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: <?xml version="1.0" encoding="UTF-8"?><!-- Created with Jaspersoft Studio version 6.2.2.final using JasperReports Library version 6.2.2 --><!-- 2016-06-11T18:35:06 --><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="secondReport" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20" uuid="4a30fc90-411a-46d8-b4f3-ba259634b3cc"> <property name="com.jaspersoft.studio.data.defaultdataadapter" value="New Data Adapter "/> <queryString> <![CDATA[]]> </queryString> <field name="directionOfTransaction" class="bean.DirectionOfTransaction"/> <field name="observation" class="java.lang.String"/> <variable name="dirVar" class="java.lang.String"> <variableExpression><![CDATA[((DirectionOfTransaction) $F{directionOfTransaction}).equals(DirectionOfTransaction.CREDIT)) ?
