I'm using NetBeans 11.1, but it should be the same for 11.2. Don't use the distribution's Tomcat. Instead, do the following: 1. Download the latest versions (I use 9, 8.5, and 7) from tomcat.apache.org. 2. Create a top level directory for convenience in your home directory. I use ~/Apache 3. Copy the .tar.gz files for the various Tomcats into that directory 4. Unpack the .tar.gz files You should now have directories apache-tomcat-7.0.x, apache-tomcat-8.5.x, and apache-tomcat-9.0.x. 5. In each apache-tomcat-x.y.z directory, you should find a conf folder 6. In the conf folder, you will find tomcat-users.xml 7. Edit tomcat-users.xml per instructions found in the comments of that file. You will want a manager-script role / user so that NetBeans can control the server. 8. When you add the server to NetBeans, use the same user name and password created in step 7. The reason for doing all of this is quite simply, permissions. NetBeans deploys WAR files to Tomcat by copying a context.xml file to $CATALINA_BASE/conf/Catalina/localhost/app.xml. The contents of that app.xml file contain the actual location of the web application (it's not copied over to the Tomcat distribution), as well as the context path served by Tomcat. If you don't have write permissions to $CATALINA_BASE/conf/Catalina/localhost, then the deploy / undeploy will not work. I normally only run one Tomcat instance at a time on my development systems. However, if you want to run more than one Tomcat instance, you'll have to edit $CATALINA_BASE/conf/server.xml and change at least the shutdown port and HTTP/1.1 ports to be unique across all Tomcat instances. This setup is quite nice, in that I have full access to the Tomcat installation with my user account. I can add jars to $CATALINA_BASE/lib (for example, JDBC jars), and add environment settings to $CATALINA_BASE/bin/setenv.sh. Finally, if you get stuck on a Tomcat-related issue, you're more likely to get help on the Tomcat mailing list if you've installed the latest version of Tomcat from tomcat.apache.org rather than use a distribution version. It's not that distribution versions are necessarily bad, it's just that each distribution does things differently. Apache Tomcat from tomcat.apache.org is set up the same way regardless of OS (OK - .sh versus .bat files not withstanding). . . . just my two cents /mde/
