If we use the above approach to provid II8N Support then every time user has to specify lang country, it is not suggestible in web applications.

To overcome the above problems, we have to provide I18N Support with out depending on the user, by getting client browser provided language setup

When we submit a request from a client browser then browser provided lang will be send to server in the from at “accept lang” request header, here it we get “accept-language” request header value then it is possible to identify from which local the request is coming, with this, we are able to provide I18N Support without specifying lang & country by the user

To get a particular request header value, we have to use the following method from servlet request, public string get header (String header-name)

Public class I18N Servlet extends Http servlet{ = IL; Protected void do Get(Http Servlet Request request, Http Servlef Response response) Throws servlet Exception, Ioexception{

Try{

String locate=request. get header(“accept-language”);

String Tokenizer st= new string tokenizer(local, “-”);

Int count= st. count tokens();

Local i=null;

If (count==1){

String long=st.next token();

I=new locale (c lang);

{

If(count==2){

String lang=st. next token();

String country=st. next token();

I=new locale (c lang, country);

}

If(count==3){

String lang=st. next token();

String country=st. next token();

String sys-var=st. next token();

I=new locale (lang, country), sys-var);

}

Number Format nt=number formal, get Insurance(l);
