I am using Struts2 Internationalization to support English & Arabic.

I want to know that is it possible to dynamically or automatically change the position of label which comes before any input (text, date, etc.) when the locale changes?

E.g.

LTR -> English -> First Name – “Input Text Box”

RTL -> Arabic -> “Input Text Box” – أول اسم

Any possible solution for this?

    Either (ab)use java.awt.ComponentOrientation

    String direction = ComponentOrientation.getOrientation(locale).isLeftToRight() ? "ltr" : "rtl";

    (its source code is pretty trivial though, there are only 4 languages which are RTL, here’s an extract of relevance)

    public static ComponentOrientation getOrientation(Locale locale) {
    String lang = locale.getLanguage();
    if ("iw".equals(lang) || "ar".equals(lang) || "fa".equals(lang) || "ur".equals(lang)) {
        return RIGHT_TO_LEFT;
    } else {
        return LEFT_TO_RIGHT;
    }
}

    Or put it in a recourcebundle yourself.

    this.direction = ltr

    And read it as follows

    String direction = bundle.getString("this.direction");

    Either way, you can make use of this to change the direction accordingly.

    <html dir="${direction}">

    which would end up as <html dir="ltr"> or <html dir="rtl"> in generated HTML.
