Following code worked for me:
import oracle.javatools.resourcebundle.BundleFactory;
import java.util.ResourceBundle;
* This method retrieves localized strings from a given XLIF resource bundle.
* @param bundleName The XLIF bundle from which the localized string is to be retrieved.
* @param key The key of the localized string.
* @return The localized string retrieved from the given XLIF bundle.
public static String getXlifLocalizedString(String bundleName, String key) {
if (StringUtils.isEmpty(key)) {
return key;
if (StringUtils.isEmpty(bundleName)) {
return "[" + key + "]";
String localizedString = null;
ResourceBundle resourceBundle = null;
try {
resourceBundle = BundleFactory.getBundle(bundleName);
localizedString = resourceBundle.getString(key);
} catch (Exception e) {
LOG.log(Level.SEVERE, "Problem in loading XLIF resource bundle: " + bundleName, e);
return "[" + key + "]";
return localizedString;
}
