iReport: How to format date based on French locale

问题

I have a problem with formatting date in iReport

An my pc I configured the locale language as French but when the iReport generate the reports I find the date formated with English locale.

Here is a few code from my jrxml file :

<band height="41" splitType="Stretch">
    <textField pattern="dd/MM/yyyy h.mm a">
        <reportElement uuid="fb711e77-c949-4a99-9b52-109aae00c8ed" x="87" y="19" width="100" height="20"/>
        <textElement/>
        <textFieldExpression><![CDATA[$P{datenow}]]></textFieldExpression>
    </textField>
    <staticText>
        <reportElement uuid="51fb76a0-829e-4c36-b474-3ff9c7d4c239" x="41" y="19" width="48" height="20"/>
        <textElement>
            <font isBold="true" isItalic="true"/>
        </textElement>
        <text><![CDATA[Fes Le : ]]></text>
    </staticText>
</band>

and here is how it is displayed for me: Fri Sep 28 09:59:00

My target format is: vendredi 28 septembre 2012 09:59 (in French)

Do you have any idea?

Your question duplicates How to change date format (month name) in iReport? and Setting REPORT_LOCALE in IReport? posts.

• For setting locale in iReport you should call dialog Options - Compilation and exectution (via iReport -> Tools -> Options menu).

For this textField:

<textField pattern="EEEEE dd MMMMM yyyy">
    <reportElement x="0" y="0" width="100" height="20"/>
    <textElement/>
    <textFieldExpression><![CDATA[$F{date}]]></textFieldExpression>
</textField>

The result will be:

Note: It's works only for preview in iReport.

• For Java application you can set JRParameter.REPORT_LOCALE parameter.

Map<String, Object> params = new HashMap<String, Object>(); 
params.put(JRParameter.REPORT_LOCALE, Locale.FRENCH); 
JasperFillManager.fillReportToFile(compiledReportName, params); 

The result will be the same for report generated with code like this.

The working sample, jrxml file:

<?xml version="1.0" encoding="UTF-8"?>
<jasperReport ...  whenNoDataType="AllSectionsNoDetail" ...>
    <parameter name="date" class="java.util.Date" isForPrompting="false">
        <defaultValueExpression><![CDATA[new Date()]]></defaultValueExpression>
    </parameter>
    <title>
        <band height="50">
            <textField pattern="EEEEE dd MMMMM yyyy">
                <reportElement x="200" y="11" width="228" height="20"/>
                <textElement/>
                <textFieldExpression><![CDATA[$P{date}]]></textFieldExpression>
            </textField>
        </band>
    </title>
</jasperReport>

Java code:

Map<String, Object> params = new HashMap<String, Object>();
params.put("date", new Date());
params.put(JRParameter.REPORT_LOCALE, Locale.FRENCH);

JasperReport jasperReport = JasperCompileManager.compileReport(reportSource);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, connection);

JasperExportManager.exportReportToPdfFile(jasperPrint, outputFile);

The result be:
