An example of Java Remote debug
1. start Jetty server under debug mode via mvn jetty:run
2. In Eclipse, create a new Debug configuration->Remote Java Application
Specify Host as localhost and port 8000:
Click debug button:
You should observe that the Jetty server listening to port 8000 has accepted this debug request and start application via localhost:8080 now:
3. go to localhost:8080, perform action to trigger the breakpoint:
And now in Eclipse, breakpoint is triggered!
Note: if you meet with error message “bind error, address already in use”, please first use “netstat -lp” to find the process id which occupies the address and kill that process by kill -9 <pid>.
If still does not work, restart the virtual machine instance.
