Tomcat – I can’t access Tomcat 7 manager when Tomcat is running through IntelliJ Idea Ultimate 12

intellij-ideatomcattomcat7

I am trying to access tomcat manager by using 

http://localhost:8080/manager

but I am always denied the entrance after I enter the password.
I get the following message :

403 Access Denied

You are not authorized to view this page.

If you have already configured the Manager application to allow access
and you have used your browsers back button, used a saved book-mark or
similar then you may have triggered the cross-site request forgery
(CSRF) protection that has been enabled for the HTML interface of the
Manager application. You will need to reset this protection by
returning to the main Manager page. Once you return to this page, you
will be able to continue using the Manager appliction's HTML interface
normally. If you continue to see this access denied message, check
that you have the necessary permissions to access this application.

If you have not changed any configuration files, please examine the
file conf/tomcat-users.xml in your installation. That file must
contain the credentials to let you use this webapp.

For example, to add the manager-gui role to a user named tomcat with a
password of s3cret, add the following to the config file listed above.

Note that for Tomcat 7
onwards, the roles required to use the manager application were
changed from the single manager role to the following four roles. You
will need to assign the role(s) required for the functionality you
wish to access.

manager-gui – allows access to the HTML GUI and the status pages
manager-script – allows access to the text interface and the status
pages manager-jmx – allows access to the JMX proxy and the status
pages manager-status – allows access to the status pages only The HTML
interface is protected against CSRF but the text and JMX interfaces
are not. To maintain the CSRF protection:

Users with the manager-gui role should not be granted either the
manager-script or manager-jmx roles. If the text or jmx interfaces are
accessed through a browser (e.g. for testing since these interfaces
are intended for tools not humans) then the browser must be closed
afterwards to terminate the session. For more information – please see
the Manager App HOW-TO.

Here is my tomcat-users.xml :

<tomcat-users> 
<role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager-gui"/>
  <user username="tomcat" password="s3cret" roles="admin-gui,standard,manager-gui"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
</tomcat-users>

I am running tomcat 7 through intellij idea 12 ultimate.
I am using Mountain Lion operating system.
Thank you.

I edited two files : server.xml & tomcat-users.xml

STEP 1 : I added this line to the server.xml, this line must be added under Engine context same as the picture:

<Realm className="org.apache.catalina.realm.MemoryRealm" />

here you can see the picture :

enter image description here

STEP 2 : then I edited tomcat-users.xml and added the lines below : 

<!--
  NOTE:  The sample user and role entries below are wrapped in a 
  comment and thus are ignored when reading this file. Do not forget
  to remove <!.. ..> that surrounds them.
-->

  <role rolename="tomcat"/>
  <role rolename="role1"/>
  <role rolename="manager"/>
  <role rolename="manager-script"/>
  <role rolename="manager-gui"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>
  <user username="both" password="tomcat" roles="tomcat,role1"/>
  <user username="role1" password="tomcat" roles="role1"/>
  <user username="admin" password="tomcat" roles="manager-gui,manager-script "/> 

</tomcat-users>

NOTE : I recommend you to copy and paste my text and replace it by yours

Restart tomcat and you're ready to go !
