You need to configure your message resources through the struts-config.xml - init parameters in the web.xml don't work in Struts 1.2
http://struts.apache.org/userGuide/configuration.html#resources_config So in your case you need something like the following in your struts-config.xml.... <message-resources parameter="..." factory="org.example.MyMessageResourceFactory " /> You can use the "parameter" element for any configuration value you want - thats the argument passed to the factory's createResources() method. I believe you can also use <set-property> elements for other config values - although I've never actually tried it out.
