localization - Loading of Java message properties for internalization -

-

i have following java i18n message class.:

public class messages {       private static final string bundle_name = "languages.message";     private static final resourcebundle resource_bundle = resourcebundle.getbundle(bundle_name);      private messages() {     }      public static string geti18n(string key) {         try {             return resource_bundle.getstring(key);         } catch (missingresourceexception e) {             return '!' + key + '!';         }     }      public static string geti18n(string key, object... params  ) {         try {             return messageformat.format(resource_bundle.getstring(key), params);         } catch (missingresourceexception e) {             return '!' + key + '!';         }     } }

i have created following message properties files.:

message.properties message_de.properties message_de_de.properties

in program translation according default locale of system. if de_de, german message properties message_de_de.properties loaded.

if default locale de_ch, there no message properties file. message_de.properties fallback loaded or need implement myself?

according this blog post right.

so when default locale of system de_de , request resource locale en_us, lookup order properties files is:

  1. myapp_en_us.properties
  2. myapp_en.properties
  3. myapp_de_de.properties
  4. myapp_de.properties
  5. myapp.properties

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens ...
