It is possible to localize or modify the message files shipped with the Cúram SDEJ. These message files are located in the message directory of the SDEJ and are in the same format as Cúram application message files but with the extension .iml.
The msggen target, when run, will merge the localized .iml message file with the original one located in the SDEJ. The localized message file will have the higher precedence order. It will then generate the properties files only and include them in the messages.jar file created. The messages.jar file will always be on the classpath before the default SDEJ messages in a runtime application.
