10.8. JAX-RPC Mapping File

The J2EE-standard JAX-RPC mapping file helps the JAX-RPC compiler map Java objects to WSDL objects. If the Java objects are complex, the JAX-RPC and WSDL files also will be complex. Example 10-4 is the inventory-mapping.xml JAX-RPC mapping file that the JAW Motors application uses.

Example 10-4. inventory-mapping.xml
 <?xml version="1.0" encoding="UTF-8"?> <java-wsdl-mapping xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee  http://www.ibm.com/webservices/xsd/j2ee_jaxrpc_mapping_1_1.xsd" version="1.1">   <package-mapping>     <package-type>com.jbossatwork.ws</package-type>     <namespaceURI>http://localhost:8080/jbossatwork-ws/types</namespaceURI>   </package-mapping>   <package-mapping>     <package-type>com.jbossatwork.ws</package-type>     <namespaceURI>http://localhost:8080/jbossatwork-ws</namespaceURI>   </package-mapping>   <java-xml-type-mapping>     <java-type>com.jbossatwork.dto.CarDTOArray</java-type>     <root-type-qname xmlns:typeNS="http://localhost:8080/jbossatwork-ws/types">       typeNS:CarDTOArray     </root-type-qname>     <qname-scope>complexType</qname-scope>     <variable-mapping>       <java-variable-name>cars</java-variable-name>       <xml-element-name>cars</xml-element-name>     </variable-mapping>   </java-xml-type-mapping>   <java-xml-type-mapping>     <java-type>com.jbossatwork.dto.CarDTO</java-type>     <root-type-qname xmlns:typeNS="http://localhost:8080/jbossatwork-ws/types">       typeNS:CarDTO     </root-type-qname>     <qname-scope>complexType</qname-scope>     <variable-mapping>       <java-variable-name>id</java-variable-name>       <xml-element-name>id</xml-element-name>     </variable-mapping>     <variable-mapping>       <java-variable-name>make</java-variable-name>       <xml-element-name>make</xml-element-name>     </variable-mapping>     <variable-mapping>       <java-variable-name>model</java-variable-name>       <xml-element-name>model</xml-element-name>     </variable-mapping>     <variable-mapping>       <java-variable-name>modelYear</java-variable-name>       <xml-element-name>modelYear</xml-element-name>     </variable-mapping>     <variable-mapping>       <java-variable-name>status</java-variable-name>       <xml-element-name>status</xml-element-name>     </variable-mapping>   </java-xml-type-mapping>   <service-interface-mapping>     <service-interface>com.jbossatwork.ws.InventoryService</service-interface>     <wsdl-service-name xmlns:serviceNS="http://localhost:8080/jbossatwork-ws">       serviceNS:InventoryService     </wsdl-service-name>     <port-mapping>       <port-name>InventoryEndpointPort</port-name>       <java-port-name>InventoryEndpointPort</java-port-name>     </port-mapping>   </service-interface-mapping>   <service-endpoint-interface-mapping>     <service-endpoint-interface>       com.jbossatwork.ws.InventoryEndpoint     </service-endpoint-interface>     <wsdl-port-type xmlns:portTypeNS="http://localhost:8080/jbossatwork-ws">       portTypeNS:InventoryEndpoint     </wsdl-port-type>     <wsdl-binding xmlns:bindingNS="http://localhost:8080/jbossatwork-ws">       bindingNS:InventoryEndpointBinding     </wsdl-binding>     <service-endpoint-method-mapping>       <java-method-name>findAvailableCars</java-method-name>       <wsdl-operation>findAvailableCars</wsdl-operation>       <wsdl-return-value-mapping>         <method-return-value>com.jbossatwork.dto.CarDTOArray</method-return-value>         <wsdl-message xmlns:wsdlMsgNS="http://localhost:8080/jbossatwork-ws">           wsdlMsgNS:InventoryEndpoint_findAvailableCarsResponse         </wsdl-message>         <wsdl-message-part-name>result</wsdl-message-part-name>       </wsdl-return-value-mapping>     </service-endpoint-method-mapping>   </service-endpoint-interface-mapping> </java-wsdl-mapping> 

This JAX-RPC mapping file tells JBoss that the InventoryEndpoint Service Endpoint Interface has a findAvailableCars( ) method that takes no parameters and returns a CarDTOArray.

Mapping between WSDL data types and Java object types is tedious. Notice how one return type, CarDTOArray, explodes into two <java-xml-type-mapping> elementsone for the CarDTOArray itself and the other for the CarDTO. Besides mapping a Java object to a WSDL data type, each <java-xml-type-mapping> element lists each of the object's data members with a <variable-mapping> sub-element.
