Web Services in VA Smalltalk: Enhancements for 8.0, Overview of Deployment Strategies and Debugging Tips
Diane Engles, Sr. Software Developer, Instantiations

The Web Services framework has been extended to accommodate the document/literal wrapped style of wsdl. Diane presents a complete example that contrasts the differences in processing between document/literal and document/literal wrapped. She also discusses how to deploy wsdl with and without using a deployment descriptor, and points out good places to set breakpoints along the way to assist in debugging problems.

Implementing Genetic Algorithms Efficiently in Smalltalk
Bob Whitefield, ModelDesign Corporation

Mendel is a genetic algorithm framework written in VA Smalltalk. Genetic algorithms and evolutionary computation use principles from nature to solve difficult optimization, search, and pattern recognition problems. Mendel simplifies the use of genetic algorithms, allowing this powerful technique to be easily applied to a wide variety of problems. A version of Mendel is used by a major agricultural supplier to optimize truck tours, saving nearly a half-million dollars on transportation costs in the first year. This talk gives a brief overview of evolutionary computation, describes Mendel and how it was implemented in VA Smalltalk, and shows several examples of it in action.

Gaining Object Persistence
Martin McClure, Software Architect, Gemstone

Many VA Smalltalk applications use a relational database for persistence. However, it is often simpler to just store the Smalltalk objects themselves. The combination of VA Smalltalk and GemStone/S makes this possible. In this presentation, Martin demonstrates the process of connecting a VA Smalltalk application to GemStone, and discusses the issues involved.
