Initiatives such as ebXML, UDDI and the Java API for XML Messaging (JAXM) promise to have a significant impact on how organizations will conduct electronic business in the near future. ebXML and UDDI aim to specify a platform- and vendor-neutral XML-based frameworks for discovering potential business partners and conducting eBusiness transactions, while JAXM offers a Java API for packaging and transporting e-business messages based upon such frameworks. This session will provide an overview of the emerging specifications that will enable an open, standards-based electronic market, and the impact that these initiatives will have upon Java developers. We will also discuss the relationship between these e-business standards and XML transport protocols such as SOAP and the new W3C XML Protocol.
