Including external libs in CommandBox CLI doesn't work?

Communities CommandBox CLI

Hello,

I’ve got this cfml script I need to run in which I have to use the Java’s ComputeCRC32 class.

The Jar/Class file for it is under C:\mysite\config\shared\lib\

In CommandBox CLI (v. 5.2.1+00295), I tried adding a global custom lib as described in:

https://commandbox.ortusbooks.com/embedded-server/configuring-your-server/adding-custom-libs#global-custom-libs

config set servers.defaults.app.libDirs=C:\mysite\config\shared\lib\

Then issuing a config show servers.defaults.app.libDirs shows my set path.

However, even after doing so, when I try my script in the CLI, it fails complaining it cannot find ComputeCRC32 :

CommandBox> execute C:\path\to\myscript.cfm
Error executing C:\path\to\myscript.cfm:
ERROR (5.2.1+00295)

cannot load class through its string name, because no definition for the class with the specified name [ComputeCRC32] could be found caused by (java.lang.ClassNotFoundException:ComputeCRC32;java.lang.ClassNotFoundException:ComputeCRC32 not found by lucee.core [46]:wink:
caused by: lucee.commons.lang.ClassException
cannot load class through its string name, because no definition for the class with the specified name [ComputeCRC32] could be found caused by (java.lang.ClassNotFoundException:ComputeCRC32;java.lang.ClassNotFoundException:ComputeCRC32 not found by lucee.core [46]:wink:

FYI: I am loading this ComputeCRC class in my script with :

<cfset oMD5 = CreateObject(“java”, “ComputeCRC32”).init()/>

How can I properly have CommandBox CLI load all my custom shared libs? What am I missing ?

UPDATE : I’ve tried simply starting the commandbox server with my required libs folder like so :

server start libDirs=C:\mysite\config\shared\lib\

and yes, this allows me to open my web browser ( http://127.0.0.1:54536/ ), click on myscript.cfm, and it’ll work. No problem loading the ComputeCRC class.

This isn’t what I need though. I need to be able to run it directly as a script in the CLI.

Thanks for your time.
Pat.

Hi, you’re confusing two different features of CommandBox. Well, three actually.

  • Starting up a web server. The instructions you were following was exclusive to starting up a server. This won’t have any effect on command-line scripts.
  • Doing one-off .cfm executions from the command line. This is an older and very simple method of running CLI code which doesn’t have very may features. I would avoid this in favor of the third bullet.
  • Task Runners. These are the modern solution to doing CLI scripting in CFML and have tons of features, including the ability to load arbitrary jars at run time.

Thanks for your reply! I’ll look at the task runners, as you suggested.
