Is it possible with jasper Reports
to load a ResourceBundle
(for i18n
) at runtime?
I want to create a report from a jrxml file (for example c:\\reports\\report.jrxml
)
with my labels in the properties file located at ( c:\\messages\\report.properties
).
I only found example where the property file is in the classloader.
Thanks
John Ferguson's blog mentions that the trick is to override the REPORT_RESOURCE_BUNDLE
parameter with a custom ResourceBundle instance.
// Compiling the report is not a necessary step; prefer using .jasper files
// that have been pre-compiled to avoid this compilation step.
//
JasperDesign jasperDesign = JasperManager.loadXmlDesign("Report.jrxml");
JasperReport jasperReport = JasperManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("REPORT_LOCALE",LocaleManager.currentLocale());
parameters.put("REPORT_RESOURCE_BUNDLE",resourceBundle);
Connection conn = DBConnectionFactory.getConnection();
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,
parameters,
conn);
The resourceBundle
can come from anywhere. For example:
try(FileInputStream fis = new FileInputStream("/tmp/report.properties")) {
ResourceBundle resourceBundle = new PropertyResourceBundle(fis);
// Pass resourceBundle into the report, as shown above.
}
loading bundle from resources package:
ResourceBundle bundle=ResourceBundle.getBundle("/reports/bundles/bundle",Locale.CANADA_FRENCH);
filling report::
params.put("REPORT_RESOURCE_BUNDLE", bundle);
JasperPrint jasPrint = JasperFillManager.fillReport(reportStream, params, data);
