None of the answers here solved my issue (as at February 2020), so I raised an issue at https://issues.apache.org/jira/browse/NETBEANS-3903 and Netbeans fixed the issue!

They're working on a pull request so the fix will be in a future .dmg installer soon, but in the meantime you can copy a file referenced in the bug and replace one in your netbeans modules folder.

Tip - if you right click on Applications > Netbeans and choose Show Package Contents then you can find and replace the file org-netbeans-modules-tomcat5.jar that they refer to in your Netbeans folder, e.g. within /Applications/NetBeans/Apache NetBeans 11.2.app/Contents/Resources/NetBeans/netbeans/enterprise/modules

I had the same problem but none of the answers above worked  The solution for me was to restore the Manager web application that is bundled with Tomcat

For NetBeans to be able to interact with tomcat  it needs the user as setup in netbeans to be properly configured in the tomcat-users xml file  NetBeans can do so automatically   That is  within the tomcat-users xml  which you can find in   CATALINA HOME  conf  or   CATALINA BASE  conf    make sure that the user  as chosen in netbeans  is added the script-manager role   Example  change   lt user password  tomcat  roles  manager admin  username  tomcat   gt    To   lt user password  tomcat  roles  manager-script manager admin  username  tomcat   gt     make sure that the manager-script role is declared   Add   lt role rolename  manager-script   gt    Actually the netbeans online-help incorrectly states      Username - Specifies the user name that the IDE uses to log into the server s manager application  The user must be associated with the manager role  The first time the IDE started the Tomcat Web Server  such as through the Start Stop menu action or by executing a web component from the IDE  the IDE adds an admin user with a randomly-generated password to the tomcat-base-path conf tomcat-users xml file   Right-click the Tomcat Web server instance node in the Services window and select Properties  In the Properties dialog box  the Base Directory property points to the base-dir directory   The admin user entry in the tomcat-users xml file looks similar to the following   lt user username  idea  password  woiehh  roles  manager   gt    The role should be manager-script  and not manager   For a more complete tomcat-users xml file    lt  xml version  1 0  encoding  utf-8   gt   lt tomcat-users gt     lt role rolename  manager-script   gt     lt role rolename  manager-gui   gt     lt user password  tomcat  roles  manager-script  username  tomcat   gt     lt user password  pass  roles  manager-gui  username  me   gt   lt  tomcat-users gt    There is another nice posting on why am I getting the deployment error

This affects    All versions of Tomcat starting from 8 5 3 onwards  All versions of Netbeans up to 8 1  It is fixed in Netbeans 8 2     This is because Netbeans does not  see  that tomcat is started  although it started just fine   I have filed Bug  262749 with NetBeans   Workaround  In the server xml file  in the Connector element for HTTP 1 1  add the following attribute  server  Apache-Coyote 1 1     Example    lt Connector   connectionTimeout  20000    port  8080    protocol  HTTP 1 1    redirectPort  8443    server  Apache-Coyote 1 1    gt    Cause  The reason for that is that prior to 8 5 3  the default was to set the server header as Apache-Coyote 1 1  while since 8 5 3 this default has now been changed to blank  Apparently Netbeans checks on this header   Maybe in the future we can expect a fix in netbeans addressing this issue   I was able to trace it back to a change in documentation   Tomcat 8 5       Overrides the Server header for the http response  If set  the value   for this attribute overrides any Server header set by a web   application  If not set  any value specified by the application is   used  If the application does not specify a value then no Server   header is set     Tomcat 8 0       Overrides the Server header for the http response  If set  the value   for this attribute overrides the Tomcat default and any Server header   set by a web application  If not set  any value specified by the   application is used  If the application does not specify a value then   Apache-Coyote 1 1 is used  Unless you are paranoid  you won t need   this feature     That explains the need for explicitly adding the server attribute since version 8 5 3

It affects at least NetBeans versions 7 4 through 8 0 2  It was first reported from version 8 0 and fixed in NetBeans 8 1  It would have had the problem for any tomcat version  confirmed for versions 7 0 56 through 8 0 28    Specifics are described as Netbeans bug  248182    This problem is also related to postings mentioning the following error output       127 0 0 1   is not recognized as an internal or external command  operable program or batch file    For a tomcat installed from the zip file  I fixed it by changing the catalina bat file in the tomcat bin directory   Find the bellow configuration in your catalina bat file    noJuliConfig set  JAVA OPTS  JAVA OPTS   LOGGING CONFIG     noJuliManager set  JAVA OPTS  JAVA OPTS   LOGGING MANAGER     And change it as in below by removing the double quotes    noJuliConfig set JAVA OPTS  JAVA OPTS   LOGGING CONFIG    noJuliManager set JAVA OPTS  JAVA OPTS   LOGGING MANAGER    Now save your changes  and start your tomcat from within NetBeans
