Resolving Struts properties

I've looked through the forum and help and seen some references to this, but I can't find anything explicit.

I have a Struts application which, as is standard, stores its properties in ApplicationResources.properties. These properties are accessed throughout the JSP files. For example:

<bean:message key="errors.header"/>

The key values (in this case, errors.header) is being highlighted red as an error. The only reference I can find in the help is in "Property File Editing," which says:

You need to use the following code:
public class XXX {
void f(){
String newpropvalue = PropertyResourceBundle.getBundle("myBundle").getString("newprop");
}
}

Of course, in Struts, I never explicitly load the properties file. How can I get rid of the sea of red ink in my JSP files? Is there a way to make IJ understand where the properties are supposed to be coming from?

This is on W2K SP4 with Irida build 3429.

Thanks!
