Answer 1

Java language (and others) needs \\ (double backslash) in Strings in order to read a single \. Your first way should change to

JasperReport report = (JasperReport) JRLoader.loadObject(getServletConfig()
    .getServletContext().getRealPath("\\rpts\\report1.jasper"))

Still, it would be better to check paths using / or even better using File#separator as shown here: File.separator vs Slash in Paths
