Unable to instantiate SOAP Client - Failing with NullPointerException

While instantiating a SOAP client, I get NullPointerException

@WebServiceClient(name = "QWEServiceManager", targetNamespace = "http://external.ws.services.abc.com/", wsdlLocation = "file:/C:/Users/XYZ/Desktop/77777/QWEServiceManagerService.wsdl")
public class QWEServiceManagerService extends Service

When I try to create an instance of the client to call the SOAP service 

QWEServiceManagerService serv = new QWEServiceManagerService()

the above throws 

Exception in thread "main" javax.xml.ws.WebServiceException: Unable to createEndpointReference Provider
    at javax.xml.ws.spi.Provider.provider(Provider.java:160)
    at javax.xml.ws.Service.<init>(Service.java:92)

The problem was with the fact that Java stopped providing default Provider Implementation above Java 6+.

It tries to find the Impl via following steps:

  • First By Service Loader
  • From JDK Properties (from $java.home/lib/jaxws.properties)
  • Use the system property
  • Lookup Using OSGi Service Loader

So, in simple, adding a dependency with implementation of provider solves the issue.

For me, adding jaxws-rt dependency solved the issue.

Note: I faced another dependency issue for which I did need to add another dependency to stax-ex to resolve all my dependency issues.
