I Also try::::

try{
    Connection con=DriverManager.getConnection("jdbc:odbc:projectCon","","");
    JasperDesign jd=null;
    JasperReport jr=null;
    JasperPrint jp=null;
    System.out.println("Trying to load jrxml");
    jd=JRXmlLoader.load("D:\\classic.jrxml");
    System.out.println("JRXml loaded");
    jr=JasperCompileManager.compileReport(jd);
    System.out.println("Compiled");
    jp=JasperFillManager.fillReport(jr,new HashMap(),con);
    JasperExportManager.exportReportToPdfFile(jp,"D:\\rep.pdf");
    }catch(Exception e){
            e.printStackTrace();
    }

   
OUTPUT:

Please some give any solution>>>>>>>>>>>>>>>>

[haiku]

"java.lang.NoClassDefFoundError" and "java.lang.ClassNotFoundException" usually mean a missing class or library.

You are obviously still missing some libraries beside the ones you mentioned.
In the first case it would be "commons-logging-x.x.x.jar".
In the second case - "commons-digester-x.x.jar".
