Some of these old discussions might help. Ignore the answers pointing to documention. I once had to dive into a medium size Java web application without documentation and it took me half a day to even find out where data was stored (in a H2 database) nevermind trying to install it or finding out what changed between the repository and what I found on the live server. Ultimately told the client it will be cheaper for them to find another contractor. Best of luck.

I can't believe there are no effective tools for that. Everything looks to be very low-level...
Extremely useful, thank you.
