****client call webservice error(have ws-policy)

问题是这样的：

怎样编写client端代码调用一个webservice, 这个WS是deploy在weblogic上的，重点是做了ws-policy配置（需要用户名，密码认证），他们只提供给了我们WSDL。

我做了下面这些，可还是调用失败，并且错误信息不明确，哪为高手指点下小女子。不知到是否还需要别的配置, rampart ?

1. 新建了一个java项目，导入Axis2 (1.6.2) jar包。

   1. 用WSDL2Java生成客户端代码(基于wsdl文件） 网上说WSDL2Java会自动把wsdl里的policy文件自动添加到生成的java文件里，参考：https://axis.apache.org/axis2/java/core/docs/WS_policy.html#client

   xxxStub
   xxxCallbackHandler

2. Client代码
   // Create stub
   xxxStub stub = new xxxStub();

   // Set userName, password
   HttpTransportProperties.Authenticator basicAuthentication = new HttpTransportProperties.Authenticator();
   basicAuthentication.setUsername("***");
   basicAuthentication.setPassword("***");
   stub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, basicAuthentication);

   // Prepare input parameters
   ...

   // Set parameters
   ...

   // Invoke Services
   GetReportResponse response = stub.getReport(parameters);

   // Get result
   ... = response.getGetReportResult();

3. 错误信息：
