Jean-Sebastien Delfino commented on TUSCANY-1989:
-------------------------------------------------
The WAR built from sources by running ant run in the calculator-webapp module
works so it's a problem with the pre-built WAR shipped in the distro.
I suspect there'll be a problem with a WAR built from sources using Maven as
well, as it's how the prebuilt WAR was built.
