Lasse,
Here are the exact words (from RMH's "J2EE Web Services" book) you asked
for. Emphasis is mine. Actually, J2EE 1.4 app servers are
required to support BP 1.0, but this does not preclude J2EE 1.3 app servers to do
so. I just do not know if there any actual instances of such servers.

"This book covers the use of the Web Services APIs as specified in J2EE 1.4
because
version 1.4 is the first Java platform that fully embraces the
Web service paradigm"
"At the heart of J2EE Web Services interoperability, and of Web services
interoperability in general, is the Basic Profile 1.0 (BP), published by
the Web Services Interoperability Organization (WS-I). The BP provides a
set of rules that govern how applications make use of common Web service
technologies so that everyone is speaking the same language. The BP makes
Web service interoperability practical, and coverage of it is a critical
aspect of this book.
Although this book assumes you will want to develop Web services that
comply with WS-I,
only J2EE 1.4 vendors are required to support the BP."
"Throughout this book, particular care is given to framing most discussions
in the context of the Web Services Interoperability Organization's Basic
Profile 1.0. If you have worked with Web service technologies in the past
and have had a chance to study the BP, then you will probably appreciate
why it's so important.
To be completely blunt: I do not believe general
Web service interoperability with anonymous parties is actually feasible
without the guidance of the WS-I Basic Profile 1.0. Experienced Web
service developers can tell you numerous interoperability horror stories
related to the loose language and broad visions defined by standards like
SOAP, WSDL, and UDDI. The WS-I Basic Profile eliminates many, if not all,
of the ambiguities inherent in these primary standards, finally making
interoperability among disparate Web service platforms (.NET, J2EE, Apache
Axis, Perl, etc.) possible."
