Rapid CORBA Server Development in Tcl: A Case Study
Jason Brazile and Andrej Vckovski, Netcetera AG, Zurich, Switzerland
Abstract
A large Swiss bank needed to collect, combine, process, and distribute
financial market data from various 3rd party data sources to a large
number of internal and external clients -- the typical integration task
at which scripting languages excel. The bank uses an implementation of
CORBA as their standard enterprise-wide middleware for distributed
applications. We describe how we designed and built a Tcl/C++ transport
framework which allowed us to develop the "kernel" of this server
application entirely in Tcl, yet support CORBA as the primary interface
to the server. We further describe how this framework allows a small
development team to rapidly implement changes and enhancements to the
server and its external interface, while automatically generating the
corresponding changes that are needed for the CORBA interface.
Additionally, we show how we were able to automatically generate code
to create new tcl commands that make use of the same, generated,
Tcl/C++ marshalling routines in order to develop a CORBA client in Tcl,
which is used to regression test the server, when full end-to-end
testing is needed.
