Ah, sorry, didn't see that it was a converter. What it sounds like you're asking is how to use a file other than "messages.properties"in JSF. Are you using the default bundle or not Because here you're not even telling JSF about "MyBundle". You're still using "messages". <application> | <locale-config> | <default-locale>de</default-locale> | <supported-locale>de</supported-locale> | <supported-locale>en</supported-locale> | <supported-locale>fr</supported-locale> | </locale-config> | <message-bundle>messages</message-bundle> | </application> Where does the converter live by the way (.ear or .war)? I had a problem getting a TabChangeListener to work when it was in the EJB context. View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4037647#...
