webservice调⽤报错400
直接在地址栏中输⼊地址和⽤户名，浏览器能够正常显⽰wsdl⽂件，但是⼯具调⽤就报错了。
我的调⽤的⽅法是这样的，为什么执⾏完之后报400错误，求⾼⼿指点：
String url = "10.10.30.12:50000/dir/wsdl?p=sa/cea12ef812243d8cac57203bb509d6fb";
String method = "OI_EOS2SAP_Report_REQ";
Service service = new Service();
Call call = (Call) ateCall();
call.setTargetEndpointAddress(new java.URL(url));
call.setOperationName(method);
call.setUsername("DRPSOAP");
call.setPassword("DRPSOAP");
String[] strs = new String[] {"1","2"};
List return_value = (List) call.invoke(strs);
参数是随意些的，应该不影响
