Why do you believe you'd have to split the resources? We don't know of a reason that you couldn't use a single resource bundle for string embedded in your GWT code and messages in your DataSource.

Hi, I did all as you said. And I've got DS titles from one of my .properties files. But I can't switch locale. When I change ?locale=... parameter all strings localized in java code like this:

MyMessagesClass cnsts = GWT.create(MyMessagesClass.class);
cnsts.my_localizable_text();

do change locale, but DS titles always remain in same locale (in my case it is ru locale).
As I suppose DS localizations occures once per session and may be it happens before request parameter ?locale=... was read.
How can I select locale at least for the session?

Pass the locale parameter to the .jsp that loads your DataSource definitions and use standard JSTL tags to access locale-specific resource bundles. If you're unfamiliar with JSP/JSTL, there are many tutorials available via Google.

OK, so GWT cannot do it authomatically as GWT.create does.
This code on main jsp page works fine:

<%@ taglib prefix="fmt" uri="/WEB-INF/tld/fmt.tld" %>
<%@ page isELIgnored ="false" %>
<fmt:setLocale value="${param['locale']}" scope="session"/>

thanks
