It seems firstly ${placeholder} is evaluated to empty by Struts then '' is
evaluated to ' by MessageFormat.

I guess '$'{placeholder} or $'{placeholder}' or '$''{placeholder}' should work
:\ could you please report back the result for each one? And which Struts
version you test?
Thanks for using Struts!
