I have a Windows service (that is, a native .exe) spawning the JVM, loading a bunch of JAR files and invoking their Java code.

How can I remotely debug the Java code running in the service process space?

Note: I tried to use the Java Control Panel to add the usual Runtime Parameters: -Xdebug -Xrunjdwp:server=y,transport=dt_socket,address=4321,suspend=n but apparently these are not read by the spawned JVM, since the aforementioned port is not open on my system.

    Which JDK version are you using? Seems like you are using wrong parameters. Look at this [answer](http://stackoverflow.com/a/22631355/2398521). – Maxim Jan 03 '17 at 22:43
  • Consider setting `suspend=y`. This will cause the JVM to pause until the debugger has connected to your JVM. – StvnBrkdll Jan 03 '17 at 22:50
  • Try `-agentlib:jdwp=transport=dt_socket,address=localhost:4321,server=y,suspend=n`, as indicated by link provided by @MaximDobryakov. And you need to tell the .exe to do that when *it* creates the VM. The Java Control Panel options don't apply there. How to tell the .exe depends on the .exe. – Andreas Jan 03 '17 at 23:20
