    Tomcat on your local machine is probably running without security turned on. On the actual server this is not the case and security manager is active. It is possible to grant the required SocketPermission privileges for your application for example by putting the following into the Tomcat security policy file:

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

    This should go into the policy file, which is normally under conf/catalina.policy but your installation may differ. You should replace the file: URI with the correct one for your case.

    Please also read the detailed documentation on Tomcat security manager here: http://tomcat.apache.org/tomcat-6.0-doc/security-manager-howto.html.
