Since these two specs are already in GlassFish/SJS AS 9.0,
installing JWSDP 2.0 on these containers does not provide any improvements on that front,
but, they do add support for JAX-WSA, and in a future version they will provide more
I checked with Ramesh and he confirmed that the
JWSDP 2.0 samples work on GlassFish.
BTW, Ramesh's blog describes a problem with a later, EA3, release of JAX-WS 2.0,
Ray's blog on the resolution.
