Hello Peter,
It seems as if you are missing the Apache Commons Logging library. Please try downloading it and run the scenario again.
Furthermore, to make sure everything is okay in the definitions file and the scenario you are running, I would appreciate if you could attach the files related to the definitions file and the scenario so we can test it on our environment and try to investigate this problem further.

Regards,
Itai Peri

Hi everyone,

Regarding the definitions file: this is just for testing purposes, so we're using the DOSAttack2.json file supplied with Proton (https://github.com/ishkin/Proton/blob/master/docker/DoSAttack2.json). Were there any changes to the JSON syntax since May?
Regarding the scenario, the steps are documented in the Dockerfile (https://github.com/ishkin/Proton/blob/master/docker/Dockerfile). It seems that the locations of the WAR files have changed recently (last week), so we might need to rework it. I've yet to take a closer look at this, but if this is the case, is this project structure the final one (for the currently foreseeable future)?

Also, regarding the ACL library. I haven't seen this requirement in the Installation and Administration Guide. Should we add this library to the classpath of Tomcat? What's the correct integration procedure? If this library is needed, wouldn't it be better that it's bundled inside the WAR files (not sure it's technically possible, but from a licensing standpoint bundling Apache libraries for Proton isn't an issue).

Thanks!

Andrei

Hello Peter,
Yes, the file structure of the project has changed, and that might also be the cause of the missing library. It should be fixed now with the latest version of the project on github.
Furthermore, can you please tell me what are the exact actions you have taken while trying out your scenario? which POST/PUT commands have been sent? This will allow us to better understand the problem.

Regards,
Itai Peri

Docker was fixed, integration issue was solved
