How to add my own classes in iReport when I change from Groovy to Java language?

Question

I'm working with iReport and JasperReports, when I began to do my report, iReport by default use Groovy, but I need to change to Java (constrains in my job), I make my report with Groovy and It's works perfectly but when I change to Java language, I get a trouble, because I use a class(fields from java of a class) in my report, so the Mistake is: myfield cannot be resolved or is not a field.

The class that I use to do my report is:

public final class GrupoEstadistico implements Serializable {

    private Estadistico ccDocumento;
    private Estadistico ccNombres;

    //another class that is an attribute of type Estadistico

    private Date periodo;
    private String tipoEntidad;

    //and another primitives atributes: strings, int

    //getters and setters
}

This is the Estadistico class:

public final class Estadistico implements Serializable, Comparable<Estadistico> {

    private String nombreEntidad;
    private int codigo;
    private int numeroConsultas = 0;

    //and aother primitives atributes: strings, int
    //getters and setters
}

And I use all attributes of the class GrupoEstadistico in my report like a fields.

And I use expressions to get the values of each Estadistico like:

$F{ccDocumento}.numeroConsultasanyone

The trouble that I get when I try to compile the report is:

numeroConsultas cannot be resolved  or is not a field.

What I understand is happening is:

iReport not find my class attributes thus this has
iRreport not understand the expressions I use.

This is that I been tried to solve my problem:

add a jar file with the classes required to classpath of iReport.
add the import like: reporte.model.GruoEstadistico in the properties of my report.
And I been edited the xml and I add the tag scriptlet:

 <jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports"
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
 xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" 
 name="ListaConsultaEstadistico" pageWidth="895" pageHeight="595" 
 orientation="Landscape" columnWidth="855" leftMargin="20" rightMargin="20" 
 topMargin="20" bottomMargin="20" 
 scriptletClass="reporte.model.GrupoEstadistico" 
 uuid="b0990d7b-fade-4200-a2ef-fb0416f5a9c2">

UPDATE:

I'm calling my report from the Java code the following way:

/**Create a List of GrupoEstadistico class. */

List<GrupoEstadistico> this.dataSource = new ArrayList<GrupoEstadistico>();

/**Fill my List....*/


JasperPrint jasperPrint= JasperFillManager.fillReport( reportPath,this.parametros,
                 new JRBeanCollectionDataSource( this.dataSource ));

The dataSource is a List<GrupoEstadistico>

But still does not work.

Can anyone help me?

@Nicolai, thanks but not works, when I try to call the getter I get: The method getNumeroConsultas() is undefined for the type Object — Cristian
Which class have field $F{ccDocumento} in jrxml? Is it java.lang.Object? "The method getNumeroConsultas() is undefined for the type Object" — sanBez
And scriptlet is not need for you. Define only fields ccDocumento, ccNombres, etc... in jrxml. And check getters for this members of class — sanBez

Send your object in ireport using java program. Define a field with name of your instance and attribute. e.g. Suppose you send your class instance with grupoEstadistico, define a field in ireport with name "grupoEstadistico.tipoEntidad". and Drag a textfield in any band. RightClick->Edit Expression-> remove ${field}-> double click on your field->click apply It will add you attribute in *iReport *. now if you download your file as pdf format , it will show data what ever you send in this instance.
