Can you try one of the recent GlassFish V2 builds?
In GlassFish V2, we've simplified the default-web-module mechanism
quite a bit.
In GlassFish V1 and earlier SJSAS versions, we used to treat "/" and
"/webapp" (where "webapp" has been designated as the virtual-server's
default-web-module) as separate web modules, which was inefficient
and resulted in unnecessary code complexity. Under the covers, the
container would create a copy of "/webapp" and deploy it at "/".
In GlassFish V2, we no longer duplicate "/webapp" at "/". Instead, we make
the *same* copy of "webapp" available at both "/webapp" and "/".
