Today is a bad day to run a VMWare cluster with thousands of java apps.
I'm not sure what you mean. You can deploy a built binary over your network and run it on all your servers. For example: curl -sSL https://github.com/1lann/log4shelldetect/releases/download/v0.0.2/log4shelldetect_0.0.2_Linux_x86_64.tar.gz | tar -C /tmp/ -zxf - log4shelldetect && /tmp/log4shelldetect -mode list /path/to/scan 2>/dev/null would download and extract the prebuilt binary to /tmp, and run it scanning at /path/to/scan, only outputting paths to potentially vulnerable .jars and ignoring warnings. You can replace the URL with your own build or distribute your own build as you wish.
