Java APIs for XML-based RPC

Course Description:

'' This module teaches students how to develop Web services using SOAP, WSDL, and Java, with the help of the Java API for XML-Based RPC, or JAX-RPC. JAX-RPC abstracts almost all the details of SOAP messaging using WSDL as a description language for interface and implementation; this allows the Java developer to concentrate on application and service specifics. (In this way JAX-RPC is analogous to Java RMI and the EJB architecture, and SOAP/HTTP is treated as nothing more or less than an RPC transport protocol.) JAX-RPC specifies service development either from WSDL documents as a starting point or beginning with Java code and generating the WSDL for client use; this module addresses both possible development paths and analyzes their relative advantages.



Intended Audience:

Programmers who need to develop web services using SOAP, WSDL, and Java, with the help of the Java API for XML-Based RPC, or JAX-RPC.



Prerequisites:

Experience in Java Programming, including object-oriented Java and the Java streams model, is required. Introduction to Java is recommended.



Some understanding of the Web services architecture, including the role of SOAP in Web-service messaging, will be helpful. Overview of Web Services is recommended.



Some understanding of XML and XML Schema will be helpful, but is not strictly necessary. XML Fundamentals is recommended.



Student Responsibilities:

Students should share the same general level of knowledge and experience. If a participant does not demonstrate these, the CITI instructor will take the necessary steps either to prepare the participant or place him/her in a more appropriate course. This policy is intended to maintain the high level of quality control that you have come to expect from CITI.
