+// the NOAA web server.  You might create a "grant" entries like this:
+//
+// The permissions granted to the context root directory apply to JSP pages.

+//      permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect";

+// };
+//
+// The permissions granted to the context WEB-INF/classes directory
+// grant codeBase "file:${catalina.base}/webapps/examples/WEB-INF/classes/-" {
+// };
+//
+// The permission granted to your JDBC driver
+// grant codeBase "jar:file:${catalina.base}/webapps/examples/WEB-INF/lib/driver.jar!/-" {
+//      permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect";
+// };
+// The permission granted to the scrape taglib
+// grant codeBase "jar:file:${catalina.base}/webapps/examples/WEB-INF/lib/scrape.jar!/-" {
+//      permission java.net.SocketPermission "*.noaa.gov:80", "connect";
+// };
+
+// To grant permissions for web applications using packed WAR files, use the
+// Tomcat specific WAR url scheme.
+//
+// The permissions granted to the entire web application
+// grant codeBase "war:file:${catalina.base}/webapps/examples.war*/-" {
+// };
+//
+// The permissions granted to a specific JAR
+// grant codeBase "war:file:${catalina.base}/webapps/examples.war*/WEB-INF/lib/foo.jar" {
