This project makes possible to debug java web applications via http protocol. Spring-boot devtools has the same functionality, but sometimes it's not an option to make legacy app spring-boot based.
Concepts of remote debugging by http protocol is the same as defined in spring-boot manual:
- you start a debugee application with additional command line args like
-Xdebug -Xrunjdwp:server=y,transport=dt_socket,suspend=n - you start a debugee client side application
- you start a debuger from IDE you like, using jdwp port 8000 and host localhost
- debugee client reads traffic from port 8000 and passes it to a remote debugee
