Attaching a debugger to a Windows service running an install4j application is very simple once you understand that VM parameters to an install4j executable need to be prefixed with -J
Take the debug command line options, typically somehting like:
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005
prefix the -J and insert into the windows service "Start parameters" field:
start the service and connect your debugger!
