java如何通过soap调用webservice接口【No Deserializer found to deserialize】

[fangquan1980]

public static String getService() {
	       URL url = null;
	       try {
	           url=new URL("http://XXX.XXX.XXX.XXX/aaa/services/MailCsService");
	       } catch (MalformedURLException mue) {
	          return mue.getMessage();
	         }
	             // This is the main SOAP object
	       Call soapCall = new Call();
	     soapCall.setEncodingStyleURI(Constants.NS_URI_SOAP_ENC);
	     soapCall.setTargetObjectURI("MailCsService");
	  
	       soapCall.setMethodName("getMails");
	 
	       Vector soapParams = new Vector();
	       Parameter isbnParam1 = new Parameter("in0", String.class, "0", null);
	       Parameter isbnParam2 = new Parameter("in1", String.class, "aaa", null);
	       Parameter isbnParam3 = new Parameter("in2", String.class, "bbbb", null);
	       soapParams.addElement(isbnParam1);
	       soapParams.addElement(isbnParam2);
	       soapParams.addElement(isbnParam3);
	       soapCall.setParams(soapParams);
	       System.out.println(1);
	       try {
	          // Invoke the remote method on the object
	    	  System.out.println(2);
	    	  Response soapResponse = null;
	          soapResponse = soapCall.invoke(url,"getMails");
	          System.out.println(3);
	          // Check to see if there is an error, return "N/A"
	          if (soapResponse.generatedFault()) {
	              Fault fault = soapResponse.getFault();	              
	             
	              System.err.println("Generated fault: ");
	              System.out.println("Fault Code = " + fault.getFaultCode());
	              System.out.println("Fault String = " + fault.getFaultString());

	             System.out.println("qqq");
	             return f;
	          } else {
	             // read result
	        	  System.out.println("2qqq");
	             Parameter soapResult = soapResponse.getReturnValue ();
	             // get a string from the result
	             return soapResult.getValue().toString();
	          }
	       } catch (SOAPException se) {
	    	   System.out.println("3qqq");
	          return se.getMessage();
	       }
	    }

	public static void main(String[] args) throws Exception {
		
		System.out.println(getService());
	}

老是显示
