Is there a way to deploy lex files as part of a war file?

yes, you can download them although urls are not always obvious, set the location of lucee-server in web.xml copy your lex files to lucee-server/deploy. when lucee unpacks itself it will find and load them

Thanks mate.. I'll look into this. I'm planning on hosting my own lex files to remove dependency on Lucee domains.. so the urls will be my own. Do you know if the Lucee-server dir is overwritten when the war is unpacked?

if you let lucee unpack itself then it wont overwrite it
