本地计算机上的Tomcat可能在未启用安全性的情况下运行。在实际的服务器上，情况并非如此，安全管理器处于活动状态。可以为您的应用程序授予所需的SocketPermission权限，例如将以下内容放入Tomcat安全策略文件中：

grant codeBase "file:${catalina.base}/webapps/your_app_root/-" {
  permission java.net.SocketPermission "www.abc.com:80", "connect";
};

这应该进入策略文件，该文件通常位于conf/catalina.policy下，但您的安装可能会有所不同。您应该使用正确的URI替换file: URI。

请在此处阅读有关Tomcat安全管理器的详细文档：http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html。
