date format - Java DateFormat issue on Mac vs Windows -

-

i using code below on mac osx 10.10.2 , it's behaving strangely.

import java.text.dateformat; import java.text.simpledateformat; import java.util.date;  public class stringtodate {      public static void main(string[] args) throws exception {         string dateinstring = "23/oct/2015";         dateformat formatter = new simpledateformat("dd/mmm/yyyy");         date date = formatter.parse(dateinstring);         system.out.println(date);     } }

output on mac:         sun dec 28 00:00:00 cst 2014

output on windows: fri oct 23 00:00:00 cdt 2015

why mac output wrong?

y week year. use y year.

dateformat formatter = new simpledateformat("dd/mmm/yyyy");

also, make sure dateformat's locale right one.

edit:

a date has millisecond precision, if want nanosecond precision, shouldn't use date , simpledateformat.

s milliseconds. since tell simpledateformat last part of string milliseconds, parses that: 545000000 milliseconds (i.e. bit more 6 days, explains difference between input , output).

to accurate result, millisecond, remove last 6 characters of string, , use pattern "dd-mmm-yyyy-hh.mm.ss.sss".

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 ...
