Accessing WSO2 ESB proxy in java program

1
votes

I have configured one wsdl proxy for external wsdl in WSO2 esb. Its successfully created proxy. While creating proxy, I have not selected Publish Same Service Contract check box. If we are consuming external web services, is it mandatory to check? When I click on try it, it is not showing operations which are available in wsdl.

If at all the above issues gets solved, we need to access the proxy from our java project. How can we access WSO2 ESB proxy in our java program?

Thanks in advance.

Thanks, Raghu

Yes you need to check Publish Same Service Contract if you want to publish the same WSDL.

in java code you can write a simple axis2 client like shown below. To the enxpoint of your proxy.

   public OMElement sendReceive(OMElement payload, String endPointReference, String operation)
            throws AxisFault {
        ServiceClient sender;
        Options options;
        OMElement response = null;

        try {
            sender = new ServiceClient();
            options = new Options();
            options.setTo(new EndpointReference(endPointReference));
            options.setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED, Boolean.FALSE);
            options.setTimeOutInMilliSeconds(45000);
            options.setAction("urn:" + operation);
            sender.setOptions(options);

            response = sender.sendReceive(payload);

        } catch (AxisFault axisFault) {
            throw new AxisFault("AxisFault while getting response :" + axisFault.getMessage(), axisFault);
        }
        Assert.assertNotNull(response);
        return response;
    }

You can get the sample payload by tying a tool like soap UI.

Thank You, Dharshana.

Try like this:

    CentralUuidService service = new CentralUuidService(new URL("http://wls02.tigeritbd.com:8280/services/CentralUuidService?wsdl"),new QName("http://bean.service.uuid.gov.bd/", "CentralUuidService"));

    GetBirthPlaceServiceResponse response = service.getCentralUuidServiceHttpSoap11Endpoint().getBirthPlace(request);        
    if(response != null) {
        System.out.println("Operation status is:"+response.isOperationStatus());
    }
}
