Java Web Services Training Overview
Web Services are designed to allow web-based access to distributed software and business services using standard protocols such as HTTP and standard XML formats. This SOA and Java Web Services (JAX-WS) training course gives attendees a thorough understanding of current Web Services architecture and teaches them how to use supporting technologies including the new Java APIs such as JAX-WS and JSR-181.
