Tomcat and servlet the nightmare

Hello,
it's a nightmare to use Tomacat for servlet. Now
I've this file

web.xml

// You can assign additional permissions to particular web applications by
// adding additional "grant" entries here, based on the code base for that
// application, /WEB-INF/classes/, or /WEB-INF/lib/ jar files.
//
// Different permissions can be granted to JSP pages, classes loaded from
// the /WEB-INF/classes/ directory, all jar files in the /WEB-INF/lib/
// directory, or even to individual jar files in the /WEB-INF/lib/ directory. 
//
// For instance, assume that the standard "examples" application
// included a JDBC driver that needed to establish a network connection to the // corresponding database and used the scrape taglib to get the weather from 
// the NOAA web server.  You might create a "grant" entries like this:
//
// The permissions granted to the context root directory apply to JSP pages. 
// grant codeBase "file:${catalina.home}/webapps/examples/-" {
// permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect"; 
//      permission java.net.SocketPermission "*.noaa.gov:80", "connect";
// };
//
// The permissions granted to the context WEB-INF/classes directory
grant codeBase "file:${catalina.home}/webapps/examples/WEB-INF/classes/-" {
};
//
// The permission granted to your JDBC driver
// grant codeBase "jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/driver.jar!/-" { // permission java.net.SocketPermission "dbhost.mycompany.com:5432", "connect"; 
// };
// The permission granted to the scrape taglib
// grant codeBase "jar:file:${catalina.home}/webapps/examples/WEB-INF/lib/scrape.jar!/-" { 
//      permission java.net.SocketPermission "*.noaa.gov:80", "connect";
// };
With this I can enter in web-inf and servlet of my webapp, but this is the nighmare. I try to enter in the example page and the servlet is displayed white pages, and the servlet in my webapps displayed white page. Why? The servelet to try my webapps is the servlet for the example HelloWorldExample that before the modification of web-user and grant displayed correct content. 
What do I miss?
Sincerally yours,
Fabbris Pierluigi
