I have a .net client consuming a WCF duplex service.

I am now trying to add a java webservice to be called by the WCF service and call some methods in the WCF service.

I have added a ref to the java webservice from the WCF service and the can call methods in teh java WS from the WCF service.

I have added a reference to the WCF service to the java WS and the wsdl seems to parse correctly apart from these 2 warnings

[WARNING] SOAP port "WSDualHttpBinding_IAdderAndCaller": uses a non-standard SOAP 1.2 binding.
line 1 of file:/C:/Users/Ash/Documents/NetBeansProjects/WCFJavaTest/src/conf/xml-resources/web-service-references/AdderAndCaller/wsdl/localhost_24859/AdderAndCaller.svc.wsdl

[WARNING] ignoring operation "output": not request-response or one-way
line 1 of file:/C:/Users/Ash/Documents/NetBeansProjects/WCFJavaTest/src/conf/xml-resources/web-service-references/AdderAndCaller/wsdl/localhost_24859/AdderAndCaller.svc.wsdl

Problem is when I test my java web service and try to instantiate the WCF service using the following line:

Java Code: 
org.tempuri.AdderAndCaller moo = new org.tempuri.AdderAndCaller();
I get the following error:
java.lang.NullPointerException

I have a feeling that the error is due to the dualbinding being used.

Any help would be great.

Kind Regards
