[Jasper Reports can't use resourceBundle for internationalization]

Hi,

I want to apply internationalization in my jasper report. Can anyone tell me what am i doing wrong?

 

I have two resource bundles:

• balance_de.properties
• balance_en.properties

My resource bundle looks like this:

•     mainTitle = title
•     secondaryTitle = secondary title

Resource bundles are in the same folder as the class that is using them.

I am loading resource bundle:

HashMap<String, Object> parameters = new HashMap<>();
ResourceBundle resourceBundle = ResourceBundle.getBundle("balance", new Locale("de", "DE"));
parameters.put("REPORT_RESOURCE_BUNDLE", resourceBundle);

In jrxml report i am trying to obtain the mainTitle value from resource bundle:

             <textField>
                <reportElement x="0" y="0" width="798" height="20" uuid="0b25b17c-b0f4-4d46-975d-ffea5c518f28"/>
                <box>
                    <topPen lineWidth="1.0" lineStyle="Solid" lineColor="#000000"/>
                    <leftPen lineWidth="1.0" lineStyle="Solid" lineColor="#000000"/>
                    <bottomPen lineWidth="1.0" lineStyle="Solid" lineColor="#000000"/>
                    <rightPen lineWidth="1.0" lineStyle="Solid" lineColor="#000000"/>
                </box>
                <textElement textAlignment="Center" verticalAlignment="Middle"/>
                <textFieldExpression class="java.lang.String">
                    <![CDATA[$R{mainTitle}]]>
                </textFieldExpression>
            </textField>

However it is not working, and i have no idea why.
