如何在JAX-RS服务中读取授权标头

我是Authorization标头的新手，尝试使用JAX-RS服务创建授权（和身份验证）

我的JavaScript代码段如下所示：

            sUrl = getURL() + "/com.cabRoutePlanner.Login/Login";  
            var oHeaders = {};
            oHeaders['Authorization'] = "Basic " + btoa(getUserName() + ":" + getPassword());

            var request = {
                headers : oHeaders,
                requestUri : sUrl,
                data: connectionData,
                method : "POST"
            };
            OData.request(request, onSuccessForRegister, onRegError);

现在，我想在JAX-RS服务中读取此授权标头，即，在Java Rest服务中返回用户名和密码，并检查数据库。我感到困惑的是，我不知道如何使用此授权标头。如果有人可以向我展示REST服务中函数的声明，并只是访问我的用户名和passwrd，那将是很棒的。

我以某种方式编写了代码，并获得了Eclipse的一些直觉和大力帮助

@Path("/Log")
@POST
@Produces(MediaType.APPLICATION_JSON)
public Response log(HttpServletRequest req)throws JSONException
{
    JSONObject returnObject = new JSONObject();
    String authorization = req.getHeader("Authorization");
    if (authorization != null && authorization.startsWith("Basic")) 
    {
        //byte[] message = authorization.substring("Basic".length()).trim().getBytes();
        String credentials = authorization.substring("Basic".length()).trim();
        byte[] decoded = DatatypeConverter.parseBase64Binary(credentials);
        String decodedString = new String(decoded);
        String[] actualCredentials = decodedString.split(":");
        String ID = actualCredentials[0];
        String Password = actualCredentials[1];
        String Result = actualLog(ID, Password);
        if(Result.equals("ID Does not exist"))
        {
            returnObject.put("Result", "ID Does not exist");
            return Response.status(401).entity(returnObject).build();

        }
        else if(Result.equals("Password incorrect for given User"))
        {
            returnObject.put("Result", "Password incorrect for given User");
            return Response.status(401).entity(returnObject).build();
        }
        else
        {
            returnObject.put("Result", Result);
            return Response.status(200).entity(returnObject).build();
        }
    }
    else
    {
        returnObject.put("Result", "Authorization header wrong");
        return Response.status(401).entity(returnObject).build();
    }
}

现在，这是我正在获取的当前异常，我无法理解它：
