SOA Using Java Web Services by Mark D. Hansen

By Mark D. Hansen

Expert recommendations and cutting-edge Code Examples

SOA utilizing Java™ internet Services is a hands-on consultant to imposing net providers and repair orientated structure (SOA) with today’s Java EE five and Java SE 6 structures. writer Mark Hansen offers in particular aspect the data that company builders and designers have to prevail, from best-practice layout strategies to cutting-edge code samples.

Hansen covers growing, deploying, and invoking net companies that may be composed into loosely coupled SOA purposes. He starts off by way of reviewing the “big picture,” together with the demanding situations of Java-based SOA improvement and the restrictions of conventional methods. subsequent, he systematically introduces the most recent Java net providers (JWS) APIs and walks via growing internet providers that combine right into a entire SOA resolution. eventually, he indicates how program frameworks according to JWS can streamline the whole SOA improvement approach and introduces one such framework: SOA-J.

The book

  • Introduces useful recommendations for coping with the complexity of internet providers and SOA, together with best-practice layout examples
  • Offers hard-won insights into construction potent SOA functions with Java net companies
  • Illuminates fresh significant JWS improvements–including complete chapters on JAX-WS 2.0
  • Thoroughly explains SOA integration utilizing WSDL, cleaning soap, Java/XML mapping, and JAXB 2.0 information binding
  • Walks step-by-step via packaging and deploying internet providers parts on Java EE five with JSR-181 (WS-Metadata 2.0) and JSR-109
  • Includes particular code suggestions for plenty of improvement matters, from publishing relaxation endpoints to eating cleaning soap prone with WSDL
  • Presents an entire case examine utilizing the JWS APIs, including an Ajax entrance finish, to construct a SOA software integrating Amazon, Yahoo purchasing, and eBay
  • Contains hundreds of thousands of code samples–all verified with the GlassFish Java EE five reference implementation–that are downloadable from the better half site, http://soabook.com.

Languages, Design Methods, and Tools for Electronic System Design: Selected Contributions from FDL 2015

This publication brings jointly a variety of the simplest papers from the eighteenth variation of the discussion board on specification and layout Languages convention (FDL), which came about on September 14-16, 2015, in Barcelona, Spain. FDL is a well-established foreign discussion board dedicated to dissemination of analysis effects, useful studies and new principles within the program of specification, layout and verification languages to the layout, modeling and verification of built-in circuits, complicated hardware/software embedded structures, and mixed-technology structures.

Sample text

The deployment subsystem associates a Java target with the WSDL document containing the WSDL operation it is bound to. , within a UDDI registry). Configuring SOAP handlers. The deployment subsystem configures the necessary SOAP handlers needed to provide QoS pre- or postinvocation of the Java target. These handlers provide services such as authentication, reliability, and encryption. Although the invocation subsystem invokes the handlers, they are configured and associated with a Web service by the deployment subsystem.

In some Web Services platforms, the WSDL is supplied without an endpoint being defined, and the endpoint is “filled in” by the deployment subsystem from a deployment descriptor. As you can see from this description, the deployment subsystem needs to do a lot of rather nonglamorous tasks. 7 Figure 1–4 shows the possible deployment descriptors used by a Web Services platform and their relationships to the underlying containers. As shown in Figure 1–4, the Web Services platform may span multiple containers.

2. This page intentionally left blank C H A P T E R 2 An Overview of Java Web Services This chapter provides an overview of the capabilities provided by the Java Web Service (JWS) standards supported by Java EE 5 and Java SE 6. 1) by looking at the role of JWS in SOA application development. 2), some of the Java EE 5 “ease-of-use” features are covered. Making the programming process easier was stated as the number-one goal for the release of Java EE 5 Web Services, so right up front there is a quick review of these ease-of-use design decisions and their impact on development.
