I installed Netbeans and tryed to access the server\'s manager using: (id/pass)manager/manager, admin/admin, system/password... None of them worked.
If your apache tomcat asking for password,then just follow these steps: go to the home directory of apache then go to webapps folder open the META-INF inside that you will find an xml file named context.xml--open it in edit mode
and REMOVE THE COMMENT FROM the VALVE tag.
After that you dont need any user name and password.
