JBoss at Work: A Practical Guide

10.14. J2EE Web Services Checklist

Before we move on to test the JAW Motors application's new Web Service functionality, let's recap what we've done to implement a J2EE 1.4 Web Service:

  • Created the InventoryEndpoint Service Endpoint Interface (SEI) to expose EJB methods as Web Service operations

  • Added a <service-endpoint> element to ejb-jar.xml to tell JBoss that the InventoryFacadeBean EJB implements the InventoryEndpoint Service Endpoint Interface

  • Generated the webservices.xml to register the Web Service and tie the InventoryEndpoint Service Endpoint Interface to an implementationthe InventoryFacadeBean

  • Created the JAX-RPC Mapping File to define JAX-RPC type mappings for the parameters and return values for the InventoryEndpoint's method

  • Generated the inventory-mapping.xml WSDL file to define the Web Service and tie it to XML Schema data types

  • Set the Web Service URL by modifying jboss.xml with the Inventory Web Service URL

  • Modified the InventoryFacadeBean:

    • Added Web Services-related XDoclet tags

    • Added the findAvailableCars( ) method and used an XML Schema-compatible data type%

  • Upgraded deployment by modifying the Ant build script:

    • Fixed XDoclet-generated descriptors

    • Modified the Web Service URL in jboss.xml

    • Used JWSDP to generate the JAX-RPC and WSDL files
