and index.xhtml : 

<!doctype html> <html lang="tr"       xmlns:f="http://java.sun.com/jsf/core"       xmlns:h="http://java.sun.com/jsf/html"> <h:head>     <title>title</title> </h:head> <h:body>     <div class="container">         <h:form styleclass="form-signin" prependid="false" id="registirationform">             <h2 class="form-signin-heading">please register!</h2>             <h:inputtext styleclass="input-block-level" value="#{registirationformbean.nickname}" />             <h:inputsecret styleclass="input-block-level" value="#{registirationformbean.password}"/>             <h:commandbutton styleclass="btn btn-large btn-primary" value="register me!" action="#{registirationformbean.registeruser}"/>         </h:form>     </div> </h:body> </html>

edit: server.xml in tomcat

 <connector port="8080" maxhttpheadersize="8192"                maxthreads="150" minsparethreads="25" maxsparethreads="75"                enablelookups="false" redirectport="8443" acceptcount="100"                connectiontimeout="20000" disableuploadtimeout="true"                uriencoding="utf-8"    />

when debug application, in first post see values posted:

but in second time:

use 

<f:view>

and locale.

    <f:view locale="#{registirationformbean.locale}" encoding="utf-8" contenttype="text/html">  <h:head>     <title>title</title> </h:head> <h:body>     <div class="container">         <h:form styleclass="form-signin" prependid="false" id="registirationform">             <h2 class="form-signin-heading">please register!</h2>             <h:inputtext styleclass="input-block-level" value="#{registirationformbean.nickname}" />             <h:inputsecret styleclass="input-block-level" value="#{registirationformbean.password}"/>             <h:commandbutton styleclass="btn btn-large btn-primary" value="register me!" action="#{registirationformbean.registeruser}"/>         </h:form>     </div> </h:body>  </f:view>

provide locale object bean .

public locale getlocale(){ return new locale("tr", "tr"); }
