The URL tag isn't meant to be used with a query string. The best way to write

<s:url action="Welcome">

Well, since "en" is a constant, and not a stack reference, it needs to
be quoted or parametized itself.
Here's three idioms that work:
<h3>Language Options</h3>
<ul>
<li>
<s:url id="en" action="Welcome">
<s:param name="request_locale">en</s:param>
</s:url>
<s:a href="%{en}">English</s:a>
</li>
<li>
<a href="<s:url action="Welcome">
<s:param name="request_locale" value="'ru'"/>
</s:url>">Russian</a>
</li>
<li>
<a href="<s:url value="Welcome.do">
<s:param name="request_locale" value="'ja'" />
</s:url>">Japanese</a>
</li>
</ul>
I believe the first form ("en") is preferred, the second is OK, and
the third ("ja") would be considered sub-nominal practice, since it
embeds the extension in the URL (which could be changed in the
configuration).
We use the third form a few times in the Showcase, and I'll make a
point to replace them with preferred forms before the next snapshot.
I think I might want to add a "taglib examples" module to the
Showcase, that just demonstrated the preferred idioms straight-up,
something like what we have for Struts 1, but just as a usage key,
rather than a testing device.
