1 Table of Contents Introduction Audience At Course Completion Prerequisites Certified Professional Exams Student Materials Course Outline Introduction J-410, Deploying Java Web Services introduces the next evolution of Java components: Web Services. It prepares Java programmers to develop Web services and clients according to the Web Services Interoperability (WS-I) Organization's WS-Basic profile, using SOAP 1.1, WSDL 1.1 and XML Schema 1.0. (WS-Basic also calls for UDDI, which has more to do with publishing than development.) Students get an overview of the interoperable and Java-specific Web services architectures, and then learn the standard APIs for SOAP messaging and WSDL-driven, component-based service development. Both document-style and RPCstyle messages and services are covered in depth. For an overview of all of our Java training, visit the Java Curriculum page. You will find descriptions of different skill levels and Java platforms (J2SE, J2EE) you may encounter as a Java Developer. Audience Experienced XML and Java component developers who need to develop and publish web services applications on the Internet. At Course Completion At the end of this course, the student will be able to: Describe how and why Web Services came to be Describe Web Services Architecture Describe the advantages of the Web Services Architecture Describe Web Services Interoperability (WS-I) Use SOAP (Simple Object Access Protocol) Use WSDL (Web Services Definition Language) Use IDL (Interface Definition Language) Build and host a Web Service Generate a simple Web Service Client Use the J2EE Reference Implementation Use the Ant build tool Build Java Web Services Describe the interplay between Web Services and J2EE Use JAXP (Java API for XML Processing) Use JAXB (Java API for XML Binding) Use SAAJ (SOAP with Attachments API for Java

2 Use JAXM (Java API for XML Messaging) Implement a SAAJ/JAXM service Implement a JAX-RPC service (Java API for XML Remote Procedure Call) Describe the Service Life Cycle Declare and use SOAP Namespaces Build SOAP Headers and Envelopes Generate Web Services from Java code (Java-to-WSDL) Generate Java Web Services from WSDL (WSDL-to-Java) Describe Best Practices for Web Services Use EJBs and JSPs with Web Services Describe security threats and solutions for Web Services Prerequisites Before attending this course, students must have: A working knowledge of XML, through either: I-104, XML Quickstart OR I-105, XML Quickstart for Programmers A working knowledge of programming in Java, through either: J-330, Enterprise Java Beans OR J-350, Java2 Enterprise Edition - Accelerated Certified Professional Exams This course will help the student prepare for the following Certified Professional exams: No exam currently exists for this course. For more detailed information about curriculum paths and exams, see the Java Developer Certification pages.
