Programming SOAP Web Services With JAX-WS

Course: SOAPWS

Duration: 5 Days

Level: II

Course Summary

This course will teach students how to develop SOAP Web Service provider and consumer applications for the WebSphere Application Server 8.0 platform. It will explain the theory behind XML schema, WSDL and SOAP. It will also teach students various Java specifications that cover Web Services development (such as JAX-WS and JAXB).

Advanced topics such as WS-Security, WS-Addressing, WS-ReliableMessaging and WS-Trust are also covered.
