Q. How do I decouple XWork LocalizedTextUtil global resource bundle loading from serlvets (ServletContextListener)?
A. If you're using XWork outside a Web context, then use whatever startup hooks you have in that context (i.e. application start for a desktop app) to add the global resource bundle. This is a startup activity, so use whatever mechanisms are provided in the context you're running in.

Q. How do I add I18N to a WW2 TagUI tag, like ww:textfield?

<ww:textfield label="'i18n.label'" name="'label1'" value="''">

A. This will get the localized text message for the key "i18n.label" and put it in the label.

<ww:textfield label="getText('i18n.label')" name="'label1'" value="''">

Alternatively, you could modify controlheader.vm and copy it to /template/xhtml. There you could make it so that it automatically does a call to $stack.findValue("getText($parameters.label)"), making the first example actually work for i18n.

Q: Can I add I18N outside the Action's context? i.e. adding i18n to some JSP using the ww taglib?
Yes, use the <ww:i18n> tag to push a resource bundle on to the stack. Now calls with <ww:text/> or <ww:property value="getText(...)"/> will read from that resource bundle.
