I solved it by adding the locale-string to the parameters of the
servlet-method to be called:
public String getSomething(String param1, long param2, String locale) throws
RemoteServiceException {
ResourceBundle rb = getResourceBundle(locale);
try{
doSomething()
}
catch(Exception e){
throw new
RemoteServiceException(rb.getString("ServiceGeneral_Error_SomethingHappened"));
}
}
public static ResourceBundle getResourceBundle(String locale) {
Locale loc = getLocale(locale);
ResourceBundle rb =
Utf8ResourceBundle.getBundle(AdminToolsI18NConstants.class.getName(), loc,
AdminToolsI18NConstants.class.getClassLoader());
return rb;
}
public static Locale getLocale(String locale){
if (locale == null){
return null;
}
StringTokenizer tt = new StringTokenizer (locale, "_");
Locale loc = new Locale(tt.nextToken(), tt.hasMoreTokens() ? tt.nextToken() :
"", tt.hasMoreTokens() ? tt.nextToken() : "");
return loc;
}
The Utf8ResourceBundle is inspired by

That way you can use the ResourceBundle-files you created for the
GWT-client. In each bundle I added one property, e.g.
Locale = DE
So a call in the GWT-client looks like this:
public static final MyI18NConstants CONSTANTS = (MyI18NConstants)
GWT.create(MyI18NConstants.class);
[...]
GeneralServices.Util.getInstance().getSomething(param1, param2,
CONSTANTS.Locale(), new AsyncCallback(){
[...]
public void onFailure(Throwable caught) {
Window.alert(caught.getMessage());
}
};
If you have defined Messages instead of Constants you can do the filling
of the parameters by a simple text-replacement, e.g. by replaceAll:
rb.getString(...).replaceAll("\{0\}", e.getMessage());
