Downloading file via Web Service using Apache CXF

Question

I try to develop Web Service which send file from server to client. I use Apache CXF for developing Web Serivce. Application is Spring based. First I tried to write simple test code:

applicationContext.xml

<import resource="classpath:META-INF/cxf/cxf.xml"/>
<import resource="classpath:META-INF/cxf/cxf-servlet.xml"/>

<bean class="com.llth.paymentgateway.webservice.PaymentGatewayReportingWebServiceImpl" id="paymentGatewayReportingWebService"/>

<jaxws:endpoint id="reportingWebService" implementor="#paymentGatewayReportingWebService" address="/ReportingWebService">
    <jaxws:properties>
        <entry key="mtom-enabled" value="true"/>
    </jaxws:properties>
</jaxws:endpoint>

PaymentGatewayReportingWebService.java Web Service inteface

@WebService
@SOAPBinding(style = SOAPBinding.Style.RPC)
public interface PaymentGatewayReportingWebService {

    @WebMethod(operationName = "downloadFile")
    public DataHandler downloadFile(String fileName);

}

PaymentGatewayReportingWebServiceImpl.java implementation of PaymentGatewayReportingWebService inteface

@WebService(endpointInterface = "com.llth.paymentgateway.webservice.PaymentGatewayReportingWebService")
public class PaymentGatewayReportingWebServiceImpl implements PaymentGatewayReportingWebService {

    @Override
    @XmlMimeType("application/octet-stream")
    public DataHandler downloadFile(String fileName) {
        FileDataSource dataSource = new FileDataSource(fileName);

        return new DataHandler(dataSource);
    }
}

When I import and execute Web Service method by soapUI I recevie the following response (copied from RAW tab)

and some binary data here

soapUI doesn't download anything. I don't know if everything is right or not. Should soapUI begin download the file? If soapUI should download the file then something is wrong. If yes, what is wrong?

Answer 1

In fact soapUI is giving you the right answer. That "some binary data here" is the file you asked for
