Web Services

Duration : 20 Hrs

The Java Web Services Development Pack  is a software development kit  for developing  Web Services, Web applications and Java applications with the emerging  technologies for Java.

  • Strong Java programming skills are essential.
  • Students must be able to read XML documents and to write well-formed XML by hand
  • Knowledge of XML Schema will be helpful, too, but is not a strict prerequisite.
  • Experience with other Java EE standards, especially servlets and JSP, will be very helpful in class, but is not strictly required.
Learning Objectives
  • Be able to describe the interoperable web services architecture, including the roles of SOAP and WSDL in component-based services and XML and HTTP in the REST architecture.
  • Understand the importance of the WS-I Basic Profile for interoperable web services.
  • Build JAX-WS services and clients that take full advantage of the automated data binding of JAXB.
  • Build WSDL-to-Java and Java-to-WSDL services, with equal facility.
  • Apply advanced techniques and best practices including proper exception handling, care around possible polymorphism, and use of context and lifecycle services.
  • Use lower-level SOAP and XML APIs for services and/or clients.
  • Customize data binding by specifying specific type mappings or altering method or parameter names.
  • Incorporate binary data, such as images, into service and client code.

Timeline              :                  12 days.
Server Support   :                  Tomcat or Web Sphere
IDE Support        :                  Eclipse Helios


Students who take Java Web Services Online Training from Evanta Technologies will learn the differences between SOAP-based and REST-style services, as fine as why both approaches are considered superior to distributed-object architecture, such as  .NET frameworks & Java EE.  Web service clients written in Perl, Ruby and Java are provided to illustrate the language neutrality of web services.

 Web services are spread network aware software components that communicate via platform-independent specifications such as SOAP and REST.  Web services can be written in any modern programming language and consumed by applications written in other languages and/or running on other platforms.  In a service-oriented architecture, large-scale applications can be created by loosely-coupled relationships among multiple services.

No doubt, we’re in the golden age of internet and web development. From the outermost reaches of the globe, to our smartphones, the world is connected in many ways once unbelievable. If you’re passionate about the opportunities available to Evanta Tech people, the Internet Applications and Web Development program will open doors to the online world of infinite career potential.

You will be focused on the construction of various types of web applications using leading web environments, tools, servers, databases and languages. As well, you’ll learn the basics of both out-dated web deployment platforms as well as new emerging mobile platforms. Along the way, you’ll develop an understanding of basic hardware, networking and operating systems as well as the installation and outline of web and email servers in Windows and Linux. You’ll also learn about leading-edge technologies such as social networking systems and semantic web applications.

At the completion of course, you will have a various set of skills required to build secure, reliable and useful web applications using industry standard photo, graphics, animation, database, page design and programming tools.

Why study Web Services & Applications?

Studying Web Services and Applications you’ll learn to transform online banking or create the next evolution of social media applications — the possibilities are limitless. As a Web Designer you’ll have skilled knowledge of the inter-connectivity between databases, communication networks and information retrieval to create online applications and services.

Our Evanta Technologies of high-performance computing, networks and artificial intelligence will give you experience with the tools you will use in the field. Through labs, lectures and projects, you’ll also

  • Design web-centric applications that provide intuitive customer-oriented services
  • Develop distributed software systems that scale to meet the demands of contemporary organizations
  • Investigate opportunities for the deployment of applications across multiple hardware devices and platforms
