This hands-on course introduces Web Services and open industry standards such as SOAP, UDDI, and WSDL. On the course, participants will learn to add powerful Web Services capabilities to their Java and J2EE applications, including web services for Enterprise Java Beans. Participants will write simple Java Web Services for Apache Axis and use the Eclipse platform and Oracle JDeveloper 10g to develop, debug, and deploy J2EE Web services to two different J2EE web containers (Apache Tomcat and OC4J).
