I restarted Jetty to re-read global.xml. But when I put $urlEncoder.encode("$entityID", "utf-8") in my login.vm, Velocity gives me back a literal string. Same for when I make it $custom.urlEncoder.encode("$entityID","utf-8").

The bean is exposed in the template as a variable called "custom". [1] 
For some detailed discussion and examples, see the original Jira issue. [2]

Since in this case the custom object is a Map, if you defined an entry
in the map with key "foo", you reference in the Velocity template like:

$custom.get("foo")

and Velocity supports some syntactic sugar variations for some types,
like lists arrays and maps:

$custom["foo"]

Full usage possibilities you can glean from the Velocity user guide
docs. [3]
