SAX Exception while deserialzing the soap request.

["Pasula, Venugopal (Consultant)" <Ve...@GTECH.COM>]

Hi,
   I am getting the following SAXException while deserializing the SOAP request.The weired thing is, it is working fine when I create stubs in the client side and access thru those stubs.

            ConnectInteractiveWebServiceServiceLocator serv = new ConnectInteractiveWebServiceServiceLocator();
            ConnectInteractiveWebService port = serv.getConnectInteractiveWebServicePort();
            return port.execute(functionName, req);

  But when I use the axis API directly without creating the stubs, then I am getting the SAX exception. Here is the code I have written. The same code is working fine in all the machines. I am getting the problem on couple of machines. I want know why this problem is appearing only those machines. we are using axis 1.2RC2 on both client and server. I attached the error statck trace at the bottom. please find it. this is the code I am using to invoke webservice with out creating the stubs.Can you please tell me where I am doing wrong?? I really appreciate your response.

    	Object[] arg = new Object[2];
    	Service serv = new org.apache.axis.client.Service();
    	TypeMappingRegistry tmr = serv.getTypeMappingRegistry();
    	TypeMapping tm = tmr.getDefaultTypeMapping();
    	tm.register(NameValuePair[].class,new QName("http://service.escb2b.gtech.com", "ArrayoffNameValuePair"),
    			new org.apache.axis.encoding.ser.ArraySerializerFactory(),
    			new org.apache.axis.encoding.ser.ArrayDeserializerFactory());
    	tm.register(NameValuePair.class, new QName("http://service.escb2b.gtech.com", "NameValuePair"),
    			new org.apache.axis.encoding.ser.BeanSerializerFactory(NameValuePair.class,new QName			           ("http://service.escb2b.gtech.com", "NameValuePair")),
    			new org.apache.axis.encoding.ser.BeanDeserializerFactory(NameValuePair.class,new QName                         	           ("http://service.escb2b.gtech.com", "NameValuePair")));

    	NameValuePair[] nvpReq = fromMap(req);
    	arg[0]="execute";
    	arg[1]=nvpReq;

    	String operationResponse = "executeResponse";
    	String operationReturn = "executeReturn";
    	RPCElement rpc = new org.apache.axis.message.RPCElement("http://service.escb2b.gtech.com", "execute", arg);
    	SOAPEnvelope env = new org.apache.axis.message.SOAPEnvelope();
    	MessageContext msgctx = new org.apache.axis.MessageContext(new org.apache.axis.client.AxisClient());

    	msgctx.setTypeMappingRegistry((org.apache.axis.encoding.TypeMappingRegistry)tmr);
    	Call cal = serv.createCall(new QName("ConnectInteractiveWebServicePort"), new QName("execute"));
        cal.setTargetEndpointAddress(endpoint);
    	cal.setReturnType(new QName("http://service.escb2b.gtech.com", "ArrayofNameValuePair"));
    	env.addBodyElement(rpc);
    	SOAPEnvelope resp = ((org.apache.axis.client.Call)cal).invoke(env);
    	RPCElement rpcelm = (org.apache.axis.message.RPCElement)resp.getBodyByName 	                    ("http://service.escb2b.gtech.com",operationResponse);
    	RPCParam rpcparam =  rpcelm.getParam(operationReturn);
    	NameValuePair[] result = (NameValuePair[])rpcparam.getObjectValue();


Thanks, Venu
