is that the IDE doesn't support it yet.
NetBeans most certainly supports debugging a running Tomcat started with the "jpda" option
through the "Debug -> Attach" menu
I am doing this on a regular basis with applications that can't be deployed
through NetBeans (e.g. Liferay portlets).
If you can't start Tomcat from within NetBeans, then start it on the command
line (after deploying your WAR file manually)
In my experience you need to use the "catalina" script, because "startup"
script does not seem to pass the parameters correctly.
When using
catalina.bat jpdba run
You will see something like this:
Using CATALINA_BASE: "d:\etc\apache-tomcat-9.0.73"
Using CATALINA_HOME: "d:\etc\apache-tomcat-9.0.73"
Using CATALINA_TMPDIR: "d:\etc\apache-tomcat-9.0.73\temp"
Using JRE_HOME: "c:\etc\Java11"
Using CLASSPATH:
"d:\etc\apache-tomcat-9.0.73\bin\bootstrap.jar;d:\etc\apache-tomcat-9.0.73\bin\tomcat-juli.jar"
Using CATALINA_OPTS: ""

Listening for transport dt_socket at address: 8000
25-Mar-2023 08:55:20.303 INFORMATION [main]
org.apache.catalina.startup.VersionLoggerListener.log Server Version:
Apache Tomcat/9.0.73
The important bit is: the "Listening for transport dt_socket at address: 8000"
If that shows up, you can use "Debug -> Attach" from within NetBeans to debug
your application inside Tomcat.

Probably, the problem with this...., and maybe lombok, is that the IDE doesn't
support it yet.
It depends on who's doing what and how.
Everything I make, works, mostly, ... , I continually make changes and test.

Last year I have developed a Spring-Boot web application.
It was originally developed as a JAR but later converted to a WAR and deployed
to the Tomcat 9 on a production server.
Last week, a bug was found and I need to fix it.
Not to change the configuration, I have installed Tomcat 9 on my Windows laptop
and was trying to debug the application on it.
When I click on “Debug” in my Netbeans 16, it builds the war but than trying to
stop Tomcat for a while and then fails to do it.
I did stop Tomcat manually and tried to do it again, but than Netbeans failed
to start Tomcat.
Looks like there are some permission issues. Can someone tells me how to fix it.
I remember, long ago, with Netbeans 8.2 and Tomcat6 I haven’t had a problems
deploying apps without start/stop.
A workaround might be to start Tomcat manually in debug mode (using "catalina jpda
run")
Then use "Debug -> Attach" to attach to the running Tomcat instance.
