Course Overview
The Java Web Services course by Open Source is designed to equip developers with the skills needed to build, deploy, and secure modern web services using industry-standard Jakarta EE technologies. This training prepares learners for advanced development roles such as Java Developer, Backend Engineer, and Integration Specialist, focusing on real-world implementation of both SOAP and RESTful services. With over 70% of enterprise systems still relying on Java-based backend architectures, expertise in Java Web Services remains a high-demand skill across financial, healthcare, and telecommunications sectors. The curriculum aligns with current Jakarta EE specifications, ensuring developers are proficient in building scalable, interoperable web services that meet modern integration requirements.
Students engage with core technologies including Jakarta XML Web Services (JAX-WS), Jakarta RESTful Web Services (JAX-RS), Project Jersey, JAXB for XML/JSON binding, WSDL, and WS-Security. Through hands-on labs conducted in a standard Java IDE environment such as NetBeans or IntelliJ IDEA, participants build functional web services from the ground up—creating SOAP endpoints with JAX-WS, developing REST APIs using JAX-RS annotations, securing services with OAuth and WS-Security policies, and consuming external services via client implementations. A key project involves designing a fully integrated RESTful service for a simulated e-commerce platform, where students implement resource classes, configure media type handling, apply exception mapping, and test end-to-end functionality using HTTP clients.
This course provides direct preparation for professional-level Java development credentials recognized across enterprise environments, particularly those requiring compliance with Jakarta EE standards. Certified Java Web Services developers earn an average salary of $84,388 in the U.S., with mid-level roles in cities like Austin reaching over $100,000 annually. Koenig Solutions enhances learning outcomes with Guaranteed-to-Run batches and access to official courseware, enabling learners to master complex integration scenarios through expert-led, practical instruction. Completing this training empowers developers to advance into cloud integration, microservices architecture, and full-stack engineering roles with confidence in their ability to design robust, standards-compliant web services.
