As is evident from the table even though both WS-I and WSIT working towards
Web services interoperability, there are clear differences between them.
Sun is a current Board Member
of WS-I and has actively participated in the production of Basic Profile
SOAP Binding Profile 1.0,
Security Profile 1.0, Sample Applications
Scenarios and Implementation 1.0,
Attachment Profile Usage Scenario 1.0,
REL Token Profile 1.0,
Token Profile 1.0. As the specifications supported by WSIT are endorsed by
standards bodies in future, WS-I may decide to profile them as well.
The WSIT bits are integrated in GlassFish V2 and comes with a seamless
integration with NetBeans IDE. WSIT is built
as an extension to JAX-WS RI that
provides a Core web services implementation compliant with several of the
profiles mentioned above.
WSIT and JAX-WS are the two key components of
Metro - the Web services stack in GlassFish. That gives you the best of both
world - a product-quality implementation of WS-\* specifications and compliance
with industry-standard profiles.
