TT7301 Core SOA Web Services - J2EE

  1. 1. Learning Solutions Information Worker Solutions TT7301 Core Web Services and SOA for J2EE Developers (4 days) Duration: 4 days Skill Level: Intermediate Focus: J2EE Web Services Audience: Experienced J2EE developers Format: Extensive hands-on programming labs, expert lecture combined with open discussions and high-Level demonstrations and dynamic group exercises. Language / Tools: Java/ XML, SOAP, REST, WSDL /Delivered with most IDEs, including Eclipse, MyEclipse, RAD, JDeveloper, etc. and many servers, including JBoss, WebSphere, WebLogic, etc. Delivery Format: Available for onsite private classroom presentation, or live online / virtual presentation Customizable: Yes Geared for experienced developers, Core Web Services and SOA for J2EE Developers is a four day, lab-intensive course that provides an in-depth coverage of what J2EE developers need to know to design, implement, and deliver web services within the J2EE framework. In addition to introducing students to the fundamentals of Service Oriented Architectures (SOA) and the core standards that enable Web Services, it provides them hands-on experience with implementations of the Java XML and Web Service APIs including JAXP, JAXB, SAAJ, JAX-WS/RPC, WSEE, XWSS, and Apache Axis2. SOA and Web Services represent a groundbreaking evolution in distributed computing. The concepts are not altogether new, but the application of them, and the unanimous acceptance of core standards like HTTP, XML, SOAP, WSDL, and UDDI, has paved the way for XML Web Services and service-oriented architecture. Course Objectives: What You’ll Learn  Understand and work with Apache Axis2 and its enhanced capabilities Today's development environments are increasingly dominated by  Recognize security vulnerabilities associated with potential or sophisticated tooling that makes the initial development of web actual web services and design/implement effective defenses services less arduous. The production-level implementation, for those services and related resources. deployment, and maintenance of web services are far more complex and demanding. Prior to digging into the technical aspects of web services, students are given an introduction to Service-Oriented Architectures, Core Web Services and SOA for J2EE Developers focuses on providing a broad context for the purpose and goals for identifying providing an understanding of the fundamental technologies used and implementing web services. in web services. This understanding is critical to being able to diagnose, troubleshoot, tune, and perform other lifecycle activities. Students will explore at the current state of the art of Web services, what works and what doesn’t work, and also at newer standards, Working in a dynamic, interactive discussion and hands-on and how they fit into the Web services picture. Web services are programming environment, developers will be able to: still evolving rapidly, and this course will give you a thorough  Understand and apply the basic concepts of SOA to the understanding of the current Web services architecture, and the identification and design of web services technologies that support Web services including:  Understand and intelligently discuss Web Services and the core  SOAP/SAAJ – Simple Object Access Protocol - A remote technologies involved invocation (RPC) and messaging mechanism.  Design, develop, and deploy real-world J2EE Web Services  WSDL – Web services Description Language – An XML language  Expose existing Java components as XML Web Services that describes the interface and semantics of a Web service.  Write Java components that access remote Web Services  UDDI – Universal Description, Discovery, and Integration – A hosted by a third party standard for describing, publishing and finding Web services.  Read and understand a WSDL document  JAX-WS/RPC – Accessing Web services using Java  Understand the concepts behind REST and implement a REST-  REST- Representational State Transfer - A style of based web service implementing web services that is gaining increasing

Students will learn how to develop (and reuse!) essential Java and web services development and design skills and concepts properly, using best design practices, grounding them for advanced curriculum. Students will be prepared for designing and implementing real solutions, right after the class ends. Students will learn the importance of developing and maintaining well-designed web services applications.  Our courses are focused - no "fluff" included. We offer more than a “laundry list” approach to teaching. All lessons have clear objectives, are fundamental to core development and design practices, and are reinforced by hands-on labs and solid practical examples. Each lesson has performance driven objectives that ensure students will learn technologies and skills core to fundamental application design – nothing more, nothing less.  Our materials are comprehensive, and current. Our comprehensive manuals include not only a hard copy of the course presentation, but also detailed reference notes, pertinent diagrams and charts, current lists of suggested online resources and articles, and often technical tutorials or white papers geared to the topics at hand.  We set you up! Hands-on courses also include our unique materials for each student, complete with our LoadNGo Instant Classroom course set up DVD, software, and a multitude of learning resources that complement the course. Run the course right off the DVD – minimal set up for your company – maximum results for your students.  We foster "Learning by Doing". Progressive labs are designed in such a way that students get a firm grasp on fundamental skills while they work toward defending a complete application. All labs are take-home, and all solution code is presented in an easy to use self-study format for future use and review.  True content ownership gives us flexibility & quality above the rest. These course materials are wholly-owned by our authors and fully customizable - at little or no cost - to help you best meet your learning objectives. We have many dedicated experts available worldwide to instruct your team, and can provide services around the globe, either locally or virtually. We work closely with you to produce the most effective events and materials for your team, within your desired timeframe and budget.  We have to adhere to higher standards. As a courseware provider, our content and hands-on lab materials are licensed internationally by dozens of firms, and are therefore subject to very stringent quality requirements. Not only will your organization benefit from our own technical team’s technical expertise, but also the feedback of hundreds of students and trainers using these materials, worldwide, on a regular basis. This unique fact guarantees that our materials are not only robust and interesting, but also technically correct, current and of the highest quality and usability.  We bring years of practical, current experience into the classroom and content. Our instructors and course authors are also skilled mentors, Java, J2EE / JavaEE, .Net, SOA, and web services developers, architects and security-oriented professionals. We believe that learning, using and maintaining solid software execution and delivery methods are as important as gaining sharp coding skills. Best Practices for software development and execution, beyond technical coding skills, are enforced throughout all of our courses and discussions. Our team brings this extensive experience into every classroom and engagement.  We're skills-centric. Although our team has extensive experience using a variety of tools and solutions, our core content is “technology- centric”. Our aim is to teach you the best skills and solutions out there – not to sell you software from any particular vendor.  We're Java & J2EE authors and industry speakers. Our team was selected to write the online J2EE, EJB, EJB CMP-CMR and Web Services Tutorial Series for IBM developerWorks® ( These are the same instructors who train our classes and author the courseware. Most of our trainers/consultants have also authored additional articles on web services, EJB< Struts, J2EE and advanced Java topics, and are recognized speakers and presenters on the industry technical seminar circuit. Our team is comprised on several successful published authors. Members of our team have written or contributed to: Eclipse Kick Start, Mastering Eclipse; Professional Jakarta Struts; Using Java Tools for Extreme Programming; Mastering Resin; Mastering TomCat and others.
