Yes, the {0} {1}.... {n} construct will work. The ActionMessage class has an
overloaded constructor to handle the substitution.

I use this all over the place - works great. Make sure you "save" the messages
to the request context. You can do the same with errors messages.

Subject: Best way to substitute vars in message resources
I want to frame out messages in Application.properties like this:
err.userexists=The user __UserName__ already exists. Please try again.
What im wondering about is if there is either a built in mechanism in struts to
handle that __UserName__ replacement. Maybe {0} or something? Or should I
just do a manual string replace hack in my controller?
Thanks
