无法通过Eclipse进行Tomcat调试

Question

I've made a script called debug.sh and placed it under the bin directory (start it with ./debug.sh ) to start Tomcat 8 in debugging mode:

set JPDA_ADDRESS=8000
set JPDA_TRANSPORT=dt_socket
set JAVA_OPTS=-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n
bash catalina.sh jpda start

But if it started, there is now message which says, that Tomcat is listening on port 8000. Also if I type

netstat -nat

there is no application listening on port 8000.

What exact configuration do I have to set, to remote debug my Tomcat 8 server which is running on a specific IP or do I have just a little problem in my script?

This answer has been updated following the comments, I did not understand the problem in the first place.

I guess you have followed that doc : this is about developing Tomcat itself.

I am not sure you are using the proper way to configure the port (I don't know your specific configuration details). In a standard environment, the ports are configured in the server.xml (note that several different ports are used by Tomcat for the different services).

To remotely monitor your server, you should use a JMX client. As far as I know, Eclipse doesn't include one (or at least not one documented) - you could code one as this is a Java specification (JSR262) . You have one in a standard Java environement ( JConsole ). By default, JMX is not enabled on Tomcat. If you need to enable it, the fine way is to follow the doc .

Tomcat JMX monitoring and JConsole are both available in most versions of Tomcat and the Java runtime.

The following exchange seems to be about your problem.
