Java Web Services: Up and Running, 2nd Edition

Book description

Learn how to develop REST-style and SOAP-based web services and clients with this quick and thorough introduction. This hands-on book delivers a clear, pragmatic approach to web services by providing an architectural overview, complete working code examples, and short yet precise instructions for compiling, deploying, and executing them. You’ll learn how to write services from scratch and integrate existing services into your Java applications.

With greater emphasis on REST-style services, this second edition covers HttpServlet, Restlet, and JAX-RS APIs; jQuery clients against REST-style services; and JAX-WS for SOAP-based services. Code samples include an Apache Ant script that compiles, packages, and deploys web services.

  • Learn differences and similarities between REST-style and SOAP-based services
  • Program and deliver RESTful web services, using Java APIs and implementations
  • Explore RESTful web service clients written in Java, JavaScript, and Perl
  • Write SOAP-based web services with an emphasis on the application level
  • Examine the handler and transport levels in SOAP-based messaging
  • Learn wire-level security in HTTP(S), users/roles security, and WS-Security
  • Use a Java Application Server (JAS) as an alternative to a standalone web server
