Answer 1

首先写一个配置文件security.policy，内容如下  grant   {   
  permission   java.security.AllPermission;   
  };   然后，在你的client jvm启动参数中加入 java -Djava.security.policy=security.policy ...

java.security.AccessControlException: access denied (java.net.SocketPermission 127.0.0.1:1099 connect,resolve)参考这个吧，以前整理的 ：http://www.java2000.net/viewthread.jsp?tid=1152应该是配置问题，
/*
 * Only grant permissions to the local class path (the current directory).
 */
grant codeBase "file:." {
    permission java.net.SocketPermission "*:1024-", "connect,accept";
};
