Subject from axis 1.2 RC invoking .net web service getting NullPinterException
Date Fri, 05 Oct 2007 15:44:04 GMT

Hi,

     I have Tomcat and axis 1.2 RC installed. client has .Net web service
and they have sent us WSDL file, from this WSDL i have generated client
Stub. I am invoking their service. 

i am getting NullPointerException.

Code to invoke :

String url = "https://san.go.ca/travel/book.asmx";
SampleStub objStub = new SampleStub;
objStub._setProperty(javax.xml.rpc.Stub.ENDPOINT_ADDRESS_PROPERTY, url);
if(objbooking!=null)
{
     objStub.statusUpdate(objbooking);
}



And the code from where I got the NullPointerException ( code from
SampleStub that invoking )-


java.lang.Object _resp = _call.invoke(new java.lang.Object[] {booking});

when invoking - call.invoke then it's return nulll.  in _resp it stored null
.......so nullpointerexception given..

see the code-----

 public boolean statusUpdate(com.kedintive.goptvel.repnse.Booking booking)
throws java.rmi.RemoteException {
        if (super.cachedEndpoint == null) {
            throw new org.apache.axis.NoEndPointException();
        }
        org.apache.axis.client.Call _call = createCall();
        _call.setOperation(_operations[0]);
        _call.setUseSOAPAction(true);
         
_call.setSOAPActionURI("http://sancom.com/dhk/poptravel/XXX/SampleUpdate/StatusUpdate");
        _call.setEncodingStyle(null);
        _call.setProperty(org.apache.axis.client.Call.SEND_TYPE_ATTR,
Boolean.FALSE);
        _call.setProperty(org.apache.axis.AxisEngine.PROP_DOMULTIREFS,
Boolean.FALSE);
       
_call.setSOAPVersion(org.apache.axis.soap.SOAPConstants.SOAP11_CONSTANTS);
        _call.setOperationName(new
javax.xml.namespace.QName("http://sancom.com/dhk/poptravel/order",
"StatusUpdate"));

        setRequestHeaders(_call);
        setAttachments(_call);
        java.lang.Object _resp = _call.invoke(new java.lang.Object[]
{booking});

        if (_resp instanceof java.rmi.RemoteException) {
            throw (java.rmi.RemoteException)_resp;
        }
        else {
            extractAttachments(_call);
            try {
                return ((java.lang.Boolean) _resp).booleanValue();
            } catch (java.lang.Exception _exception) {
                return ((java.lang.Boolean)
org.apache.axis.utils.JavaUtils.convert(_resp,
boolean.class)).booleanValue();
            }
        }
    }
