Hi shams.hq,
I don't understand how you bother to copy an application in your server directories. It's really piece of cake to deploy with Tomcat.
All you have to do :
- with Netbeans, you build the project : a WAR file will be created in the dist directory of your project;
- launch the server, if it's not running;
- with your web browser, connect to the Tomcat Manager;
- from there, you may upload and deploy the WAR file of your project.
Et voilà ! Tomcat will unzip the WAR and install your classes and libraries at the right place.
