I'm trying to follow a tutorial to make an extremely basic Java web application in NetBeans.
When I try to run it, a dialogue box appears title "Authentication Required". Inside the dialogue box there the heading "Tomcat Manager Application" and fields for "User Name" and "Password."
Investigating this, I've come to understand that I should edit the file
\TOMCAT_HOME\conf\tomcat-users.xml
to include something like:
<user username="user" password="password" roles="standard,manager"/>
so I've done that, but it hasn't helped yet.
Can anyone provide some insight? I'm using Tomcat 6.0.20, NetBeans 6.7.1, and Windows Vista. I'm using jdk1.7.0, but Java hasn't really entered into this project yet.
The answer is
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.
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.
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
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.
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
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"/>
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. <!-- -->
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

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"/>
