To make the JBoss JVM listen for debugger, you set some params in the
run.bat script (or run.sh/run.conf on *nix). There should be a section
already in the run script to turn debugging on -- look for "JPDA
options". You just uncomment the lines to enable remote debugging.
Note that by default it sets "suspend=y", which will cause the JVM to
wait until you connect the debugger before it does anything (like start
the server). This is useful if you need to debug things at startup, but
I normally set "suspend=n", so the server will start normally, and I can
just connect and disconnect the debugger whenever I want. You probably
want to change this to "suspend=n".
Note what the port number is (default is 8787) -- you will need to tell
Eclipse the port number when you setup the debug session.
No other files are affected.
Debugging (JPDA) is a standard feature of Java, and has nothing to do
with Maven.
In Eclipse, you setup a debug session, and tell eclipse which server and
port number the JBoss JVM is listening to (e.g. localhost:8787).
I suspect that this is what was really happening in your previous setup
anyway, and that the Eclipse WTP plugin just took care of the details
for you.

Hi Max,
I think remote debug local server(I'm using JBoss) would be OK.
But it there alternative approach for local debugging?
If use remote debugging, shall I re-config some parameters in web.xml or
other conf files?
Thanks!
a cup of Java, cheers!

It sounds like your primary requirement is "how can I debug my webapp".
My project uses Maven to build and deploy a webapp to a server running
on the local machine, and then we connect the Eclipse debugger to the
local server via the standard Java "remote" debugging interface.

Hello,
Currently, I use an Eclipse plugin(WTP) to create a Web application.
And I use the plugin to export(deploy) the Web application to an
Web/Application Server(JBoss)'s deploy directory.
Then I can debug the application when the server is running.
The function is provided by the plugin.
If the project isn't created by the plugin, the plugin cannot deploy the
app(may since directory layout).
And I cannot debug the app with server(it's a serious problem).
Now I want to use Maven and it's standard directory structure.
But how Maven to fulfil the requirement?
