ireport with struts2

[sathya rajavel]

Hi I have created the report design where the both rows and columns grow dynamically .So in columns i pass the parameters and for rows to grow dynamically i have given the firld names both the params and fields i have given with the extension from DTO.
Now in action class.The fields which are to be displayed i have stored in a list and in struts.xml file for the datasource i have given this list name.Nowthye list contains value.but in pdf its showing null.

    public String printPDF()  {
                              log.info("===========PDF Printing===============");   
                             
                         try 
                            {
                            
                      
                        printpdf.add(operRepDTO.getComp());
                        printpdf.add(operRepDTO.getContSize());
                        printpdf.add(operRepDTO.getProdType());
                        printpdf.add(operRepDTO.getProdDesc());
                        printpdf.add(operRepDTO.getTon());
                        log.info(printpdf);
                       // printpdf=OperRepSer.printOperRep(operRepDTO);
                       
                        
                                }
                                
                           catch (Exception e) {
                              log.info(e);
                              e.printStackTrace();
                           }                                       
                      return SUCCESS;
                          }   

  <action name="printOperReport" class="OperRepAction" method="printPDF">
