Generate report with nested object problem

[abdeulwahabebouamer]

I have a class with nested object. I'm using Bean Collection DataSource. 

 

Here is the class of the Transaction bean

public class Transaction {    private Long idTransaction;    private String observation;    private String observation2;    private DirectionOfTransaction directionOfTransaction;    private LocalDateTime dateTime;    private Account account;    private User user;    private TypeOfTransaction typeOfTransaction;    public Long getIdTransaction() {        return idTransaction;    }    public void setIdTransaction(Long idTransaction) {        this.idTransaction = idTransaction;    }    public String getObservation() {        return observation;    }    public void setObservation(String observation) {        this.observation = observation;    }    public String getObservation2() {        return observation2;    }    public void setObservation2(String observation2) {        this.observation2 = observation2;    }    public DirectionOfTransaction getDirectionOfTransaction() {        return directionOfTransaction;    }    public void setDirectionOfTransaction(DirectionOfTransaction directionOfTransaction) {        this.directionOfTransaction = directionOfTransaction;    }    public LocalDateTime getDateTime() {        return dateTime;    }    public void setDateTime(LocalDateTime dateTime) {        this.dateTime = dateTime;    }    public Account getAccount() {        return account;    }    public void setAccount(Account account) {        this.account = account;    }    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }    public TypeOfTransaction getTypeOfTransaction() {        return typeOfTransaction;    }    public void setTypeOfTransaction(TypeOfTransaction typeOfTransaction) {        this.typeOfTransaction = typeOfTransaction;    }}[/code]

I have problem in JasperSoft community edition. first of all insert my class folder with in class path.

Get Transaction class properties, when i drag & drop field with type like Strin, bigDecimal, to the details section every thing works fine.

But when i drag and drop field declared with custom types like DirectionOfTransaction, Account ..etc (My own class), Japsersoft sutdio can't place them in the details section.

I have also create a variable using some with conditional expression and place in the detail section i get an error:

Here is hte JRXML file:

and her is the code for java program:

 

try {    InputStream inputStream = new FileInputStream("./report/secondReport.jrxml");    JasperDesign jasperDesign = JRXmlLoader.load(inputStream);    JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);    HashMap parameter = new HashMap();    JRDataSource beanDataSource = new JRBeanCollectionDataSource(transactionModel.getTransactionList());    JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameter, beanDataSource);    if (jasperPrint != null) {        JasperViewer.viewReport(jasperPrint);        System.out.println("Printed");    } else        System.out.println("Not able to print");} catch (FileNotFoundException e) {    e.printStackTrace();} catch (JRException e) {    e.printStackTrace();}[/code]
