I was looking at a way for a GWT application to use the Browser's
language preference without having to either provide the parameter
(locale=fr) on the URL or to add the metatag for the locale in the
HTML.
The solution is quite easy to implement as long as the GWT application
is running within a Servlet container (e.g. Jetty, Tomcat).
The first step is to have the GWT application localized for the
language you want to use. I will not explain how to do that since the
documentation of GWT is quite clear.
The second step is to create a JSP from the HTML, i.e. copy the HTML
as JSP.
For example: copy TestLocale.html to TestLocale.jsp
You add the following lines at top of the JSP:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"
import="java.util.Locale" %>
You add the following metatag within the head tag of the html
contained in the JSP
<meta name="gwt:property" content="locale=<%=request.getLocale()
%>">
The third step is to replace html by jsp in the <welcome-file> tag
within web.xml:
For example:
<welcome-file-list>
<welcome-file>TestLocale.html</welcome-file>
</welcome-file-list>
become
<welcome-file-list>
<welcome-file>TestLocale.jsp</welcome-file>
</welcome-file-list>
The fourth step .. testing by replacing html by jsp in the URL.
I have an Eclipse project where I internalionalized (English and
French) the default GWT project created by the Eclipse plugin. I
could share the project if required.
You are free to incorporate my humble contribution in the GWT
documentation unless there is something wrong with it, in which case I
would like to know what.
