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

This did not help me!

These are to start inside Eclipse
回答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

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.

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

Using the JVM "agentlib" command-line parameter before "start.jar" did not work for me, but this does:
How to allow Eclipse to remotely debug #Jetty (#JPDA #agentlib:jdwp) on port 8000
You have to create a file, $JETTY_BASE/start.ini (do not change $JETTY_HOME/start.ini) and put the following two lines in it:
- --exec
- -agentlib:jdwp=transport=dt_socket,address=localhost:8000,server=y,suspend=n
