specifications. Conveniently, several open source implementations of this specifica-
tion are available.
With a small amount of effort, and no changes to your core application at all,
you've seen that you can successfully add a remote service to your application. At no
point in this chapter did you have to deviate from a standard, and the only piece of
customization you did was to specify
CXF
and
SCA
configuration types in your end-
point definitions.
Although the Remote Services Specification is a straightforward way of remoting
OSG
i services, its scope is restricted to relatively homogeneous
OSG
i-only systems. In
our experience, heterogeneous environments, with a mix of new and old compo-
nents, and
OSG
i components and non-
OSG
i components, are more common.
Although it works as a remote services implementation, one of
SCA
's real strengths is
the flexibility of its bindings and component types, which allow a wide range of differ-
ent types of systems to be knit together into a harmonious unified architecture. We'll
discuss strategies for integrating heterogeneous systems, as well as how to migrate leg-
acy applications to an
OSG
i-based platform, in the next chapter.
