How do I set Tomcat Manager Application User Name and Password for NetBeans?

Netbeans Problem: For apache Tomcat server Authentication required dialog box requesting user name and password

This dialog box appear If a user role and his credentials are not set or is incorrect for Tomcat startup via NetBeans IDE,

OR when user/pass set in IDE is not matches with user/pass in "canf/tomcat-user.xml" file

1..Need to check user name and password set in IDE tools-->server

2..Check \CATALINA_BASE\conf\tomcat-users.xml. whether user and his role is defined or not. If not add these lines

<user username="ide" password="EiWnNlBG" roles="manager-script,admin"/>
</tomcat-users>

3.. set the same user/pass in IDE tools->server

restart your server to get effect of changes

I case of tomcat 7 the role has changed from manager to manager-gui so set it as below in the tomcat-user.xml file.

Well if you are using Netbeans in Linux, then you should look for the tomcat-user.xml in

/home/Username/.netbeans/8.0/apache-tomcat-8.0.3.0_base/conf

(its called Catalina Base and is often hidden) instead of the Apache installation directory.

open tomcat-user.xml inside that folder, uncomment the user and roles and add/replace the following line.

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

restart the server . That's all

Follow my steps and be happy:

1.- When you are configuring Netbeans for the first time, they will ask you for a "user" and "pass" for the Catalina-Server.

2.- Type whatever "user" and "pass" . This will modify your "tomcat-users.xml" and will add:

user password="MYPASS" roles="manager-script,admin,tomcat" username="MYUSER"

3.- To use this "user" just restart your TOMCAT WEB SERVER and NETBEANS.

File \conf\tomcat-users.xml, before this line

</tomcat-users>

add these lines

<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>   
<user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

---

Update the 'apache-tomcat-8.5.5\conf\tomcat-users.xml file. uncomment the roles and add/replace the following line.and restart server

tomcat-users.xml file

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

---

You will find the tomcat-users.xml in \Users\<Name>\AppData\Roaming\Netbeans\. It exists at least twice on your machine, depending on the number of Tomcat installations you have.

---

Use something like this to update your tomcat users.

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

Tomcat users file is located inside conf folder of tomcat installation. To find the path of catalina_base you can use the command: ps aux | grep catalina You can find one of the values -Dcatalina.base=/usr/local/Cellar/tomcat/9.0.37/libexec

Most Important:

Don't forget to remove the comment lines from the tomcat-users.xml just before the start of the roles. <!-- -->

One simple way to check your changes to that file in Tomcat 8 + is to open a browser to: http://localhost:8080/manager/text/list

---

Go to apache-tomcat\conf folder add these lines in

tomcat-users.xml file

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

and restart server
