I am trying to create a data table using Jasper reports. I am using a JRBeanCollectionDataSource to execute the report. Here is the subreport I am using:
<?xml version="1.0" encoding="UTF-8"?>

And the corresponding phone bean is
package model;
public class Phone {
private String phoneType;
private String phoneNumber;
public Phone() {
}
public Phone(String phoneType, String phoneNumber) {
this.phoneType = phoneType;
this.phoneNumber = phoneNumber;
}
public String getPhoneType() {
return phoneType;
}
public void setPhoneType(String phoneType) {
this.phoneType = phoneType;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String toString() {
StringBuilder builder = new StringBuilder();
builder.append("\nPhone type: ");
builder.append(getPhoneType());
builder.append("\t");
builder.append("Phone number: ");
builder.append(getPhoneNumber());
return builder.toString();
}
}
When I call JasperFillManager.fillReport, I am getting the following exception:

But I have not defined any field named ‘type’ in Phone bean. Could not understand why this error is coming up. Can someone please help?
Try to use the field declaration like this:
