can not access to tomcat7 manager application

Question

I've installed TOMCAT7 via synaptic but can not access manager application. What am I doing wrong or what is missing, I can not figure out.

My complete settings and o/p are listed below:

When I do http://127.0.0.1:8080/manager/html, it shows 403 Access Denied.You are not authorized to view this page...

My OS is Ubuntu 14.04

**java -version**
java version "1.7.0_55"
OpenJDK Runtime Environment (IcedTea 2.4.7) (7u55-2.4.7-1ubuntu1)
OpenJDK 64-Bit Server VM (build 24.51-b03, mixed mode)

the o/p of the command:

/var/lib/tomcat7/webapps$ ls
manager  ROOT

The o/p of the command shows:

ls -l /var/lib/tomcat7/webapps/
total 4
lrwxrwxrwx 1 root root   32 Aug  3 18:31 manager -> /usr/share/tomcat7-admin/manager
drwxr-xr-x 3 root root 4096 Aug  3 10:42 ROOT

and I've set /etc/environment as:

PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

CATALINA_HOME="/var/lib/tomcat7"
CATALINE_BASE="/var/lib/tomcat7" 
JAVA_HOME="/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java"

tomcat-users.xml file

<tomcat-users>
 <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>  
</tomcat-users>

Please can anyone explain what is missing or what is going wrong with this?

Thanks!!!

Answer 1

I've changed the tomcat-users.xml file inside the

/etc/tomcat7/tomcat-users.xml

my previous settings:

<tomcat-users>
 <role rolename="tomcat"/>
  <role rolename="role1"/>
  <user username="tomcat" password="tomcat" roles="tomcat"/>  
</tomcat-users>

changed to:

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

Now I can access the link
