Multi-Engine Support

You can specify the CFML engine via the command line arguments:

CommandBox> start cfengine=adobe@9

This will start an Adobe ColdFusion 9 server in your webroot. That's it!

By default, CommandBox uses the cfengine slug to search for the engine on ForgeBox. The format is slug@version where the version is optional. Ortus Solutions maintains the versions of the engines available on ForgeBox.

Supported engines are:

  • Adobe ColdFusion 9 **
  • Adobe ColdFusion 10
  • Adobe ColdFusion 11
  • Adobe ColdFusion 2016
  • Adobe ColdFusion 2018
  • Railo 4.2
  • Lucee 4.5
  • Lucee 5

Here are some examples:

# Start the default engine
CommandBox> start

# Start the latest stable Railo engine
CommandBox> start cfengine=railo

# Start a specific engine and version
CommandBox> start [email protected]

# Start the most recent Adobe server that starts with version "11"
CommandBox> start cfengine=adobe@11

# Start the most recent adobe engine that matches the range
CommandBox> start cfengine="adobe@>9.0 <=11"

Engines are downloaded and stored in your CommandBox artifacts folder. You can view your engines and clear them using the standard artifacts commands:

CommandBox> artifacts list

# Removes all adobe servers currently in the artifacts
# These servers will need to be re-downloaded the next time they are started
CommandBox> artifacts remove adobe

** Note: Adobe ColdFusion 9 does not support the latest Java 8. To run ColdFusion 9 you must use an older version of CommandBox 3.x on Java 7 or run CommandBox 4.x on Java 8 update 92 or earlier. Several people are doing this, but beware your mileage may vary.

ColdFusion Admin settings

While Lucee asks for a password the first time running the admin, ColdFusion requires a username and password when CommandBox sets it up. The default username and password for the Adobe ColdFusion servers used are:

  • Username: admin
  • Password: commandbox

WAR Support

Additionally, CommandBox can start any WAR given to it using the WARPath argument.

CommandBox> start WARPath=/var/www/myExplodedWAR
CommandBox> start WARPath=/var/www/myWAR.war

If you run a regular start command inside of a folder that has a /WEB-INF/web.xml file, CommandBox will treat that folder as a WAR.

Custom Engines

The cfengine parameter can accept any valid CommandBox endpoint ID. That means it can be an HTTP URL, a Git repo, a local folder path to your company's network share, or a custom ForgeBox entry you've created. As long as that endpoint resolves to a package that contains these files, you're good:

  1. box.json
  2. Engine.[zip|war] (file name doesn't matter)

CommandBox will download the package, unzip it and use the WAR/zip file as the engine for your app.

Normally, the artifacts cache isn't used for non-ForgeBox packages, but CommandBox will only download the engine once per server and then assume the file hasn't changed. You will need to forget the server to trigger a new download.

Here's an example of starting up a web server using a direct download link to a package containing a WAR file:

CommandBox> start cfengine=http://downloads.ortussolutions.com/adobe/coldfusion/9.0.2/cf-engine-9.0.2.zip

server.json Configuration

You can set the cfengine and other related configuration options in your server.json to use them every time you start your app.

CommandBox> server set app.cfengine=adobe
CommandBox> server set app.WARPath=/var/www/my-app

These commands would create the following server.json

{
    "app":{
        "cfengine":"adobe",
        "WARPath":"/var/www/my-app"
    }
}

Just a reminder that starting a server with any command line arguments will save the arguments to your server.json by default.

CommandBox> start cfengine=adobe@9

This command would add adobe@9 to your server.json. If this is not what you want, you can append saveSettings=false or even --!saveSettings when you start your server and CommandBox will not save the arguments you specify to your server.json.
