Good evening to every one, I am Facing serious problem with base resource bundle error. I have to translate the report as per requirement from one language to another by choosing locale. So I have created a properties file for each language such as xxxx_de_DE, xxxx_en_US.. etc .. I have place this files along with my jasper files in a location. My report is running fine while I am running from iReport3.1.. but when I try to run through my java application its gives the following error.. java.util.MissingResourceException: Can't find bundle for base name invoice_header_backup, locale en_US at java.util.ResourceBundle.throwMissingResourceException(ResourceBundle.java:837) at java.util.ResourceBundle.getBundleImpl(ResourceBundle.java:727) at java.util.ResourceBundle.getBundle(ResourceBundle.java:700) 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:527). i have tried a lot more over this issue.. but I can’t able overcome this problem.. any please suggest me.. how to overcome this problem.. thanks in advance…
