Our application is running on Tomcat, and sometimes the backend code has some problem, so we need to remote debug the problem.
This is frequently used during our development.
So I record the code here for later use.
-Xdebug
-Xrunjdwp:transport=dt_socket,address=9999,server=y,suspend=n
The default address is 8000, and I change it to 9999, because it might has security issue, and this should not always open, just add this for remote debug.
