jsf - Domain based I18N with JSF2.0 -


i have implement i18n based on domain using jsf2.

for example if domain is

www.bookstore.com      --> should go english site www.bookstore.com.cn   --> should go chinese site www.bookstore.co.jp    --> should go japanese site

we have properties files proper translation. when change browser language/locale, able see translated content. don't need behavior actually. setting locale based on domain in filter, seems not working. here code, wrong in code, problem ?

authenticationfilter.java

i have bookstore.properties, bookstore_en.properties, bookstore_en_us.properties, bookstore_zh.properties, bookstore_zh_cn.properties, bookstore_zh_tw.properties, bookstore.properties_ja, bookstore_ja_jp.properties, files in /var/app/conf/ location.

when trying different domains [ have changed host file locally ], when debug filter code, giving correct locale based on domain. don't know why getting english content. if change browser language, can see translated content. wrong in code ?

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
