If I were to print
System.out.println(-Math.abs(-14));
would it print -14 or would it disregard the negative sign on the outside of the Math.abs code?

You will get -14. Please go try your code first to see its behaviour

You should urlencode the JSON
{"StartDate":"20140604","EndDate":"20140630","Range":"10"}
to
%7B%22StartDate%22%3A%2220140604%22%2C%22EndDate%22%3A%2220140630%22%2C%22Range%22%3A%2210%22%7D
The URL will then be
http://192.168.1.7:8080/service-0.0.1-SNAPSHOT/report/genReport/generateReport?reportname=REPORT&doctype=PDF&param=%7B%22StartDate%22%3A%2220140604%22%2C%22EndDate%22%3A%2220140630%22%2C%22Range%22%3A%2210%22%7D
