
using the Jakarta namespace. If this is not the case, you can find the
latest TomEE 9.x.x-M release here https://tomee.apache.org/download.html
Indeed your app packaging seems to be missing the actual servlet class, a
tree command to the exploited .war does not show the class file for
LoggerServlet.java at all.
