Hi, I want to know if I can create a Bean like: List<Object, List<Object>> and pass it to a report, to show a Dotter graph where I have multiple column values, The thing is that the secon List can have 2 or more elements and I don't know on runtime! like this: Value 1Value 2Value 3Value 4Value 5Serie 110080100180100Serie 2100100808070Serie 3 And, in other time I only need value 1 and value 2 and in other time could be 20 Value commands. I'm using eclipse rcp, with Jasper Reports 4.1.2. I know is old, but i need it ! This is a sample on how I pass data to the reports Map<Object, Object> parameters = new HashMap<Object, Object>(); parameters.put("anio", anio.getAnio()); parameters.put("logo", "/images/logo.jpg"); parameters.put("filial", filial); parameters.put("f", cruzas.get(0).getFilial()); //Tomo Primer Filial List<CruzaDTO> contenido = generarContenido(cruzas, filial); JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(contenido); JasperReport report = (JasperReport) JRLoader.loadObject(FilialesReportGenerator.class.getClassLoader().getResourceAsStream("reportes/FilialesLibro.jasper")); print = JasperFillManager.fillReport(report, parameters, ds); Thanks

ok for that.... and after that ? can you give an example ? Best Regards Post Edited by nicolas400 at 12/09/2011 21:18

Hi, I have a SQL query that si a sort of PIVOT table, like sales by person and period query. The common problem is that I don't know how many sales-persons do I have at some time. so the query should have some fixed columns as id and period, and some variabe columns as persons ! Is design mode the report looks great, but what appends when I run this on the real application ? I want to know if there is a way for creating series in the report on the fly ? I'm using .jasper files, so the report is compiled when i use it on the application. Best Regards Nicolas

Sorry, I told you I'm a newby ... watching again and again the source code ... one parameter to the method : print = JasperFillManager.fillReport(report, parameters, ds); is an object, but the las one (ds) is the datasource !! so there is the detail ! Although teh repòrt compile, my questin still activo for the issue about classpath ...

Hy, I'm quite newby to Jasper Report, I'm upgrading an application that was developed a few years ago. So I'm upgrading som reports. I'm working with an old version of library (2.0.3) and iReport (2.05). My question is, the report has a parameter that is an Object of mi application, so the DataSource is allway an object, never gos to the database directly. That object got a property that is a List. @Entity@Table(name="Ensayos")public class Ensayo implements Cloneable { private Integer id; private Integer anio; private String epoca; private String nombre = new String(); private String descripcion = new String(); private Date fechaSiembra; //private Localidad localidad = null; private String localidad; private Integer cantidadCruzas; private Integer cantidadRepeticiones; private Integer parcela; private List repeticiones = null; private Date fechaCreacion = null; private Date fechaImportacion = null; private Date fechaExportacion = null; private Date ultimaModificacion = null; private boolean activo = true; private boolean replicado = false; //private boolean realeatorizado = false; //private Integer cantidadTestigos; private boolean seleccionada = false;} So, in the detail section I have a lot of Fields, that use attributes of object for example; $F{peso}[/code]So my question is: how jasper know how to map report field $F{peso} to the attribute peso in Repeticion class ? And anoter issue that I have is that althoug I add the bin folder, root folder an model folder to the menu option: Options->ClassPath, I allway get the error on design that the class ar.com.cse.balanza.model.Ensayo is not found ! Any help will be appreciated. Best regards Nicolas
