Q. How do I get the latest version of Webwork2 and XWork from CVS?
cvs -d :pserver:guest@cvs.dev.java.net:/cvs login
(Use an empty password, just hit enter..)

Q. How do I build Webwork2/Xwork
Just go into the xwork or webwork directory 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.

Q. How do I set a global resource bundle?
Java class (thanks Drew McAuliffe):
public class WebworkGlobalMessagesListener implements ServletContextListener {
private static Logger log = Logger.getLogger(WebworkGlobalMessagesListener.class);
private static final String DEFAULT_RESOURCE = "global-messages";
/**
* Uses the LocalizedTextUtil to load messages from the global
message bundle.
* @see
javax.servlet.ServletContextListener#contextInitialized(javax.servlet.Servle
tContextEvent)
*/
public void contextInitialized(ServletContextEvent arg0) {
log.info("Loading global messages from " + DEFAULT_RESOURCE);
LocalizedTextUtil.addDefaultResourceBundle(DEFAULT_RESOURCE);
log.info("Global messages loaded.");
}
/**
* @see javax.servlet.ServletContextListener#contextDestroyed(javax.servlet.ServletContextEvent)
*/
public void contextDestroyed(ServletContextEvent arg0) {
// do nothing
}
}
web.xml:
(under listeners section)
<listener> <listener-class>mypackagename.WebworkGlobalMessagesListener</listener-class> </listener>

A: 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):
