The e-Market Integrator is a business to business (b2b) application designed to assists in the process of supply chain management. This is a J2EE application, which makes use of the evolving Web services standards to create an application, which integrates different system and allows them to work cooperatively to perform a product search. The technique discussed here resembles a b2c-shopping portal where Internet surfers key in a product name (which they are looking for); the site returns product details from many different online retailers. The major difference in this case is that even the customer end is going to be an automated process and data has to be exchanged in a format, which is machine understandable. This is a prototype application, which aims to prove how J2EE along with new open source libraries and web sphere technology can be used to develop and deploy a solution to such a problem.
