Using a Java Filter to change locale not working -

-

i'm trying change locale using java filter following code not work jsp page still rendered in english:

public class preferencefilter implements filter {      public void dofilter(servletrequest request, servletresponse response, filterchain chain)         throws ioexception, servletexception {          httpservletrequest req = (httpservletrequest) request;         httpservletresponse res = (httpservletresponse) response;          locale locale = stringutils.parselocalestring("fr");           res.setlocale(locale);         chain.dofilter(req, res);     } }

i using spring mvc , using own translation system translations different locales:

<bean id="messagesource"     class="com.mycompany.web.translations.databasedrivenmessagesourceimpl" scope="singleton">     <property name="cacheseconds" value="3"/>     <property name="defaultencoding" value="utf-8"/> </bean>

if you're using jstl internationalize jsps, it's normal: jstl doesn't locale response, configured scoped parameter or, if no locale set, request.

use 

config.set(request, config.fmt_locale, locale);

where config class javax.servlet.jsp.jstl.core.config..

how copy observablecollection item observablecollection without reference of first collection? here observablecollection item value changes affecting both collections. code private observablecollection<ratemodel> _allmetalrate = new observablecollection<ratemodel>(); private observablecollection<ratemodel> _metalrateondate = new observablecollection<ratemodel>(); public observablecollection<ratemodel> allmetalrate { { return this._allmetalrate; } set { this._allmetalrate = value; notifypropertychanged("metalrate"); } } public observablecollection<ratemodel> metalrateondate { { return this._metalrateondate; } set { this._metalrateondate = value; notifypropertychanged("metalrateondate"); } } foreach (var item in metalrateondate) allmetalrate.add(item); what causing , how can solve it? you need clone object referenced item before it's a...

All overlapping substrings matching a java regex -

-
is there api method returns (possibly overlapping) substrings match regular expression? for example, have text string: string t = 04/31 412-555-1235; , , have pattern: pattern p = new pattern("\\d\\d+"); matches strings of 2 or more characters. the matches are: 04, 31, 412, 555, 1235. how overlapping matches? i want code return: 04, 31, 41, 412, 12, 55, 555, 55, 12, 123, 1235, 23, 235, 35. theoretically should possible -- there obvious o(n^2) algorithm enumerates , checks substrings against pattern. edit rather enumerating substrings, safer use region(int start, int end) method in matcher . checking pattern against separate, extracted substring might change result of match (e.g. if there non-capturing group or word boundary check @ start/end of pattern). edit 2 actually, it's unclear whether region() expect zero-width matches. specification vague, , experiments yield disappointing results. for example: string line = "xx90xx"; strin...
