The client is configured as follows:
<bean id="fcrsFactory"
class="org.apache.cxf.jaxws.JaxWsProxyFactoryBean" >
<property name="address"><value>${fcrs.url}</value></property>
<property
name="serviceClass"><value>com.tascet.wsdl.fcrs.v1.FacialRecognitionService</value></property>
<property
name="serviceName"><value>FacialRecognitionService</value></property>
<property
name="endpointName"><value>FacialRecognitionServicePort</value></property>
</bean>
<bean id="fcrs"
class="com.tascet.wsdl.fprs.v1.FingerprintRecognitionService"
factory-bean="fcrsFactory" factory-method="create" scope="prototype" />
The server is configured as follows:
<jaxws:endpoint id="fcrs"
implementor="#fcrsImpl"
endpointName="s:FacialRecognitionServicePort"
serviceName="s:FacialRecognitionService"
address="/FacialRecognitionService"
wsdlLocation="/WEB-INF/wsdl/FCRS.wsdl"
