There is no inbuilt thing as such in struts for doing that .but you always have an option of placing the same key and value in the ApplicationResources.properties and then read it using the bean:message tag .but it all depends on where you need to place that resource
For example in a web application ,I can have the property file ApplicationResources.properties in which I can have the pair,page.title=Home,which I can retrieve in my .jsp as <bean:message key="page.title"/>. But for this,I should have the entry <message-resources parameter="ApplicationResources" /> in my struts-config.xml.
