I have a web app in a jboss application server that gives a not understandable error.

I’m 100% sure it is because it is trying to access a forbidden file system location. Is it possible to profile the program, in particular what is doing step by step (ex. Spawning processes, opening files, writing files, etc)

In addition to strace, also consider sysdig. Sysdig is somewhat like a system-wide version of strace. You can find more information at Sysdig's Github Page

For the type of investigation that you outline (independent of language), strace is your friend. It will tell you what system call are happening. By default it does not trace across fork, but you can enable it.
