@JunQianZ Port 9090 is the application port (for http), not the debug port. One of our team members published a dedicated tomcat extension https://marketplace.visualstudio.com/items?itemName=adashen.vscode-tomcat, i would suggest you to use it for tomcat debugging.

@testforstephen so what should be the debug port? and I did use the tomcat debugging. the tomcat is configured launched successfully from my visual studio code.

Please refer to this doc for enabling remote debugging on tomcat. https://stackoverflow.com/questions/3835612/remote-debugging-tomcat-with-eclipse
