Solution

The OP calls

String path = scontext.getRealPath("src/main/webapp/relatorios");
JasperPrint jasperPrint = JasperFillManager.fillReport(scontext.getRealPath("src/main/webapp/relatorios")+ File.separator+relatorioNome+".jasper", parametros, dataSource);

i.e. he references files in src/main/webapp/relatorios. This may work in test classes on a development machine where there are source file trees but Maven usually won't put the src folder into the eventually deployed WAR.

In the case at hand, though, the files in question are from src/main/webapp. The content of this folder are copied into the WAR root. Thus,

String path = scontext.getRealPath("relatorios");
JasperPrint jasperPrint = JasperFillManager.fillReport(scontext.getRealPath("relatorios")+ File.separator+relatorioNome+".jasper", parametros, dataSource);

should work. That been said, though,

I'm not sure whether JBoss actually extracts WARs or not. If it does not, there is no real path. Looking at the documentation, though, one reads that getRealPathreturns null if the servlet container is unable to translate the given virtual path to a real path. As the issue is not about a null value, therefore, JBoss seems to extract.
I doubt you want to make your *.jasper files publicly available. In your case they seem to be, though.
