Why am I getting an "Error retrieving field value from bean", "Caused by Unknown Property on class"

Posted on May 1, 2017 at 7:06am

Hello everyone, this is my first time posting here.

I have a jasper report template jrxml that I am trying to fill with the information from a specific JavaBean class.

This class doubles as an entity for the Java Persistence API (JPA ) and thus maps directly to a database.

Here is my Bean class:

package main.java.gls.entities;

import main.java.gls.entities.util.JobAmount;

import java.io.Serializable;

import java.math.BigDecimal;

import java.util.Collection;

import java.util.Date;

import javax.persistence.CascadeType;

import javax.persistence.Column;

import javax.persistence.EmbeddedId;

import javax.persistence.Entity;

import javax.persistence.JoinColumn;

import javax.persistence.Lob;

import javax.persistence.ManyToOne;

import javax.persistence.NamedQueries;

import javax.persistence.NamedQuery;

import javax.persistence.OneToMany;

import javax.persistence.Table;

import javax.persistence.Temporal;

import javax.persistence.TemporalType;

@Entity

public BigDecimal getAmtApplied() {

}

//amount billed minus amount applied.

public BigDecimal getAmtDue() {

}

My JRXML looks like this:

I saw this post: http://community.jaspersoft.com/questions/527187/nosuchmethodexception-u... and have tried all of the possible solutions that I have found in this and other posts/articles, but I still can't seem to figure out what's going on, whener I run my application I get the following error:

You need to use the lowercase property name for the field:
