How do I get the latest version of Webwork and XWork from CVS?
cvs -d :pserver:guest@cvs.dev.java.net:/cvs login
(Use an empty password, just hit enter..)
cvs -d :pserver:guest@cvs.dev.java.net:/cvs checkout webwork
cvs -d :pserver:guest@cvs.dev.java.net:/cvs checkout xwork

Note: WebWork from the CVS does not compile with the latest 1.5 J2sdk. Use the stable J2sdk 1.4.2.

How do I build the latest versions XWork and Webwork?
Just go into the XWork or WebWork directories and run 'ant' (you must have ant installed and have the jars of junit and clover inside $ANT_HOME/lib)

Once you have built the xwork.jar copy it into the webwork/lib/core folder, and delete the old one.

You need to create a message for that field, for example if you have a user.dob field you would use this in your messages file (see above for example on setting a global messages file):
invalid.fieldvalue.user.dob=Please enter Date of Birth in the correct format.

How can I use the IOC container to initialize a component in another object that isnt an action?
Obtain the ComponentManager from the request: ComponentManager cm = (ComponentManager) ServletActionContext.getRequest().getAttribute("DefaultComponentManager");
then you need to initialize it using: cm.initializeObject(Object)

How do I decouple XWork LocalizedTextUtil global resource bundle loading from serlvets (ServletContextListener)?
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.

How do I add I18N to a UI tag, like ww:textfield?

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

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.
