Dynamic Jasper gives a blank report !!!

[Jackeline161]

Hello everybody 

I use the api Dynamic Jasper for generating my dynamic reports but i have a big problem, the code seems correct but it gives me a blank report it doesn't build anything, title columns data... 

 

The code that I use is like this :

---

public String ToPdfFormat() throws ColumnBuilderException {

 

try {

 

 DynamicReportBuilder dynamicReportBuilder = new DynamicReportBuilder();

 

   // configure report-level settings

   dynamicReportBuilder.setReportName("Some").setTitle(g_titre);

 

   dynamicReportBuilder.setPageSizeAndOrientation(Page.Page_Letter_Landscape());

 

   // add id column to report

   ColumnBuilder columnBuilderID = ColumnBuilder.getInstance();

 

   columnBuilderID.setTitle("ID");

   columnBuilderID.setWidth(180);

   columnBuilderID.setFixedWidth(true);

   columnBuilderID.setColumnProperty("ID", Integer.class.getName(), "@id");

 

   dynamicReportBuilder.addColumn(columnBuilderID.build());

 

   // add name column to report

   ColumnBuilder columnBuilderName = ColumnBuilder.getInstance();

 

   columnBuilderName.setTitle("Name");

   columnBuilderName.setWidth(180);

   columnBuilderName.setFixedWidth(true);

   columnBuilderName.setColumnProperty("Name", String.class.getName(), "@name");

 

   dynamicReportBuilder.addColumn(columnBuilderName.build());

 

   // add email column to report

   ColumnBuilder columnBuilderEmail = ColumnBuilder.getInstance();

 

   columnBuilderEmail.setTitle("Email");

   columnBuilderEmail.setWidth(180);

   columnBuilderEmail.setFixedWidth(true);

   columnBuilderEmail.setColumnProperty("Email", String.class.getName(), "@email");

 

   dynamicReportBuilder.addColumn(columnBuilderEmail.build());

 

   // add salary column to report

   ColumnBuilder columnBuilderSalary = ColumnBuilder.getInstance();

 

   columnBuilderSalary.setTitle("Salary");

   columnBuilderSalary.setWidth(180);

   columnBuilderSalary.setFixedWidth(true);

   columnBuilderSalary.setColumnProperty("Salary", Integer.class.getName(), "@salary");

 

   dynamicReportBuilder.addColumn(columnBuilderSalary.build());

 

   // build a datasource representing the XML file

   //Session session = sessionFactory.getCurrentSession();

//    List list = session.createQuery("select * from tab_clas_obj").list();

   DynamicReport dynamicReport = new ReflectiveReportBuilder (g_listCla).build();

   

   // build JasperPrint instance, filling the report with data from datasource created above

   JasperPrint jasperPrint = DynamicJasperHelper.generateJasperPrint(

       dynamicReport,new ClassicLayoutManager(),g_listCla);

   

   // export to pdf

 

   JasperExportManager.exportReportToPdfFile(jasperPrint, "C:\MyReport1.pdf");

 

}
