Remote debug Jetty (no mvn, no plugins)

Question

Past scenario
- Work with Tomcat and start in debug mode and Remote Debug with Eclipse.
- Define a port and connect with eclipse in this debug/remote port.
- Use to debug servers in other hosts/servers

Today scenario
Now, I'm using Jetty and I've try to do the same, but with no success, could anyone help-me with that?
I did not use Maven, and did not want to start Jetty inside from my Eclipse.

Environment:
Windows XP
Java V. 5
Jetty V. 6.1.15

These are to start inside Eclipse

Answer 1

This is what we are adding to our JBoss command line while development:

-Xdebug -Xrunjdwp:transport=dt_socket,address=8787,server=y,suspend=n

Then we launch the eclipse remote debugging and connection to this port.

Update:

To run from jar (standalone) do the following

java -Xdebug -Xrunjdwp:transport=dt_socket,address=8585,server=y,suspend=n -jar start.jar 

Answer 2

For remote debugging you should use JPDA. There's a sort of tutorialish article about it available here.

In short, start your JVM with the argument:

-agentlib:jdwp=transport=dt_socket,server=y,address=8000,suspend=n

and you are able to connect to the underlying JVM listening on port 8000 via the standard Eclipse debugger.

Answer 3

If you will use mvn jetty:run one day, you have to

export MAVEN_OPTS="-Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n"

appending -Xdebug ... doesn't works
