The Web Services Resource Framework (WSRF) has
redefined grid computing standards, making Web
services more suitable for grid applications by adding
persistent state management. However, it is still
difficult to build, deploy, and evolve such services,
since different Web and grid services containers
require that the services they host be written in specific
languages, to target particular internal interfaces for
state management. Therefore, services must be built
and deployed differently for each hosting environment.
This paper describes uniform dynamic service code
deployment on three Web services containers (namely,
Tomcat, ASP.NET and a gSOAP based C++
container), and two grid services containers (namely,
GT4 and WSRF.NET). Containers receive the code in
an XML-based standard intermediate form, and then
generate container-specific native code in different
languages, without exposing these details to
applications and grid services programmers. The
dynamically deployed code can access state managed
by the hosting container, can utilize functionalities
exposed by statically deployed services, and can
communicate with other dynamically deployed
modules, running either in the same container or in
different containers. A performance study shows that
the newly deployed mobile code can run nearly as
efficiently as it would if it had been deployed statically,
through container-specific mechanisms.
