I ran a Web application project. I kept getting a message saying:

Access to Tomcat server has not been authorized. Set the correct username and password

with the “manager-script” role in the Tomcat customizer in the Server Manager.

I checked the tomcat-users.xml in the “conf” folder of Tomcat, and added the 2 lines as below:

  <role rolename=”manager-script”/>
  <user username=”user” password=”user” roles=”manager-script”/>

It still didn’t work.

Late on, I found I made two mistakes:

1) I changed the wrong tomcat-users.xml. I had two Tomcat in my computer.
2) I didn’t remove this: <!–  –>. Within this, everything is ignored.

Now, it works :)))))))))))
