java使用smartGWT客户端应用程序通过SOAP调用web服务操作

Question

我在使用smartGWT客户端应用程序通过SOAP调用web服务操作时遇到问题

我有两个应用程序在同一个TomCat服务器上运行：

1. 具有wsdl定义的某些操作的web服务（由apache CXF 2.5从java类生成）
2. smartGWT客户端应用程序

如果我使用SoapUI调用操作getUser，那么一切都正常。 但如果我通过smartGWT应用程序调用getUser操作，则会出现以下异常：

在日志中我有这样一个：

答复：

--------------------------------------

我调用webservice的代码是：

    XMLTools.loadWSDL("http://localhost:8080/healthCard/userManagementService?wsdl", new WSDLLoadCallback() {
      public void execute(WebService webService) {
          webservice = webService;
      }
    });

    return form;

  }

  class UserForm extends DynamicForm {
    public void callService() {
      if (webservice == null) {
        SC.say("Please try again in a moment  - still loading web service descriptor");
      } else {
        setValue("username", "Loading...");
        Map data = new LinkedHashMap();
        data.put("firstname", getValueAsString("username"));


        webservice.callOperation("getUser", data, null, new WebServiceCallback() {

          public void execute(Object[] data, JavaScriptObject xmlDoc, RPCResponse rpcResponse,
              JavaScriptObject wsRequest) {
            UserForm.this.setValue("username", (String) data[0]);
          }
        });
      }
    }
  }

你能帮我一下吗
