use existing http client for SOAP call

I've got a working Dropwizard project, which has several ways of getting data it needs. One of those ways is the JAX-RS client that Dropwizard provides, the JerseyClient. This client is configured so that it suits my needs (uses the proper proxy, timeouts etc...)

Now my project has a new requirement for which I need to do a SOAP call. I've got that functionally working using the following code:

// not the actual structure, edited to make a minimal example
// SERVICE_QNAME and PORT_QNAME are hardcoded strings, config.url comes
// from the configuration
import javax.xml.ws.*;
import javax.xml.ws.soap.*;
import javax.xml.namespace.QName;

Service service = Service.create(SERVICE_QNAME);
service.addPort(PORT_QNAME, SOAPBinding.SOAP11HTTP_BINDING, config.url);
Dispatch dispatch = service.createDispatch(PORT_QNAME, SOAPMessage.class, Service.Mode.MESSAGE);
dispatch.getRequestContext().put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, config.url);


Message message = MessageFactory.newInstance(SOAPConstants.SOAP_1_2_PROTOCOL).createMessage();
// do stuff to fill the message
response = dispatch.invoke(message);

This is all out-of-the-box behaviour, anything happening here is provided either by java (8) or Dropwizard.

This code however uses it's own http connectors, bypassing anything I've set up in my JAX-RS client. I would like to re-use the JerseyClient's http capabilities in the JAX-WS client in a non-copy-paste kinda way.

Is there a way I can set up the Dispatch so that it will use the existing http connectors? Or some other SOAP client to achieve the same?

Solution

  • Thank you @zloster for the research and suggestions. I decided to take another route however.

    I found the SAAJ standard and am using that now. I created a subclass for javax.xml.soap.SOAPConnection and based that on com.sun.xml.internal.messaging.saaj.client.p2p.HttpSOAPConnection. That part wasn't all that hard and leaves me with a relatively small class.

    Now in my code I replaced the code above with something along these lines: 

    SOAPConnection soapConnection = new JerseySOAPConnection(httpClient, soapProtocol);
Message message = MessageFactory.newInstance(soapProtocol).createMessage();
// do stuff to fill the message
response = soapConnection.call(message, config.url);

    Due to my implementation not all that portable, but I don't really need it to be. Again, thanks for those who helped me get to this!
