The Deployer isn't in the list of MBeans visible in your JConsole
screenshot, which is probably why you can't connect to it.

I don't know why that is, but presumably the embedded code doesn't
enable it.

This could be in correlation to the exception above.

The two things are not related.  The empty array refers to child objects
of the servlet (should there be any? no...), not the webapp.
