        JasperPrint jasperPrint   = new JasperFillManager.fillReport(jasperReport,null,connection);      
        JRViewer viewer  = new JRViewer(jasperPrint);

JasperCompileManager.compileReport and JasperFillManager.fillReport are static methods.

The syntax you're using on the right hand sides of the assignments

new JasperCompileManager.compileReport(" C:\\Users\\PC\\Desktop\\fxmlTest\\src\\fxmltest\\newReport.jasper")
new JasperFillManager.fillReport(jasperReport,null,connection)

tells the compiler to invoke the constructors of the static inner class compileReport in JasperCompileManager and fillReport in JasperFillManager respectively. (Or alternatively the constructors of the classes fillReport in the JasperCompileManager package and fillReport in the JasperFillManager package.) However those classes don't exist which is why you get the compile time error. You need to remove those new keywords:

JasperReport jasperReport = JasperCompileManager.compileReport(" C:\\Users\\PC\\Desktop\\fxmlTest\\src\\fxmltest\\newReport.jasper");
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,null,connection);
