What is the version number of Undertow?

Communities CommandBox CLI

I’d like to know which version of Undertow is being used in CommandBox 6.2.

Can I retrieve such information on my own by looking at config files or lib folders?

Thanks,
Paolo

Apologies for the delay in posting. Our notifications from the forum weren’t working and I didn’t see this post yet.

The version of Undertow depends on the version of Runwar, which depends on whether you’re using a Jakarta servlet or not.

For the Jarkarta version (Adobe CF 2025, BoxLang, or Lucee 7) we’re using Undertow 2.3.6.Final

For all older javax servlets, we’re using Undertow 2.2.37.Final

I’m sure there’s prolly some Undertow class you can create at runtime to get the version out of, but I’m not sure off the top of my head. There is also a version.properties file inside the io/undertow folder of the Runwar jar inside the CommandBox home which is where we “shade” in the Undertow dependency.
