Generate report with nested object problem

Posted on June 11, 2016 at 10:40am

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;
    }
}

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();
