Debugging web application on Tomcat
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.

when i do a Deploy? It makes my jar. I have to Launch manually on the
server (in theory), and then headless, or run in gui.
Its a WIP.

I do Spring and starter=web, on my classpath; -- you'd have to review
the tec.xml, but thats not public yet.

How have you installed Tomcat 9 on your System?

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: ""
NOTE: Picked up JDK_JAVA_OPTIONS: --add-opens=java.base/java.lang=ALL-UNNAMED --add-opens=java.base/java.io=ALL-UNNAMED --add-opens=java.base/java.util=ALL-UNNAMED --add-opens=java.base/java.util.concurrent=ALL-UNNAMED --add-opens=java.rmi/sun.rmi.transport=ALL-UNNAMED
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.

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.
