<?xml version='1.0' encoding='utf-8'?>
<tomcat-users xmlns=""
              xsi:schemaLocation=" tomcat-users.xsd"
  <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"/>
<user username="tomcat" password="tomcat" roles="manager-gui"/>

Restart the tomcat to  have access to the web manager.
