我按照本指南将 ESB 与 Identity Server 集成。
我试过 wso2esb-4.6.0 和 wso2is-4.1.0
以下是我的步骤：
将 WSO2 Identity Server 配置为 XACML 引擎并启动 Identity Server。
在 WSO2 ESB 中配置权利中介并启动 ESB。
在 IDE 中运行客户端代码。
但是发生了 ESBEntitlementMediator错误。
在 ESB 命令窗口中，出现以下错误：
[2013-06-25 22:33:05,236] ERROR - EntitlementMediator Error occurred while evaluating the policy java.lang.NullPointerException

在 IS 命令窗口中，出现以下错误：

在客户端 IDE 中，控制台中会出现以下消息：

有人知道吗？
