Debugging maven-jetty web application in NetBeans

by Vijay Kiran

Setup Jetty to run with Debugging enabled on port 8000

export MAVEN_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000"

Run Jetty using Maven Plugin

mvn jetty:run

In NetBeans, Goto Debug→ Attach Debugger menu. Select Java Debugger(JPDA) and specify the port as 8000. Now you can debug the webapplication using NetBeans.

    I have always disabled the Attach Debugger menu option in maven projects (NB 6.7.1) :-(

    Thanks a lot! Worked for me!

    Great tip! I would add export MAVEN_OPTS=”$MAVEN_OPTS -Xdebug -Xrunjdwp:transport=dt_socket,server=y,address=8000″ as to not loose any previous options (for instance memory related).
