Tapestry5 application not running on WTP Tomcat server

My Tapestry 5 application is running fine with a maven "tomcat:run" build, but not when I use a Tomcat WTP开发者_C百科 server.

I.E: I created a tapestry 5 project based on the tapestry 5 quickstart maven archetype. At the beginning, it works fine with both servers.

After playing a little bit with the dependencies (i.e. adding and then removing the exact same libraries), I get a 404 error on each of my pages when I start the WTP server, while the project is correctly running with a maven "tomcat:run".

I tried to clean up everything, rebuild from scratch... but so far nothing.

What could explain such a behaviour? Where should I look for fixing this?

Thanks

You can turn-on all logs in the tomcat: conf/logging.properties, add line org.apache.catalina.level=FINEST
