Re: [Struts 2.1.8.1] Internationalization: how to remain in the current page ?

[Ulf Liedén <ul...@gmail.com>]

Hi Celinio,

personally, I would build a method that gives back the URL of the page you
are currently visiting, including all parameters. You put this method in a
superclass of all your actions, so that its available everywhere. In the
code you decide which locale parameter to set, according to your current
locale.

The method in the action class could look something like this:

 public String getLocaleSwitchURL() { String url = getContextPath() +
ServletActionContext.getActionMapping().getName() + ".action?" +
"request_locale="; if (getLocale().toString().equals("en_EN")) { url +=
"fr_FR"; flagURL = "fra.jpg"; } else { url += "en_EN"; flagURL = "eng.jpg";
} url += "&"; url += ServletActionContext.getRequest().getQueryString();
return url; } public String getFlagURL() { return getContextPath() +
"images/" + this.flagURL; }
All Strings should of course be configurable, and not hard coded like this.
But just to give you an idea how it could work.  You output the link like
this:

<a href="<s:property value="localeSwitchURL" escape="false"/>">
   <img src="<s:property value="flagURL" escape="false"/>" />
</a>

So if the user clicks the link, he will actually call the same page again,
with the same parameters.

Regards,
Ulf

Hi,
i don't remeber that for sure, but try s:url without action and
namespace, i think it might be what You are looking for.

Best greetings,
