java-app container won't open a listening port on 8080

[dbodden-pesa]

Describe the issue
I followed the directions (needed to modify the md5 to md5sum in the DeployProject.sh but otherwise the containers built and started OK).

To Reproduce
Steps to reproduce the behavior:

1. Run DeployProject.sh
2. wget http://localhost:8080/
3. Connection reset by peer.

Expected behavior
Like in the docs, I expect to get an http response, and maybe a page w/ the API information.

Screenshots
