If possible check if Jboss is listening on the port:

if curl -Is http://localhost:80/ > /dev/null then echo OK else echo FAIL fi 

You just need one external program: curl

Edit:

Another approach is to test for a specific content, say Contact on the web page. Only if the webserver is running and there is a connection to the database, it will respond correctly.

if grep -qc "Contact" <(curl -s http://localhost/) then echo OK else echo FAIL fi 

The construction <(curl ...) (Process Substitution) will be seen by grep as a file. curl has option -s for silent to avoid transfer progress. grep has option -qc to suppress output and count the occurrence of the matched text. If one or more count of Contact the result is OK (exit code 0).
