My problem solution is very embarrassing but who knows    perhaps it happened to someone else   My solution  Turn off proxy  For the past two hours I ve been wondering why my manager would not load   the root was cached so it loaded   I had set the browser s proxy to proxy traffic to my house

I couldn t log in to the manager app  even though my tomcat-users xml file was set up correctly  The problem was that tomcat was configured to get users from a database  An employee who knew how this all worked left the company so I had to track this all down   If you have a web application with something like this in the projects web xml    lt security-role gt       lt role-name gt manager lt  role-name gt   lt  security-role gt    You should be aware that this is using the same system for log ins as tomcat  So where ever your manager role user s  are defined  that is where you should define your manager-gui role and user  In server xml I found this     lt Realm className  org apache catalina realm JDBCRealm      driverName  org gjt mm mysql Driver      connectionURL  jdbc mysql   localhost  lt DBName gt  user  lt DBUser gt  amp amp password  lt DBPassword gt       userTable  users  userNameCol  user name  userCredCol  user pass      userRoleTable  user roles  roleNameCol  role name    gt    That tells me there is a database storing all the users and roles  This overrides the tomcat-users xml file  Nothing in that file works unless this Realm is commented out  The solution is to add your tomcat user to the users table and your manager-gui role to the user roles table   insert into users  user name  user pass  values   tomcat     lt changeMe gt     insert into user roles  user name  role name  values   tomcat    manager-gui      You should also have a  manager-gui  rolename in the roles table  Add that if it doesn t exist  Hope this helps someone

You have to check if you have the folder with name manager inside the folder webapps in your tomcat   Rubens-MacBook-Pro tomcat rfanjul  ls -la webapps  total 16 drwxr-xr-x   8 rfanjul  staff   272 21 May 12 20   drwxr-xr-x  14 rfanjul  staff   476 21 May 12 22    -rw-r--r--   1 rfanjul  staff  6148 21 May 12 20  DS Store drwxr-xr-x  19 rfanjul  staff   646 17 Feb 15 13 ROOT drwxr-xr-x  51 rfanjul  staff  1734 17 Feb 15 13 docs drwxr-xr-x   6 rfanjul  staff   204 17 Feb 15 13 examples drwxr-xr-x   7 rfanjul  staff   238 17 Feb 15 13 host-manager drwxr-xr-x   8 rfanjul  staff   272 17 Feb 15 13 manager   After that you will be sure that you have this permmint for you user in the file conf tomcat-users xml       lt role rolename  admin-gui   gt   lt role rolename  manager-gui   gt   lt user username  test  password  test  roles  admin-gui manager-gui   gt    restart tomcat and stat tomcat again   sh bin shutdown sh  sh bin startup sh   I hope that will works fine for you
