get webservice and invoke it

[simonsays]

this might not be the right place to ask since its proabably because i dont understand how to invoke the webservice right but here i go anyway.

i want to talk to the amazon webservice

   <bean id="isbnService" class="dk.bytenbog.model.service.impl.AmazonISBNServiceImpl">
        <property name="service"><ref="isbnServiceProxy"/></property>
    </bean>

    <bean id="isbnServiceProxy" class="org.springframework.remoting.jaxrpc.LocalJaxRpcServiceFactoryBean">
        <property name="wsdlDocumentUrl">
            <value>http&#58;//webservices.amazon.com/AWSECommerceService/UK/AWSECommerceService.wsdl</value>
        </property>
        <property name="namespaceUri"><value>http&#58;//webservices.amazon.com/AWSECommerceService/2004-10-19</value></property>
    <property name="serviceName"><value>AWSECommerceService</value></property>
    </bean>


public class AmazonISBNServiceImpl implements ISBNService &#123;

    private Service service;

   private String targetNamespace = "http&#58;//xml.amazon.com/AWSECommerceService/2004-08-01";

    private QName operationName = new QName&#40;targetNamespace, "ItemLookup"&#41;;

    public void setService&#40;Service service&#41; &#123;
        this.service = service;
    &#125;

    public Book getBook&#40;String isbn&#41; throws ISBNLookupException &#123;

        Call call = &#40;Call&#41; this.service.createCall&#40;&#41;;
             call.setOperationName&#40;operationName&#41;;
             call.addParameter&#40; "SubscriptionId", service.getServiceName&#40;&#41;, ParameterMode.INOUT &#41;;
             call.setReturnType&#40; XMLType.XSD_STRING &#41;;
						 String s = &#40;String &#41;call.invoke&#40; new Object&#91;&#93; &#123;"XXXXXXXX"&#125; &#41;;
						 
						 &#125;

shouldent this just return a string with the SubscriptionId that i send to it


i get a

aultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.generalException
faultSubcode:
faultString: No client transport named 'null' found!



if someone could point me in the right direction it would be verry helpfull.

Spring supports JAX-RPC like protocols, but does not implement Webservice protocol. So you something like Axis : http://ws.apache.org/axis/ additionally.

How to use Axis with Spring, best look at the jpetstore example, which comes which the distribution.

There look specially at the classes:
org.springframework.samples.jpetstore.service.clie nt.*

And the configuration file : clientContext.xml in the client subdirectory.
To address your requirements - invoking a non - rmi based interface, specially also look at the:
org.springframework.remoting.jaxrpc.JaxRpcPortProx yFactoryBean class

Hope that helps
