This article has discussed HTTP's stateless nature and how Web Services can be implemented by using vendor-specific and standard JAX-RPC interfaces to gain access to Web Service context and HTTP Session under which the user operates. The context enables developers to implement advanced domain services with several features such as personalization, versioning, security, mediation, and so on. However, developers should take due diligence before using any vendor-specific interfaces because they will put them in vendor lock-ins and perhaps cause inherent migration problems in the future.
