How to pass REPORT_RESOURCE_BUNDLE to subreports ?

[lilo]

Hi,

To be able to translate my reports, I need to use the REPORT_RESOURCE_BUNDLE parameter to define the translation file to use because I can't put it in the classpath :

Locale locale = new Locale( "fr", "CH" );                        if ( locale != null )            {                FileInputStream fis = null;                try                {                    String filePath = I_ReportCreator.BASE_PATH_FOR_JASPER + getParentFolderPath( report.getFilePath() ) + jasperReport.getResourceBundle() + "_" +locale.toString()+ ".properties";                    fis = new FileInputStream( filePath );                                        ResourceBundle bundle = new PropertyResourceBundle( fis );                    paramName = JRParameter.REPORT_RESOURCE_BUNDLE;                    parameters.put( paramName, bundle );                    parameters.put( JRParameter.REPORT_LOCALE, locale );                }                catch( FileNotFoundException fnfe )                {                    //si le fichier de ressources n'existe pas, on se contente de ne pas l'ajouter                }                finally                {                    if ( fis != null )                        fis.close();                }            }

I works well for simple reports. But not for subreports.

With subreports, jasper ignore the REPORT_RESOURCE_BUNDLE and tries to load the resource file from the classpath. That gives me the error :

20 oct. 2009 17:13:25 net.sf.jasperreports.engine.fill.JRFillSubreport prepareGRAVE: Fill 3945515: exceptionjava.util.MissingResourceException: Can't find bundle for base name i18nreport, locale fr_CH    at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:1521)    at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:1260)    at java.util.ResourceBundle.getBundle(ResourceBundle.java:962)    at net.sf.jasperreports.engine.util.JRResourcesUtil.loadResourceBundle(JRResourcesUtil.java:572)    at net.sf.jasperreports.engine.util.JRResourcesUtil.loadResourceBundle(JRResourcesUtil.java:510)    at net.sf.jasperreports.engine.fill.JRFillDataset.loadResourceBundle(JRFillDataset.java:533)    at net.sf.jasperreports.engine.fill.JRFillDataset.setParameterValues(JRFillDataset.java:568)    at net.sf.jasperreports.engine.fill.JRBaseFiller.setParameters(JRBaseFiller.java:1234)    at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:865)    at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:814)    at net.sf.jasperreports.engine.fill.JRFillSubreport.fillSubreport(JRFillSubreport.java:561)    at net.sf.jasperreports.engine.fill.JRSubreportRunnable.run(JRSubreportRunnable.java:63)    at net.sf.jasperreports.engine.fill.JRThreadSubreportRunner.run(JRThreadSubreportRunner.java:209)    at java.lang.Thread.run(Thread.java:619)

I noticed in JRFillSubreport.evaluateSubreport, jasperreport does the following :

parameterValues =                     getParameterValues(                        filler,                         getParametersMapExpression(),                         getParameters(),                         evaluation,                         false,                         jasperReport.getResourceBundle() != null,//hasResourceBundle                         jasperReport.getFormatFactoryClass() != null//hasFormatFactory                        );

 

Then, in JRFillSubreport.getParameterValues (removeResourceBundle is the paramter corresponding to jasperReport.getResourceBundle() != null)  :

if (removeResourceBundle)            {                parameterValues.remove(JRParameter.REPORT_RESOURCE_BUNDLE);            }

Why does jasperreport remove this parameter for the subreport ?

I tried to manually add

<subreportParameter name="$P{REPORT_RESOURCE_BUNDLE}">                    <subreportParameterExpression><![CDATA[$P{REPORT_RESOURCE_BUNDLE}]]></subreportParameterExpression>                </subreportParameter>

to i18nReport.jrxml and it generated well. But how to do that with iReport ?

I am using jasperreport 3.5.2

Thank you for your help

I made a mistake in adding the parameter for the subreports to the main report. It works well actually.
