Fala galera!
to tentando criar um report em xls a partir de um List (java.util.List) usando o iReport. O problema é que da uns erros, e eu realmente não sei o que estou fazendo errado.
O código é o seguinte:
Collection<Report> reports = createBeanCollection(); // lista de objetos Report, que contém todas as informações que quero mostrar
JRDataSource jrRS = new JRBeanCollectionDataSource(reports, false);
Map parameters = new HashMap();
try {
JasperFillManager.fillReportToFile("c:/users/vitor/report3.jasper", parameters, jrRS);
JasperViewer.viewReport("report3.jrprint", false);
}
catch (JRException e) {
e.printStackTrace();
}
Na linha “JasperFillManager.fillReportToFile(“c:/users/vitor/report3.jasper”, parameters, jrRS);” ele dá o seguinte erro:
java.lang.ClassCastException: cannot assign instance of [Lnet.sf.jasperreports.engine.JRBand; to field net.sf.jasperreports.engine.base.JRBaseSection.bands of type [Lnet.sf.jasperreports.engine.JRBand; in instance of net.sf.jasperreports.engine.base.JRBaseSection

net.sf.jasperreports.engine.util.JRLoader.loadObject(JRLoader.java:88)
net.sf.jasperreports.engine.JasperFillManager.fillReportToFile(JasperFillManager.java:443)
A classe Report é assim:
public class Report implements Serializable{
private Long userId;
private String userEmail;
private String accountIndividualName;
private String username;
private Long borrowerId;
private Long lenderId;
private Date historyDate;
private Date lisFilledCreationDate;
private Date lisListedCreationDate;
private Date lisDeniedCreationDate;
private Date lisFinLess50CreationDate;
private Date lisFinNotAcceptedCreationDate;
private Date lisOkCreationDate;
private Date lPendingCreationDate;
private Date lokCreationDate;
private Date lDeniedCreationDate;
private Date bidDate;
private boolean userValidated;
... getters e setters...
}
Se alguem puder me dar uma ajuda fico muito grato!!
Ah, e o xml gerado pelo iReport é o seguinte:
