javaspaces - ServiceRegistrar 调用上的 JavaSpace 异常

Question

我今天在 GigaSpaces 的 Java 开发方面遇到了一个问题。我在tomcat下的网络应用程序给我带来了这样的失败

2013-08-15 10:13:29,217 [JavaSpaceFactory.java:57] 信息 - JavaSpaceFactory#getSpace java.security.AccessControlException: 访问被拒绝 (java.net.SocketPermission 127.0.0.1:4174 connect,resolve) jini://localhost :4174 与 localhost:4174 2013-08-15 10:13:29,218 [JavaSpaceFactory.java:59] 错误 - java.security.AccessControlException: 访问被拒绝 (java.net.SocketPermission 127.0.0.1:4174 connect,resolve)

这通过调用 ServiceRegistrar sr = locator.getRegistrar();

        jSpaceURL = CommandServiceImpl.getConfigProperty("jSpace.URL"); // jSpace.URL    = jini://localhost:4174
        LookupLocator locator = new LookupLocator(jSpaceURL);
        host = locator.getHost();
        port = locator.getPort();
        logger.info("lookup service jini://" + host + ":" + port);
        ServiceRegistrar sr = locator.getRegistrar(); (!!!!!!!!!!!!!!!!!!!!   Here is Exception java.net.SocketPermission 127.0.0.1:4174 connect,resolve  !!!!!!!!!!!!!!!!!!)
        logger.info("registrar is ok");

tomcat 已进入 $CATALINA_HOME/conf/catalina.policy 条目

grant { ....... 权限 java.net.SocketPermission "*", "accept, connect, listen, resolve";

.....................

};

GigaSpace 有进入 $GIGASPACES_HOME/policy/gigaspaces.policy 的入口权限 java.net.SocketPermission "*", "listen, resolve, connect, accept";

这种违规行为可能是什么情况？
