The response MUST include a WWW-Authenticate header field (section 14.46) containing a challenge applicable to the requested resource. The client MAY repeat the request with a suitable Authorization header field (section 14.8). If the request already included Authorization credentials, then the 401 response indicates that authorization has been refused for those credentials. If the 401 response contains the same challenge as the prior response, and the user agent has already attempted authentication at least once, then the user SHOULD be presented the entity that was given in the response, since that entity MAY include relevant diagnostic information. HTTP access authentication is explained in section 11.</FONT></P>

操作步骤：
1、检查WebLogic控制台标记,搜索 Security ,检查当前WLS的Realm名字例如：myrealm;
<20XX-12-5 下午03时14分25秒 CST> <Notice> <Security> <BEA-090082> <Security initializing using security realm myrealm.>
2、以上异常提示表示WebServices请求身份认证没有通过,不允许访问服务器资源，此时调用方式必须设置访问账号、以及密码，服务器将拒绝请求;
String endpoint = "http://localhost:7001/MyServicesWeb/services/SayHello";
Service service = new Service();

Call call = (Call) service.createCall();

//设置Security Realm方式一
// //远程调用用户名设置(HTTP统一认证账号)
// call.setUsername("weblogic");//wstest/hb_hsxf
// //远程调用密码设置，黄石公众诉求(HTTP统一认证密码)
// call.setPassword("passw0rd");
//设置Security Realm方式二
call.setProperty(org.apache.axis.client.Call.USERNAME_PROPERTY, "weblogic"); //账号
call.setProperty(org.apache.axis.client.Call.PASSWORD_PROPERTY,"passw0rd1");//密码

call.setTargetEndpointAddress(new java.net.URL(endpoint));
//设置远程调用方法路径及方法名称
call.setOperationName(new QName("urn:SayHello", "getHello"));
//传入xml文档字符串，返回数据校验错误字符串
//String d = (String) call.invoke(new Object[] {Document.asXML()});
String d = (String) call.invoke(new Object[]{"本地调用"});

System.out.println("Debug-Info: WSClient.callLocalhost Response $d>> "+d);
