In-Depth Information
Extensive support for XML is a core component of Java EE.
Support for both document-based and stream-based parsing of
XML
documents
forms
the
foundation
of
XML
support.
Additional
APIs
provide
XML
registry
service,
remote
procedure
call
invocation
via
XML,
and
XML-based
messaging support.
Web services, which rely heavily on XML, provide support
for
describing,
registering,
finding,
and
invoking
object
services
over
the
Web.
Java
EE
provides
support
for
publishing
and
accessing
Java
EE
components
as
web
services.
Transaction support is required in order to ensure data
integrity for distributed database systems. This allows
complex, multiple-step updates to databases to be treated as a
single step with provisions to make the entire process
committed upon success or completely undone by rolling
back on a failure. Java EE provides intrinsic support for
distributed database transactions.
Java
EE
provides
configurable
security
to
ensure
that
sensitive
systems
are
afforded
appropriate
protection.
Security
is
provided
in
the
form
of
authentication
and
authorization.
