Undertow Options

CommandBox uses JBoss Undertow to power it's lightweight servlet containers. Undertow also powers JBoss Wildfly and has a lot of configurable options, not all of which have first-class CommandBox settings. These low-level settings come in two different categories:

  • Undertow Options - Settings that apply to the servlet and web server aspects of Undertow

  • XNIO Options - Part of the underlying XNIO library which powers all low-level I/O in undertow

Undertow Options

Undertow has its own set of options which can be found here:

To set an XNIO option that CommandBox doesn't already expose with a first-class setting, you can set them into your server.json like so:

server set runwar.undertowOptions.ALLOW_UNESCAPED_CHARACTERS_IN_URL=true

You can also set global XNIO objects that will apply to all servers. Global options will be appended to server-level options.

config set server.defaults.runwar.undertowOptions.WORKER_NAME=myWorker

XNIO Options

XNIO (which is a refined version of NIO (Non-blocking I/O) has its own set of options that apply to the low level network transport functions it provides. You can find the full set of XNIO options here:

To set an XNIO option that CommandBox doesn't already expose with a first-class setting, you can set them into your server.json like so:

server set runwar.XNIOOptions.WORKER_NAME=myWorker

You can also set global XNIO objects that will apply to all servers. Global options will be appended to server-level options.

config set server.defaults.runwar.XNIOOptions.WORKER_NAME=myWorker
