The Java EE specification includes the JAX-WS API as one of its technologies. JAX-WS is the standard way to develop SOAP (Simple Object Access Protocol) web services in the Java platform and stands for Java API for XML Web Services. JAX-WS is a high-level API; invoking web services via JAX-WS is done via remote procedure calls. JAX-WS is a very natural API for Java developers.

Web services are application programming interfaces that can be invoked remotely. Web services can be invoked from clients written in any language.

Some of the topics we will cover include:

• Developing web services with the JAX-WS API
• Developing web service clients with the JAX-WS API
• Adding attachments to web service calls
• Exposing EJBs as web services
