Course Number: JAVA.064 Duration: 5 days (full-day sessions) OR Weekend/Evening sessions Training Overview: This course will give you a thorough understanding and solid hands-on experience of the current Web services architecture, state of the art in developing interoperable web services on the Java EE platform and the technologies that support Web services such as JAX-WS, JSR-181, SOAP, WSDL, and the WS-I Basic Profile. JAX-WS is central to the course, and we cover both WSDL-driven and Java-driven development paths, as well as message handlers and attachment support. With the new Provider and Dispatch APIs, it's now much easier to integrate SAAJ, JAXB, and JAXP code into services and clients, and we explore these strategies in depth as well. This course will also review SOA (Service Oriented Architecture) and BPEL (Business Process Execution Language) as applicable to the industry applications using Web Services. Location and Pricing: Most of our courses are conducted online OR at our training facility and are customized to meet our students needs. We also provide customized onsite training at our clients' locations. Pricing for an online course depends on if its a weekend/evening course or a full day course. The weekend/evening courses are most cost-effective as they are spread over a period of weeks giving you ample time to complete the hands-on exercises. To receive a customized proposal that will fit your schedule and price quote, please contact us  Training Prerequisites: All attendees must be experienced Java developers with hands-on grasp of object-oriented principles. Prior Java EE development experience is recommended but not required. Attendees must be able to read XML documents and to write well-formed XML by hand. Training format: This class is 60% lecture, 40% hand on with one-on-one dedicated time-slots with the instructor. Training Materials: All students receive a copy of related courseware / material. Software Needed on Each Student PC: Any operating system that supports Java 1.5.0 or later Java SE SDK 1.5, 1.6, or later Java IDE of your choice (We will advise on specific versions of the software required based on your standard development and production environments.) Additional software - please contact us for a detailed setup sheet Training Objectives: Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL. Build JAX-WS services and clients that take full advantage of the automated data binding of JAXB. Understand the importance of the WS-I Basic Profile for interoperable web services. Use lower-level SOAP and XML APIs for services and/or clients. Customize data binding by specifying specific type mappings or altering method or parameter names. Expose session beans as web services. Incorporate binary data, such as images, into service and client code.
