Unable to open debugger port in IntelliJ

Question

Unable to open debugger port in intellij. The port number 9009 matches the one which has been set in the configuration file for the application.

Answer 1

This one worked for me-- If the issue still persists (in case you are not using a glassFish server), then close your JIdea and stop the server. This will disable the ports connectivity. Then start your server and JIdea, this will start fresh connectivity with the ports, resolving the issue.

Answer 2

1. In glassfish\domains\domain1\config\domain.xml set before start server:

      <java-config classpath-suffix="" debug-options="-agentlib:jdwp=transport=dt_socket,address=9009,server=y,suspend=n" java-home="C:\Program Files\Java\jdk1.8.0_162" debug-enabled="true" system-classpath="">

or set debug-enabled="true" server=y,suspend=n in http://localhost:4848/common/index.jsf

2. In current Idea 2018 - Server Run Configuration - Debug - Port - address

Answer 3

Merely hitting the debug icon again fixed my problem in a few seconds.

Answer 4

I had the same issue, I just have to remove the HTTP protocol from the URL. That's it.

I hope it works for you.
