Tomcat manager ERR_CONNECTION_REFUSED

Question

I use Eclipse IDE and I've JBOSS and Tomcat installed: everything seems to works, but... When I try to connect to http://localhost:8080/manager/html to use the administration panel, I get this error:

ERR_CONNECTION_REFUSED

this is my tomcat-users file:

<?xml version='1.0' encoding='utf-8'?>
<tomcat-users>

<role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>


  <role rolename="manager-gui"/>
  <role rolename="manager-script"/>
  <user username="mauro" password="mauro"
roles="manager-gui,manager-script "/>
</tomcat-users>

Windows firewall is disabled, and until now I've never had problems to see all my JPS

Answer 1

Give role manager-gui to some user

<user username="manager" password="tomcat" roles="manager-gui"/>

NOTE: By default, no user is included in the "manager-gui" role required to operate the "/manager/html" web application. If you wish to use this app, you must define such a user - the username and password are arbitrary.
