Resolution:

To resolve this error, first add a message resources bundle (a .properties file) to the Struts-enabled web application - the file should be placed in the classpath of the application.

Next, configure the file information in the struts-config.xml Struts configuration file, by adding the <message-resources> element as below,

<message-resources parameter="resources.ApplicationResources" />

where resources.ApplicationResources is the fully-qualified name (reflecting the package structure) of the file ApplicationResources.properties (the .properties extension is not required in the configuration).
