How to map property names in POJO to field name .jrxml file ?

[tranvi3t]

Hi everyone,
I'm using JasperReports library to generate reports from my Java classes. I'm wondering if there is a way to map property names in my Java classes to field name in the .jrxml report template file, instead of having to follow the exact field names in the .jrxml?
For example, I may have a Java class with a field "customerName", but in the .jrxml file I want the field to be called "customer_name" instead. Is there a way to specify this mapping, so I don't have to change my Java class field names?
Does there exist any annotation like @Field that can achieve this?
Any help would be greatly appreciated.

Thank you!

You can specify the mapping of a report field to a property name in the Java class using the net.sf.jasperreports.javabean.field.property property.

For instance

    <field name="customer_name" class="java.lang.String">        <property name="net.sf.jasperreports.javabean.field.property" value="customerName"/>    </field>[/code]

I appreciate the suggestion. However, my issue is that I need to map the property names in the Java class to the field names in the .jrxml report template file, instead of the other way around. I'm exploring other options, such as creating a custom data source or using a third-party library that supports this type of mapping. Thank you for your help

JasperReports relies on the JavaBeans standard to resolve object properties (via Commons Beanutils), so you can use the mechanisms defined in the standard to register property names to be resolved from reports.

For instance you can create a BeanInfo class and define the customer_name property:

public class CustomerBeanInfo extends SimpleBeanInfo {    @Override    public PropertyDescriptor[] getPropertyDescriptors() {        try {            return new PropertyDescriptor[] {new PropertyDescriptor("customer_name", Customer.class, "getCustomerName", null)};        } catch (IntrospectionException e) {            throw new RuntimeException(e);        }    }}[/code]
