Orbeon Form Localization Using Current Site's Session Language

I'm using ORBEON 2018.2.3.201905172253 PE within SAP Commerce (Hybris). From Orbeon documentation and the tests I've run, I understand forms localization works through a language d

Solution 1:

You can extend de.hybris.platform.xyformsservices.proxy.impl.DefaultProxyService rewriteURL method and pass Orbeon the user language, something like this:

URIBuilder builder = null;
        try
        {
            builder = new URIBuilder(this.orbeonAddress + path);
        }
        catch (final URISyntaxException e)
        {
            LOG.error("Error occurred while building the URL : " + e);
            throw new MalformedURLException(e.getMessage());
        }

        // if the original URl had a QueryString...
        builder.setQuery(u.getQuery());

        // If the form should be embeddable
        if (embeddable)
        {
            builder.addParameter("orbeon-embeddable", "true");
            builder.addParameter("fr-language", getCommonI18NService().getCurrentLanguage().getIsocode());
        }

        final String newURL = builder.toString();

        LOG.debug("Rewritten URL [" + newURL + "]");
        return newURL;

Hope it helps
