Hi Guys, thank you for both answers, which were useful.
In case anyone else runs into similar issue and finds this thread in the archives, I'll note that I ended up needing to replace the maven-jetty-plugin in the pom.xml with the jetty-maven-plugin (much newer version), configured as shown by Svein, but I also added: <systemProperties> <systemProperty> <name>tapestry.execution-mode</name> <value>development</value> </systemProperty> </systemProperties> to match the old plugin configuration. Finally, I needed to run "mvn jetty:run" with sudo on my mac, otherwise it failed to bind to port 80, although I'm exploring another way to do it with https://github.com/Castaglia/MacOSX-authbind.
