Passing a generated list as a datasource

[Jackeline161]

Hello everybody 

I have a problem with passing a list as a datasource for my report, the list has a type not primitif (g_listCla = new ArrayList<Cla>() )so I ask if it's possible to do it because it doesn't work for me :s

 

There is the method that i use :

 

public String ToPdfFormat() throws ColumnBuilderException, ClassNotFoundException {

 

try {

 

System.out.println("g_titre :"+titreEtat);

System.out.println("g_listCla:"+g_listCla.size());

FastReportBuilder drb = new FastReportBuilder();

DynamicReport dr = drb

.setTitle(titreEtat)

.setSubtitle("This report was generated at " + new Date())

.setPrintBackgroundOnOddRows(true)

.setUseFullPageWidth(true)

.build();

 

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

   JasperPrint jasperPrint = DynamicJasperHelper.generateJasperPrint(

       dr,new ClassicLayoutManager(),g_listCla);

   

   // export to pdf

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

}

 

 

The list is already filled in the other method when my dynamic query is generated so i wish to pass the list directly to my report , please help me !!!!
